Honeywell MU-TDOR12 51304443-100 Digital Relay Output Board

Description

The MU-TDOR12 is a 16-channel relay-based digital output Field Termination Assembly (FTA) designed for Honeywell’s TDC 3000 and TPS (TotalPlant Solution) systems. It provides isolated switching for field devices that require 120 VAC or 125 VDC signals, making it ideal for controlling power circuits in demanding industrial environments.
