Overview
The 7B Series of signal conditioners
feature small size, low cost and a wide
output voltage range for a variety of
applications including process control
and factory-floor environments. The
single-channel 7B modules accept inputs
from a range of transducers and are
fully rated over the extended -40°C to +
85°C industrial temperature range.
All 7B Series modules are rated for a
nominal power supply input of +24 DC;
and, for maximum flexibility, they will
accept supply voltages in the +14 V DC
to +35 V DC range.The input modules,
with the exception of the 7B21, provide
a high-level output voltage that is factory
configured for either the +1 to +5 V or 0
V to +10 V range. The 7B21 is a unity
gain, isolated input module with an
input/ output range of ±10 V. Output
modules are available that provide
either isolated current or isolated bipolar voltage output. Model 7B39 converts
either a +1 V to +5 V input to a 4 to 20
mA output or a 0 V to +10 V input to a
0 - 20 mA output. The input/output
ranges of the 7B39 are factory configured. The 7B22 is a unity gain module
that provides an isolated ±10 V output
signal. All modules have a universal
pin-out and may be readily hot-swapped
under full power without disrupting
field wiring.
Each module accepts analog transducer
signals and transfers them to a process
control or factory data collection system
without the inherent noise, non-linearity,
drift and extraneous voltages which frequently accompany the signals. The modules feature a maximum nonlinearity of
±0.02% and are factory calibrated to guarantee a maximum accuracy specification
of ±0.1%. The 7B Series offers up to 1500
V rms continuous common mode voltage

isolation and 120 V rms of field wiring
input protection. The power supplies
necessary to drive each of the individual
module’s input circuitry are internally
isolated, enabling the 7B Series modules
to offer true channel-to-channel isolation
of the input signals.
The modules directly accept analog signals from thermocouples, RTDs, current
loop powered transmitters, and other
process control signals. The 7B Series
modules amplify, linearize, isolate,
protect and convert the transducer output signals to standardized analog
inputs for high-level analog I/O subsystems. Four-, eight- and sixteen-channel
backplanes are available. Each backplane incorporates screw terminals for
easy power connections and field
wiring, and includes a 25-pin D-type
connector for interfacing the high-level
single-ended voltage outputs to the
user’s equipment. Gold-plated sockets
are provided on each channel of the
backplane to ensure the reliability of
each module’s electrical connection.
Each module is compact, hard potted
and identical in pinout. This allows you
to configure the modules in a mix-andmatch fashion on a 4-, 8- or 16-channel
backplane to meet the requirements of
each application.

a 26-pin male header connector. This
cable converts any 7B Series backplane
25-pin I/) connector to the 26-pin cable
connectors. The AC1315 cable (2 foot,
26-pin to 26-pin) connects the AC1234
26-pin connector to the AC1393. The
AC1234 is an optional universal interface board with a 26-pin I/O connector
and 26 I/O screw terminals. It accepts
the AC1315 cable directly. With the
AC1393 adapter cable, it connects to any
7B Series backplane, providing screw terminals for interconnecting to controller.
