HONEYWELL 2MLQ-TR4A Digital Output Module – TDC 3000 Series
Imagine a critical process line suddenly losing discrete output control — solenoid valves fail to actuate, motor starters go unresponsive, and safety interlocks can no longer be commanded. Without a functioning digital output module, an entire DCS-controlled production unit can grind to a halt within minutes, triggering costly unplanned downtime and potential safety incidents. The HONEYWELL 2MLQ-TR4A is the precision component that stands between your process and that scenario.
The 2MLQ-TR4A is a Digital Output Module engineered for the Honeywell TDC 3000 Distributed Control System — one of the most widely deployed DCS platforms in the global process industries. Within the 2MLQ I/O family, this module delivers reliable discrete output signaling to field devices, making it a foundational element in refinery, chemical, power generation, and pulp & paper automation architectures worldwide. Its continued availability as a spare and replacement part reflects the long operational lifecycles typical of TDC 3000 installations.
