+86 1535940827532-Channel 120 VAC Digital Input FTA - Honeywell TDC 3000 / TPS Process Manager I/O
Honeywell MC-TDIA72 51303930-150 is a thirty-two-channel isolated 120 VAC digital input field termination assembly for Process Manager I/O. It accepts AC field-status wiring through removable screw-terminal connections.
Honeywell planning information identifies the 51303930-150 assembly as the non-CE TDIA72 variant with thirty-two inputs and conformal coating. Its removable screw-terminal construction differs from the compression-terminal TDIA12 assembly.
Verify field voltage, terminal plug, channel commoning, fusing, cable, paired IOP, cabinet space and safety isolation before replacement. Commission all input states and diagnostics under the approved site procedure.

Honeywell MC-TDIA72 51303930-150 terminates 32 120 VAC digital input circuits and interfaces them with the approved Process Manager digital input processor.
Honeywell MC-TDIA72 51303930-150 is designed for 120 VAC inputs; applying a different voltage class can create incompatibility or equipment damage.
Honeywell MC-TDIA72 51303930-150 provides thirty-two input channels, but the channel map, commons, fusing and database assignment must match the installed system.
Honeywell MC-TDIA72 51303930-150 uses removable screw terminals, 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-TDIA72 51303930-150, isolate field power and verify polarity or line voltage, commons, fusing, cable, connector seating, grounding and the paired IOP.
Provide the complete Honeywell MC-TDIA72 51303930-150 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.
