Honeywell 51404106-175 RHMUX Analog Input Multiplexer

The Honeywell 51404106-175 (MC-GRMT01) is a specialized remote/local analog input multiplexer designed for processing low-level analog signals in industrial automation environments. It offers integrated signal conditioning and conversion across up to 16 input channels, incorporating a local Cold Junction Reference (CJR) to ensure accurate thermocouple temperature measurements.

Functional Role and Signal Conditioning

This multiplexer handles low-level process signals, converting and conditioning multi-channel inputs before they reach the control system. The inclusion of a local CJR directly at the terminal junction compensates for thermocouple reference temperatures, maintaining measurement precision in demanding industrial installations.
