The Honeywell 51401491-100 (also called MU-TAMT02) is a low-level analog input multiplexer. It handles up to 16 thermocouple inputs efficiently. This module routes low-level analog signals to control systems for precise data acquisition. It commonly integrates with Honeywell’s Universal Control Network (UCN). Engineers typically use it in Field Termination Assemblies (FTA) to gather thermocouple data. The device supports panel or DIN rail mounting and connects via RS-485 or Ethernet, depending on system setup.
