- Use RH922VW 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
RH922VW is a Foxboro fbm218 hart communication redundant output module designed for Foxboro DCS 200 Series field I/O.
Foxboro RH922VW is the current exact module part number for the eight-channel FBM218 redundant 4-20 mA/HART output module. RH922VW is not a sibling model: the official FBM218 PSS lists RH922VW as the current exact module part number for FBM218.
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 RH922VW are confirmed during quotation.

- Use RH922VW as the exact electronic-module order number
- Map the module function to FBM218 in the control database
- Keep RH916QD and termination hardware out of the module identity
- Use HART version 5, 6 or 7 point-to-point devices
- Limit communication to the documented 1200-baud master/slave mode
- Check distance, burden and barriers for every field loop
- Install the documented master/tracker module pair
- Use the RH916QD redundant adapter with the approved termination
- Verify loop continuity and diagnostics during controlled transfer
- 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
