- Use FBM240 only for the documented FBM240 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
FBM240 is a Foxboro redundant discrete output module with readback designed for Foxboro DCS 200 Series field I/O.

- Compare every output demand with the monitored contact state
- Investigate channel BAD status before returning the load to service
- Verify field supply, fuse and contact condition during mismatch diagnosis
- Use firmware 1.40N or later for the newer fail-safe options
- Restore each channel's fallback value, hold mask and delay
- Test sustained or momentary output mode under an approved procedure
- Match relay or direct-output termination hardware to the load
- Keep direct DC loads within 60 VDC and 2 A
- Use suppression suitable for inductive loads and the selected TA
- Redundant solenoid and valve control with contact-state readback
- Relay-output control of AC or DC plant loads
- Direct 15-60 VDC discrete-output service with monitored demand state
