+86 1535940827532-Channel 120 VAC Digital Input FTA - Honeywell TDC 3000 / TPS Process Manager I/O
Honeywell MC-TDIA12 51304439-175 is a thirty-two-channel isolated 120 VAC digital input field termination assembly for Process Manager I/O. It terminates AC field status signals and interfaces them with the approved digital input processor.
Honeywell planning data identifies compression terminals, thirty-two inputs, CE status and conformal coating for the 51304439-175 assembly. The 120 VAC input class must not be confused with 24 VDC TDID termination hardware.
Before replacement, isolate field circuits and verify voltage class, channel map, commoning, fusing, cable, paired IOP, terminal torque and cabinet location. Test every input state and diagnostic after wiring checks.

Honeywell MC-TDIA12 51304439-175 terminates 32 120 VAC digital input circuits and interfaces them with the approved Process Manager digital input processor.
Honeywell MC-TDIA12 51304439-175 is designed for 120 VAC inputs; applying a different voltage class can create incompatibility or equipment damage.
Honeywell MC-TDIA12 51304439-175 provides thirty-two input channels, but the channel map, commons, fusing and database assignment must match the installed system.
Honeywell MC-TDIA12 51304439-175 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-TDIA12 51304439-175, isolate field power and verify polarity or line voltage, commons, fusing, cable, connector seating, grounding and the paired IOP.
Provide the complete Honeywell MC-TDIA12 51304439-175 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.
