+86 1535940827516-Channel LLMux Thermocouple FTA - Honeywell TDC 3000 / TPS Process Manager I/O
Honeywell MC-TAMT03 51309223-175 is a sixteen-channel low-level multiplexer thermocouple field termination assembly for Process Manager I/O. It terminates thermocouple signals and routes them to the compatible low-level multiplexer I/O Processor.
Honeywell hardware planning data identifies the 51309223-175 assembly with compression terminals, sixteen input channels, Size B mounting and a CE-compliant conformally coated construction. These details distinguish it from RTD and second-generation LLMUX2 termination assemblies.
Before replacement, verify thermocouple type, cold-junction arrangement, polarity, extension wire, cable, paired IOP, terminal map and configured range. Commission each input with an approved temperature or millivolt reference.

Honeywell MC-TAMT03 51309223-175 terminates sixteen thermocouple circuits and routes their low-level signals to the compatible multiplexer I/O Processor; the installed sensor types, cable and channel configuration must match the assembly.
Honeywell MC-TAMT03 51309223-175 belongs to the first-generation LLMux thermocouple arrangement, so the approved cold-junction method and companion hardware must be confirmed from the installed configuration.
Confirm thermocouple type, polarity, extension-wire material, shield grounding, terminal allocation and the absence of unintended copper junctions before fitting Honeywell MC-TAMT03 51309223-175.
An RTD termination assembly cannot be substituted for Honeywell MC-TAMT03 51309223-175 merely because the connector or mounting size appears similar; sensor interface, compensation method, cable and IOP compatibility are different.
Honeywell MC-TAMT03 51309223-175 must match the approved low-level multiplexer IOP, interface cable, field connectors, cabinet mounting and engineering database used by the installed Process Manager system.
Commission Honeywell MC-TAMT03 51309223-175 by checking cold-junction behavior, polarity, open-sensor diagnostics and each configured channel with an approved millivolt or temperature reference.
Provide the complete Honeywell MC-TAMT03 51309223-175 nameplate, hardware revision, thermocouple types, companion IOP, cable, connector arrangement, 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.
