Features:
- Bridge Between Thermocouple Field Wiring and xPM/Experion PMIO Systems
- Integrates Local Cold Junction Reference with Solid-State Channel Multiplexing
- Works Together with xPM and Experion PMIO in LLMUX2 Configurations
The MC-TAMT03 51309223-175 functions as the LLMUX2 Thermocouple (TC) Field Termination Assembly in a PMIO system, providing reliable thermocouple signal conditioning and termination for all channels within the module. It continuously processes incoming thermocouple signals through dedicated A/D converters per channel and distributes conditioned data through the single IOP interface to support accurate temperature monitoring of all connected field devices. Rapid open thermocouple detection is standard with the MC-TAMT03 51309223-175, and its improved loop resistance capability allows longer thermocouple wiring runs to the field without signal degradation. The MC-TAMT03 51309223-175 has made improvements in several areas over previous LLMUX FTA designs in addition to incorporating solid-state technology and on-board diagnostic capability within the PMIO system.
The MC-TAMT03 51309223-175 provides essential signal termination and conditioning functions common to the entire LLMUX2 assembly, and is a critical component of the temperature measurement path, directly affecting the proper, normal operation of the overall monitoring system. The MC-TAMT03 51309223-175 occupies the FTA position in the assembly and interfaces directly with the associated IOP module.
For replacement applications, the LLMUX2 system requires the MC-TAMT03 51309223-175 to replace legacy LLMUX FTAs that are no longer being manufactured. In addition to standard thermocouple signal handling, the MC-TAMT03 51309223-175 configuration also performs enhanced open thermocouple detection. The MC-TAMT03 51309223-175 executes diagnostics using the on-board circuitry specified in the FTA design. Using this method, the diagnostic system continually monitors the health of all channels. If the system detects that a thermocouple channel is no longer providing a valid signal (open circuit condition), it will report the fault within one second and enable rapid maintenance response.
The MC-TAMT03 51309223-175 HONEYWELL LLMUX2 Thermocouple (TC) Field Termination Assembly may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
