Honeywell MC-TDOY22 51204162-175 Digital Output Termination Assembly
The Honeywell MC-TDOY22 (51204162-175) Digital Output Termination Assembly is a key DCS component (for TDC 3000). It outputs control signals to field actuators (valves, relays), supports multi-channel (typically 16-ch) 24VDC, simplifies wiring, ensures stable signal transmission, and suits industrial process control.
The Honeywell MC-TDOY22 (Part Number: 51204162-175) is a high-reliability digital output module belonging to Honeywell’s Experion PKS Control System I/O portfolio, specifically designed for integrating with controllers like the C300 to deliver precise switch-control signals to field devices. Its core function is to receive digital control commands (e.g., "on/off" or "enable/disable" signals) from the central controller, then convert and output these commands as stable, industry-standard digital signals (typically relay or solid-state outputs) to drive critical field actuators—such as solenoid valves, motor contactors, indicator lights, and process interlock switches—for regulating industrial processes (e.g., opening/closing valves in fluid control, activating alarms in safety loops, or starting/stopping auxiliary motors). It features multiple independent channels (commonly 8 channels for this model) that can be individually configured for different output types or fault-safe behaviors, along with built-in channel-level diagnostics (e.g., detecting open circuits, short circuits, or output overloads) and galvanic isolation to prevent signal interference or fault propagation in harsh industrial environments. Additionally, it seamlessly integrates with Honeywell’s Experion PKS software for centralized configuration, monitoring, and maintenance, and supports optional hot-swap capability to minimize downtime during module replacement, ensuring continuous operation of process control loops in industries like oil & gas, chemical processing, and power generation.
