SCM5B Modules

Dataforth Corporation offers cost-effective, isolated industrial signal
conditioning modules. The SCM5B analog modules are form, fit, and functional
equivalents to similar products from other manufacturers. The product line
includes a complete selection of backpanel options, interface cables, racks,
fuses, jumpers, power supplies, and other accessory items.

Improved SCM5B Analog Modules

Each SCM5B module provides a single channel of isolated analog input or
output. Input modules interface to all types of external sensors. The modules
filter, isolate, amplify, and convert the input signal to a high-level analog voltage
output. The output modules accept a high-level analog voltage signal from a host
system, then buffer, isolate, and amplify before providing a process current or
voltage output to field devices. Over 250 different SCM5B modules are available
encompassing a wide selection of isolated analog input and output functions.
Analog inputs include voltage and current in narrow and wide bandwidths,
thermocouple, RTD, accelerometer, potentiometer, strain gage, frequency and
2-wire transmitter. Custom I/O ranges are also available. All modules are CSA
certified and FM approved for safe operation in Class I, Division 2, Groups A, B,
C, and D hazardous environments. They are also CE and ATEX compliant.

Accessories include addressable and non-addressable single, dual, 8- and 16-
channel backpanels which include on-board temperature sensors and cold
junction thermocouple compensation, power supplies, mounting racks,
interface cables, and evaluation boards.

Dataforth SCM5B modules offer several advantages when compared with
competitive parts, while maintaining equivalent price:
• 50 times better noise rejection by using a 6-pole filter with 95dB
NMR, versus a 3-pole filter with 60dB NMR
• Lower output noise
• True 3-way isolation
• 20dB better CMR of noise spikes than competing models
