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.
