Honeywell MC-TAOY22 51204172-175 – 16-Channel Isolated Analog Output Module for Experion PKS

The Honeywell MC-TAOY22 51204172-175 is a 16-point, isolated, 4-20 mA analog output module engineered to deliver precise, high-resolution current signals from any Experion PKS C300 or Safety Manager controller. Each channel is independently isolated to 250 Vrms channel-to-channel and 500 Vrms channel-to-ground, eliminating ground-loop noise and allowing direct drive of actuators, control valves, and variable-speed drives in harsh industrial environments.

Built for Series C I/O racks, the module accepts 16-bit DAC resolution across a 0-22 mA working span (default 4-20 mA) with <0.1 % full-scale accuracy and <0.05 % repeatability. Hot-swap design lets technicians replace the card without powering down the rack; auto-keying prevents accidental insertion of the wrong module type. A redundant 24 V dc field power loop (18-30 V dc) is distributed internally to all 16 channels, so external loop supplies are optional.

On-board diagnostics include open-loop, short-circuit, and over-temperature detection, each reported to the host controller via HART pass-through and front-panel LEDs. Spring-cage terminals accept 0.2-2.5 mm² conductors and lock for vibration resistance; removable terminal blocks allow pre-wiring for faster change-outs. The conformally-coated board operates from -40 °C to +70 °C and carries UL 508, CE, ATEX Zone 2, and IECEx certifications.

Typical applications include refinery distillation columns, offshore separator skids, pharmaceutical batch reactors, and power-generation balance-of-plant systems.
