Foxboro FBM237 P0914XS 0 to 20 mA Output Module

Foxboro FBM237 P0914XS0 to 20 mA Output Module

Description

The FBM237 contains eight 0-20 mA analog output channels. In situations where control system reliability is important, the FBM237 may have a redundant module installed. This permits all eight outputs to maintain operation in the presence of a single fault and during the time that the suspect module is removed and replaced. The 0-20 mA signals are electrically compatible with HART® field devices.

The FBM237, 0 to 20 mA Output Module contains eight channels.The outputs are galvanically isolated from other channels and ground. The module can be used as a single unit, or as a redundant pair (two FBM237s).

When used as a redundant pair, field output signals are wired to one common termination assembly. Each module in the pair independently holds the output(s) at its specified output value(s).

Features

• 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
