Honeywell MC-TAOY22 Part No. 51204172-175 Digital Analog Output Module 4-20mA
The Honeywell MC-TAOY22, with official part number 51204172-175, is a high-density analog output terminal module designed for use in Honeywell Experion® PKS (Process Knowledge System) and Safety Manager control platforms. This rugged I/O interface module provides 16 isolated analog output channels for precise control of field devices such as control valves, variable frequency drives (VFDs), positioners, and actuators in continuous-process industries—including oil & gas, refining, chemical processing, power generation, and water treatment.
Engineered for reliability and ease of maintenance, the MC-TAOY22 features removable terminal blocks, LED status indicators per channel, and robust galvanic isolation between field wiring and the system backplane. It supports standard industrial signals including 4–20 mA and 1–5 V DC, making it compatible with a wide range of final control elements. When used with Honeywell’s redundant I/O carriers (e.g., MC-PAx series), the module supports hot-swap capability and seamless integration into fault-tolerant architectures—minimizing downtime during maintenance or upgrades.
