+86 1535940827532-Channel 24 VDC Digital Input FTA - Honeywell TDC 3000 / TPS Process Manager I/O
Honeywell MC-TDID12 51304441-175 is a thirty-two-channel 24 VDC digital input field termination assembly for Process Manager I/O. It terminates discrete DC field signals and connects them to the approved digital input processor.
Honeywell planning data identifies the 51304441-175 assembly with compression terminals, thirty-two inputs, CE status and conformal coating. The 24 VDC input design is not interchangeable with similarly named 120 VAC TDIA assemblies.
Before replacement, verify polarity, field supply, input thresholds, channel map, commons, cable, paired IOP, grounding and cabinet location. Test each input transition and diagnostic before returning the application to service.

Honeywell MC-TDID12 51304441-175 terminates 32 24 VDC digital input circuits and interfaces them with the approved Process Manager digital input processor.
Honeywell MC-TDID12 51304441-175 is designed for 24 VDC inputs; applying a different voltage class can create incompatibility or equipment damage.
Honeywell MC-TDID12 51304441-175 provides thirty-two input channels, but the channel map, commons, fusing and database assignment must match the installed system.
Honeywell MC-TDID12 51304441-175 uses compression, which must match the field plug, conductor preparation and cabinet arrangement.
A 24 VDC TDID assembly and a 120 VAC TDIA assembly are not direct substitutes; voltage class, isolation, IOP compatibility, wiring and safety requirements must all agree.
Before installing Honeywell MC-TDID12 51304441-175, isolate field power and verify polarity or line voltage, commons, fusing, cable, connector seating, grounding and the paired IOP.
Provide the complete Honeywell MC-TDID12 51304441-175 nameplate, voltage class, terminal photographs, companion IOP, cable, channel configuration, quantity and destination.
Send the complete Honeywell model, part number, revision, quantity, destination and nameplate photo. Identification details will be verified before availability and lead time are confirmed.
