Honeywell 2MLR-DC42-CC DC Power Supply Module – Experion PKS / TotalPlant Solution Series
When a power supply module fails in a live DCS environment, the consequences are immediate and severe — process shutdowns, unplanned downtime, and potential safety incidents that can cost tens of thousands of dollars per hour. In high-stakes industries such as oil & gas, petrochemicals, and power generation, the integrity of every control system component is non-negotiable. The Honeywell 2MLR-DC42-CC DC Power Supply Module is the critical link that keeps your Experion PKS or TotalPlant Solution (TPS) control system energized, stable, and fully operational.
The 2MLR-DC42-CC belongs to Honeywell’s proven Multiloop Rack (MLR) power supply family, engineered specifically for the demanding requirements of the Experion PKS and legacy TotalPlant Solution DCS platforms. As one of the most widely deployed DC power supply modules in global process automation infrastructure, this part is trusted by plant engineers and system integrators across more than 100 countries. Its robust design, redundancy support, and compatibility with Honeywell’s broader control architecture make it an indispensable component for any facility running Honeywell DCS technology.
