Foxboro I/A Series FBM237 P0914XS Isolated 8 Output Module

Here are the key features of the FBM237:

• Eight 20 mA dc analog output channels

• Each output channel is galvanically isolated

• Single or redundant modules

• Compact, rugged design suitable for enclosure in Class G3 (harsh) environments

• Termination Assemblies (TAs) for locally or remotely connecting field wiring to the FBM237 TA for use with Output Bypass Station to maintain outputs during maintenance operations

• 3-tier termination assembly for per channel internally and/or externally loop powered transmitters
