Honeywell MU-TAOY22 – Analog Output Module | TotalPlant Solution (TPS) DCS Platform
Engineering Background
The Honeywell MU-TAOY22 is a precision analog output module engineered for the TotalPlant Solution (TPS) Distributed Control System — Honeywell’s flagship process automation platform widely deployed across refining, petrochemical, power generation, and continuous manufacturing industries. Designed to interface directly with field actuators and control valves, this module delivers reliable 4–20 mA analog output signals with high-resolution conversion, ensuring accurate process variable control in safety-critical environments.
Product Positioning
As a core I/O component within the TPS architecture, the MU-TAOY22 serves procurement engineers and plant maintenance teams seeking verified replacement modules for aging DCS infrastructure. Konmask.com supplies this module from certified surplus and refurbished channels, providing a cost-effective alternative to OEM lead times without compromising functional integrity.

System Architecture & Signal Flow
The MU-TAOY22 resides in the TPS I/O Link subsystem, receiving setpoint commands from the High-Performance Process Manager (HPM) or Application Module (AM) via the Local Control Network (LCN). Each output channel independently drives a 4–20 mA current loop to field-mounted control valves, variable frequency drives (VFDs), or positioners. The module’s onboard microprocessor performs real-time D/A conversion and loop integrity monitoring, reporting channel health back to the operator station via the Universal Control Network (UCN) gateway.
Signal Flow: HPM/AM → LCN Bus → MU-TAOY22 DAC → 4–20 mA Field Loop → Control Valve / Actuator
