- Use FBM218 only for the documented FBM218 channel function
- Confirm the electronic-module order number, termination hardware and cable before replacement
- Preserve field wiring, channel configuration, diagnostics and redundancy state before removal
FBM218 is a Foxboro hart communication redundant output module designed for Foxboro DCS 200 Series field I/O.
Foxboro FBM218 is an eight-channel redundant 4-20 mA output module with HART communication for Foxboro DCS field devices. FBM218 is the official functional model and RH922VW is its current exact module part number; RH916QD is a separate redundant adapter.
Before installation or replacement, verify the complete nameplate, companion hardware, termination assembly, cable, signal limits, field wiring, saved configuration and supported system environment.
Availability, condition, price, and shipping time for FBM218 are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Use HART version 5, 6 or 7 devices in point-to-point service
- Keep each loop within the documented distance and burden limits
- Do not enable HART burst mode because FBM218 does not support it
- Install the master/tracker pair with the RH916QD redundant adapter
- Preserve adjacent module roles and the common termination identity
- Verify output continuity and HART communication during approved transfer testing
- Keep the output burden at or below 750 Ω
- Account for barriers, cable resistance and field-device voltage drop
- Check channel isolation, polarity and field wiring before energization
- Redundant 4-20 mA valve and actuator positioning
- HART-enabled process field-device output control
- High-availability analog output service requiring continued operation after a single detected module failure
