Model: 51204156125 (Standard Number: 51204156-125)

Brand: Honeywell

Product Type: UCN Digital Output FTA Terminal Board (Digital Output FTA)

Product Alias: MU-TDOY62

I. Product Overview

51204156-125 (MU-TDOY62) is a standard 32-channel 24V digital output field terminal component (FTA - Field Termination Assembly) of the UCN (Universal Control Network) network in Honeywell's TDC 3000 / PlantScape DCS system. As an interface between the control system and field actuators (such as solenoid valves, indicator lights, relays), it is responsible for outputting system control signals to the field equipment, and is widely used in process control fields such as petroleum, chemical, and power.
