Honeywell TC-1AH161

The Honeywell TC-1AH161 (often referenced as TC-IAH161) is a 16-channel high-level analog input module designed for the Experion PKS C-Series I/O system, compatible with C200 and C300 controllers. Its core function is to acquire high-precision analog signals—such as 0-20 mA, 4-20 mA, and ±10 V—from field transmitters and sensors, converting them into digital data for process monitoring and control.
