General Description
OMEGA® OM5 Series Isolated Signal Conditioning Modules are low cost,
high performance, plug-in signal conditioners. Each OM5 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 115 different OM5 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, 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.
Accessories include: addressable and non-addressable single, dual, eight
and 16 channel backpanels, available with on-board temperature sensors
and cold junction thermocouple compensation; power supplies; mounting
racks; interface cables, and evaluation boards.
OM5 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 three-pole filter with 60dB NMR; • Lower output noise
• True 3-way isolation • CMR of noise spikes measures 20dB better
than competing models.
