The programmable logic controller is the
workhorse of industrial control systems.
It uses digital and analog I/O modules to
interface to sensors, actuators and other
equipment. These I/O modules must
meet stringent electrical specifications
and designers face challenges in condi­
tioning and converting these signals. In
addition, increasing levels of embedded
processing and connectivity can be seen
on these modules.

I/O modules can be classified as analog
input (AI), analog output (AO), digital
input (DI) and digital output (DO). They
are usually cate­go­rized into 2-, 4-, 8- and
16-channel modules. I/O modules need
to meet stringent electrical specifications
such as the IEC 61000-4 family of electro
magnetic compatibility (EMC) tests for
surge, ESD (electro­static discharge) and
EFT (electrically fast transients). They
also need short-circuit and over­load
protection. All these modules include
isolation between the control side and
the field side via DC-DC converters and
isolation on the digital commu­nication
side between the field devices and the
digital backplane. Communication over
the digital backplane is done by a variety
of interfaces (RS-485, CAN, Ethernet,
LVDS, etc.) In distributed control systems
or between equipment, industrial field­
buses (PROFIBUS®, DeviceNet™,
CANopen®, Modbus®, EtherCAT®,
EtherNet I/P™, PROFINET®, SERCOS®,
POWERLINK, etc.) are used for commu­
nication. On the following pages we
discuss solutions from TI for these
various I/O types.
PLCs can be segmented by I/O count
and scan rates. They can also be classi­
fied as brick type versus modular PLCs.
A small or brick PLC has a fixed number
of connections for inputs and outputs.
Modular PLCs have a chassis (also called
a rack) into which are placed modules
with different functions. The processor
and selection of I/O modules is custom­
ized to fit the application. A modular PLC
consists of the central processing unit
(CPU), a power supply and various I/O
modules. The CPU performs the main
controller functions like scanning data
and running control sequences. The
power supply unit converts line power
to 24 volts. The I/O modules are used
to measure data from sensors and to
control various actuators. Together, the

TI Designs
Texas Instruments analog input solutions address a wide range
of analog input modules in the factory and process automation
industry, including temperature (thermocouple and RTD), 4-20
mA and single ended or differential 0-5 V, 0-10 V, ±5 V and ±10 V.
The TI Designs provide insights in how to handle multiple
channels per module, Delta-Sigma and SAR ADC based
signal acquisition and universal input stages. Industry 4.0
(Industrie 4.0) requirements for diagnostics and HART are also
showcased. Small footprint and high efficiency isolated power
supplies for generating positive and negative voltages help
meet the demands for more channels per module and smaller
form factors.

The TIDA-00018 reference design enables faster development of high precision
temperature measurement solutions using 24-bit delta-sigma ADC and most widely
used temperature sensors like thermocouple and RTD. The design guide will address
the sensor signal conditioning, thermocouple cold junction compensation, ratiometric
measurement technique for RTD, recommended software flow, sensor linearization,
sensor diagnostics, transient protection, PCB layout and other practical design
considerations for achieving high precision robust design for temperature measurement
in industrial applications. The temperature sensor interface module is a fully isolated
design, which is essential for small sensor signal measurement. The heart of this
reference design is a 24-bit delta-sigma ADC that provides a high resolution, high–
integration, low-noise, and low-cost complete sensor analog front-end (AFE) for DC
sensing applications. This ADC also makes it suitable to interface with different types
of sensors, thus saving board space, reducing design efforts, decreasing the time to
market, and lowering BOM cost. Furthermore, external protection circuitry has been
successfully tested for compliance with regulatory IEC61000-4 EFT, ESD, and surge
standards. Compliance to IEC61000-4 is necessary to ensure that the design not only
survives but also perform as intended in the harsh/noisy industrial environment.

Connectivity & interface for I/O module
Overview / microcontrollers
Connectivity options ranging from Ethernet ports to UARTs to
simple SPI ports are required. Ethernet enables integration of
field devices to the corporate enterprise network. There are a
number of fieldbus options – both serial (RS-485, DeviceNet™,
PROFIBUS®, CAN, etc.) and Ethernet based. Extended cable
reach and diagnostics to debug wire breaks provides system
designers significant value. Integrated digital isolation on the
interface transceivers is highly desirable to reduce board space.

Power for I/O module
Overview / TI Designs
To protect against transients and ground
loops, the module is electrically isolated
from the control side. The design can be
customized for perfor­mance and cost
by using a DC-DC converter. Finally,
using LDOs with good PSRR (power
supply rejection ratio) to supply the
precision analog circuitry will reduce the
power supply ripple and preserve system
accuracy and resolution.

Description
Key Features
The TIDA-00129 reference design is a 1 W power supply with dual isolated outputs for
1 W small form factor power supply space constrained applications. With 24 V and 3.3 V isolated outputs, this design was
with isolated dual output for PLC
created specifically to power programmable logic controller (PLC) I/O modules in a
I/O modules
factory automation setting. This design was created to comply with IEC 61010-1, which
in turn will provide a designer faster time to market with their own design.
• Designed to comply with IEC61010-1
• Small form factor for space constrained I/O cards: 51 x 40 x 5.97 mm
(L x W x H)
• Up to 87% efficiency for low heat dissipation in small plastic housings
• A complete and cost effective design for I/O cards
• ±10% output voltage accuracy
• Wide input voltage range: 1 7V to 36 V (24 VNOM)
The TIDA-00400 isolated power supply reference design provides multiple isolated
Isolated power supply for
outputs to supply the bias voltage needed in a programmable logic controller (PLC) IO
programmable logic controller
module. It generates 3 isolated outputs: ±15 V@30 mA and +5 V@4 0mA. These voltage
(PLC) I/O modules reference design rails can satisfy most of the required voltage rails in the I/O modules, such as the opamp, DAC bias, RS-485 transmitter and digital isolator power supplies.
• Wide input voltage range: 18 to 30 V (24 VNOM)
• Non-Isolated output: 3.3 V with 50 mA
• Three isolated outputs:
+15 V with 30 mA
-15 V with 30 mA
+5 V with 4 0mA
• Small form factor for space constrained I/O cards 51 x 51 x 8 mm (L x W x H)
• Primary-side regulation (no need for optocoupler) increases lifetime reliability
Adaptive power supply for PLC
analog output module with output
channel protection
The TIDA-00231 is a reference design for an industrial programmable logic controller
(PLC) analog output module. The design provides a unique power saving solution for a
digital-to-analog converter (DAC)-based analog current output module with an adaptive
power supply. This adaptive power supply dynamically regulates the AVDD supply of
the DAC and limits power losses to < 50 mW for typical load resistance of > 300 Ω.
The analog output can source current up to 24 mA. This reference design includes the
necessary on-board protection circuit and has been tested to IEC61000-4 standard EFT,
ESD, and surge requirements with I/O Controller platforms. The protection circuitry does
not negatively affect the design and test results showed typical unadjusted errors were
less than 0.2% FSR and calibrated accuracy is 0.05%.
• 16-bit user configurable analog current output
• Accuracy
• Un-calibrated better than ±0.2% FSR at 25°C
• Calibrated better than ±0.05% FSR at 25°C
• Adaptive power supply reduces system power dissipation- power losses across
FET are limited to < 50 mW for typical load resistance > 300 Ω
• Reverse voltage protection for analog output
• On-board isolated Flybuck™ power supply with inrush current protection
• Designed to comply with IEC61000-4 standards for ESD, EFT, and surge
Isolated DC/DC power supply
for PLC analog input and output
modules
The TIDA-00401 reference design is an isolated DC/DC turn-key solution. For a 10 W
isolated power supply with wide input voltage range, no opto-coupler feedback and low
number of external components the Flybuck™ topology is superior to a flyback design.
The single side populated PCB board provides a convenient tool for evaluation and
on-the-fly optimization of the design, with adequate headers, jumpers and test points for
applications like PLC analog Input/Output modules.
• Isolated DC/DC power supply for 15 V to 36 V Input, up to 10 W of output power
• Low quiescent current up to 20 mA
• Open-loop, optocoupler-less design
• Synchronization output and fixed switching frequency enable use in noise
sensitive applications
• Flexible configurable board enables easy evaluation and modification
• Design guide provides detailed description and performance test data
16-Channel status LED driver for
PLC modules reference design
The objective of the TIDA-00560 reference design is to demonstrate a multi-channel
LED driver as required in PLC I/O modules to indicate the status of several analog,
digital input, and output channels. Important requirements for such a design like low
static current, low component count, minimal PCB requirements, and an integrated LED
diagnostic features are addressed with this design. The two-layer single-side component
mounted board is compatible with the BeagleBone cape specification for rapid evaluation
with the BeagleBone platform.
• 16-channel shift register with wide range constant current sinks (2-35 mA)
• Two-level selectable LED brightness to compensate for ambient light
• Diagnostic features: LED open and LED shorted to ground
• Standardized SPI connects seamlessly to standard processors
• Number of channels can be increased by daisy-chaining multiple LED driver
devices
• BeagleBone cape support for easy evaluation
Analog input and output modules are a standard component in programmable logic
controllera (PLC) or distributed control systems (DCS). More channels per module
and slimmer modules bring design challenges to the isolated power supply in those
Ultra-small 1 W, 12 V-36 V iso
modules. Anyone facing those challenges will benefit from TIDA-00237, as the total
power supply for analog prog logic
design footprint is less than 2.54x2.54 mm and less than 5 mm height. It uses a Flybuck
controller modules
approach which means no optocoupler feedback with wide input voltage range of 12V36 V. The design provides ±15 V and 5 V isolated, low noise outputs optimal for driving a
data converter or analog front end.
Texas Instruments
• Wide input voltage range: 12 V to 36 V (24 VNOM)
• 3 isolated outputs: 15 VISO at 3 0mA ultra low noise, -15 VISO at 30 mA ultra
low noise, 5 VISO at 40 mA
• ±2.5% output voltage accuracy
• Ultra low profile < 5 mm
• IEC 61131-2 compliant

Industrial Ethernet for industrial automation exist in more than 30 industrial
standards. Some of the well-established real-time Ethernet protocols, like EtherCAT,
EtherNet/IP, PROFINET, Sercos III and Powerlink require dedicated MAC hardware
support in terms of FPGA or ASICs. The programmable real-time unit inside the
Industrial Communication Subsystem (PRU-ICSS), which exists as HW block inside
the Sitara processors family, replaces FPGA or ASICS by a single chip solution. A
firmware in the PRU-ICSS detects the type of industrial Ethernet protocol and loads
the appropriate industrial application during run-time into the Sitara processor. The
TIDEP0032 reference design describes the multi-protocol industrial Ethernet protocol
detection firmware for PRU-ICSS.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the
right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46,
latest issue, and to discontinue any product or service per JESD48,
latest issue. Buyers should obtain the latest relevant information
before placing orders and should verify that such information is current
and complete. All semiconductor products (also referred to herein as
“components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications
applicable at the time of sale, in accordance with the warranty in
TI’s terms and conditions of sale of semiconductor products. Testing
and other quality control techniques are used to the extent TI deems
necessary to support this warranty. Except where mandated by
applicable law, testing of all parameters of each component is not
necessarily performed.
TI assumes no liability for applications assistance or the design of
Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated
with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or
implied, is granted under any patent right, copyright, mask work
right, or other intellectual property right relating to any combination,
machine, or process in which TI components or services are used.
Information published by TI regarding third-party products or services
does not constitute a license to use such products or services or a
warranty or endorsement thereof. Use of such information may require
a license from a third party under the patents or other intellectual
property of the third party, or a license from TI under the patents or
other intellectual property of TI.
Reproduction of significant portions of TI information in TI data
books or data sheets is permissible only if reproduction is without
alteration and is accompanied by all associated warranties, conditions,
limitations, and notices. TI is not responsible or liable for such
altered documentation. Information of third parties may be subject to
additional restrictions.

Resale of TI components or services with statements different from
or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated
TI component or service and is an unfair and deceptive business
practice. TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for
compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its
applications, notwithstanding any applications-related information or
support that may be provided by TI. Buyer represents and agrees that
it has all the necessary expertise to create and implement safeguards
which anticipate dangerous consequences of failures, monitor failures
and their consequences, lessen the likelihood of failures that might
cause harm and take appropriate remedial actions. Buyer will fully
indemnify TI and its representatives against any damages arising out
of the use of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to
facilitate safety-related applications. With such components, TI’s
goal is to help enable customers to design and create their own
end-product solutions that meet applicable functional safety standards
and requirements. Nonetheless, such components are subject to these
terms.
No TI components are authorized for use in FDA Class III (or similar
life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as
military grade or “enhanced plastic” are designed and intended
for use in military/aerospace applications or environments. Buyer
acknowledges and agrees that any military or aerospace use of TI
components which have not been so designated is solely at the
Buyer’s risk, and that Buyer is solely responsible for compliance with
all legal and regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/
TS16949 requirements, mainly for automotive use. In any case of use
of non-designated products, TI will not be responsible for any failure to
meet ISO/TS16949.
