Safety Notes
1.4 Safety Notes
Warning
Switch off the system prior to working on bus modules!
In the event of deformed contacts, the module in question is to be replaced, as
its functionality can no longer be ensured on a long-term basis.
The components are not resistant against materials having seeping and
insulating properties. Belonging to this group of materials is: e.g. aerosols,
silicones, triglycerides (found in some hand creams).
If it cannot be ruled out that these materials appear in the component
environment, then additional measures are to be taken:
- installation of the components into an appropriate enclosure
- handling of the components only with clean tools and materials.
Attention
Cleaning of soiled contacts may only be done with ethyl alcohol and leather
cloths. Thereby, the ESD information is to be regarded.
Do not use any contact spray. The spray may impair the functioning of the
contact area.
The WAGO-I/O-SYSTEM 750 and its components are an open system. It
must only be assembled in housings, cabinets or in electrical operation
rooms. Access must only be given via a key or tool to authorized qualified
personnel.
The relevant valid and applicable standards and guidelines concerning the
installation of switch boxes are to be observed.
ESD (Electrostatic Discharge)
The modules are equipped with electronic components that may be destroyed
by electrostatic discharge. When handling the modules, ensure that the
environment (persons, workplace and packing) is well grounded. Avoid
touching conductive components, e.g. gold contacts.
1.5 Scope
This manual describes the Analog Input Module 750-469 (/xxx-xxx)
2 AI Thermocouple of the modular WAGO-I/O-SYSTEM 750.
Handling, assembly and start-up are described in the manual of the Fieldbus

Description
2.1.1.3 Description
The 750-469 analog input module and its 750-469/xxx-xxx variations allow
thermocouples be measured in the field. It can also be used to measure
voltages (mV).
Depending on the operating mode, the voltage value is converted to a
temperature or directly send out by the module. A microprocessor within the
module is used for converting and linearizing the measured voltage value into
a numeric value proportional to the temperature of the selected thermocouple.
The operating mode of the 750-469/003-000 variation can be set by
parameterization using the WAGO-I/O-CHECK 2 start-up and diagnostic
tool (Item No.: 759-302). The default setting is thermocouple of type K.
The operating mode of the 750-469 basic module described in this manual is
for a type K thermocouple.
The analog module has two input channels allowing the direct connection of
two thermocouples.
For example, two thermocouples can be connected either to +TC1 and -TC1 or
to +TC2 and -TC2.
The shield (screen) is directly connected to the DIN rail. A capacitive
connection is made automatically when snapped onto the DIN rail.
An optocoupler is used for electrical isolation between the bus and the field
side.
The operational readiness and trouble-free internal data bus communication of
the channels are indicated via a green function LED. Broken wire, overrange
or underflow of the measuring range is indicated via a red Error LED.
Any configuration of the input modules is possible when designing the
fieldbus node. Grouping of module types is not necessary.
Attention
This module has no power contacts. For field supply to downstream I/O
modules, a supply module will be needed.
The analog input module 750-469 and its variations can be used with all
couplers/controllers of the WAGO-I/O-SYSTEM 750 (except for the economy
types 750-320, -323, -324 and -327).

System Description
2.1.1.7 Process Image
Some fieldbus systems can process input channel status information by means
of a status byte.
This status byte can be displayed via the starting tool WAGO-I/O-CHECK 2.
However, processing via the coupler / controller is optional, which means that
accessing or parsing the status information depends on the fieldbus system.
Attention
The representation of the process data of some I/O modules or their variations
in the process image depends on the fieldbus coupler/-controller used. Please
take this information as well as the particular design of the respective
control/status bytes from the section "Fieldbus Specific Design of the Process
Data" included in the description concerning the process image of the
corresponding coupler/controller.

2.1.1.7.1.2 Data Format with Status Information for S5 – FB 250 in Data Word
For the 750-469/000-200 and 750-469/000-206 variations, the temperature
values of the sensors are represented with a resolution of 1 digit per 0.125 °C
within a word (16 bits). Thus, 0 °C corresponds to the numeric value 0x0000
and 100 °C to 0x0320 (dec. 800).
Diagnostic information is indicated in the 3 low bits.

Adjustable 750-469/003-000 Variation
2.1.1.8 Adjustable 750-469/003-000 Variation
The operating mode of the 750-469/003-000 variation can be parameterized
using the WAGO-I/O-CHECK 2 start-up and diagnostic tool (Item No.: 759302).
The default setting is type K thermocouple. In this operating mode, the
module has the same behavior and process values as the 750-469 basic
module.
The parameter dialog box of WAGO-I/O-CHECK 2 contains select boxes
that are used to set this module.

Examples of Connection
2.1.1.9 Examples of Connection
When connecting the thermocouples, good grounding practices must be
guaranteed between the machine and the sensors that are connected to the
module. Insufficient grounding can lead to common mode voltages, which
may distort the measuring result.
Due to the differential inputs, grounded and ungrounded thermocouples can be
connected in the following ways:
With grounded thermocouples, the common ground (M) can be connected to
the screen (S) using an external bridge so that common mode interferences can
be eliminated (see figure below).

With ungrounded thermocouples, the common ground (M) can be connected
both to the TC input and to the screen (S), if required, using an external bridge
so that common mode interferences can be eliminated (see figure below).
