Honeywell MC-TAOY22 51204172-175 Analog Output Module

Product Overview

This analog output module converts digital control signals into standard current outputs for field actuators. It drives valves, positioners, and recording instruments in Honeywell TDC 3000 systems. The MC-TAOY22 51204172-175 provides multiple isolated channels for precise analog control. Its robust design ensures accurate signal generation across varied process conditions. This module plays an essential role in closed-loop control and final element actuation.

Technical Specifications

The MC-TAOY22 51204172-175 measures 27.9 cm in height, 17.8 cm in depth, and 2.5 cm in width. It weighs approximately 0.85 kg, including all terminal connectors and hardware. This module draws 300 mA from the 24 VDC power supply under full load conditions. It features four isolated analog output channels with 14-bit resolution. Each channel provides a standard 4-20 mA current signal with a maximum load of 600 ohms. The output update rate measures 50 ms for all four channels simultaneously. The module offers 1500 VAC optical isolation between the backplane and field circuits. Each output includes short-circuit protection and open-loop detection capabilities. The front panel features LED indicators for power and per-channel output status.

Output Configuration and Signal Management

This module scales digital values linearly to the selected current output range. It supports both 4-20 mA and 0-20 mA output configurations for flexibility. The MC-TAOY22 51204172-175 allows individual channel configuration through system software. Users can set outputs to hold last value during communication loss events. The unit also performs automatic calibration to maintain accuracy over temperature changes.
