1. Basic Model Information Part Number: 51304477-100 Generic Model: MU-TAMR02 (LLMUX RTD FTA) Full Name: Low Level Analog Input Multiplexer Field Termination Assembly Applicable System: Honeywell TDC3000 / TPS UCN DCS Control System Matching Main Card: MU-LAI02 Low Level Analog Input IOP Card

Description

2. Product Function Description

This multiplexer FTA is specially designed for low-level weak analog signals of RTD temperature sensors and thermocouples. It multiplexes multi-channel millivolt-level tiny temperature signals and transmits them to the MU-LAI02 IOP main card for high-precision collection.

Equipped with compression spring quick-release terminals for fast on-site wiring; built-in multi-stage filtering and signal isolation circuits effectively suppress industrial electromagnetic interference and ground loop drift, ensuring accurate transmission of micro-temperature signals. It is widely used for multi-point temperature measurement in chemical, power and oil & gas process control sites.
