HONEYWELL 2MLQ-RY2B Relay Digital Output Module – TDC/TPS DCS Series
When a relay output module fails mid-process in a continuous manufacturing environment, the consequences cascade instantly — actuators lose command signals, safety interlocks go blind, and operators face unplanned shutdowns that cost thousands per hour. The HONEYWELL 2MLQ-RY2B is the relay digital output module engineered to prevent exactly that scenario, delivering rock-solid discrete control signals to field devices across the most demanding industrial environments.
Within the HONEYWELL TDC-3000 / TPS (Total Plant Solution) DCS ecosystem, the 2MLQ-RY2B occupies a critical position as a relay-type digital output card, providing galvanically isolated relay contacts for controlling motors, solenoid valves, and on/off actuators. Its design reflects HONEYWELL’s decades of leadership in process automation — a platform trusted in refineries, chemical plants, and power generation facilities across more than 100 countries worldwide.
