The Honeywell MC-TAOX12 (Part Number 51304441-175) is a 16-channel Analog Output Field Termination Assembly (FTA) engineered for the High-Performance Process Manager (HPM), TDC 3000, and Experion PKS control platforms. This module serves as a critical interface between the I/O processors and field-level instrumentation, delivering precise 4–20 mA DC signals to control valves, actuators, and I/P transducers.
Distinguished by the "MC" prefix, this board features a high-grade conformal coating designed to withstand corrosive or high-humidity industrial environments. It supports full redundancy, allowing for dual I/O processor connections to ensure zero-point failure and continuous process control during hardware maintenance or failover events. Its industrial-grade construction ensures long-term signal stability across extensive cable runs in complex automation infrastructures.
