Honeywell CC-TAIM01 51305959-175 PMIO LL Mux IOTA

Overview

The Honeywell PMIO LL Mux IOTA (Low Level Analog Input Multiplexer Input Output Termination Assembly) is a highly reliable terminal base designed to interface low-level field sensors—primarily thermocouples (TC) and resistance temperature detectors (RTD)—with the Honeywell Process Manager Input/Output (PMIO) and Experion systems. It acts as the physical wiring termination point, embedding specialized multiplexing circuitry to route high-density temperature data down to a centralized control module.
