20 Industrial Data Acquisition and
Control System encompasses more than 25
years of design excellence and quality in the
process control industry. The initial offering in
this high performance and highly flexible system
is a family of DIN rail mounted, programmable,
multi-channel, industrially rugged signal
conditioning input and output modules and
communication modules. Each I/O module has
a 1500Vrms isolation barrier between field-
side and system-side wiring, and some models
offer per-channel isolation. All field wiring ter-
minals are heavily protected against overload,
accidental connection of incorrect signals, and
ESD. Modules mount on the industry standard
35x7.5mm gull-wing DIN rail, and a backbone
mounts within the rail providing power and
communication interconnections between the
communication modules and each I/O module.
One communication module can interface to
up to 24 I/O modules to construct a system
with a maximum of 384 channels that fits
within a standard 19” instrumentation rack!
Processors within each module make this
distributed system extremely powerful.
The Modules:
• Communication Modules: Offered in
Ethernet, RS-232, RS-485, and USB with
host software interfaces to the system using
Modbus TCP or Modbus RTU protocol
• Analog Input Modules: Interface to a wide
range of standard industrial sensors and
equipment and offer up to 16 channels of
input, each of which can be independently
configured
- Process Voltage, Process Current &
Thermocouple Input Modules offer
8-channel differential input or 16-channel

single-ended input for precise measure-
ment of voltage and current signals; they
also offer 8-channel measurement of five
thermocouple types including accurate cold
junction compensation and linearization.
All channels are individually configurable
for range, alarm limits, and averaging.
- RTD Input Modules interface to 2-wire,
3-wire, and 4-wire sensors including five
RTD types and potentiometers. Modules
offer six channels, each configurable for
range, alarm limits, and averaging.
- Strain Gage Input Modules connect to
full bridge sensors, have narrow or wide
bandwidth filtering and offer four channels,
each configurable for range, alarm limits,
and averaging.
- Frequency Input Module accepts zero-
crossing and TTL signals with frequencies
of 500Hz to 100kHz and provides a DC
stimulus for contact sensors. This module
has four channels, each configurable for
range and alarm limits.
• Analog Output Modules: Process Current
and Voltage Output models drive valves,
perform other crucial process operations,
and provide up to eight channels of output
which can be independently configured
• Discrete Input/Output Modules: Provide
multiple channels of input and output per
module and offer advanced special
functions as well as alarm capability
The System Backbone resides within the
DIN rail used for module mounting and pro-
vides power to and interface between the
communication module and the I/O modules.
