The Honeywell 2MLR-AC13 Redundant Power Supply Module is an integral component of Honeywell’s industrial control systems, specifically designed for use within critical process automation environments. Engineered to provide reliable and uninterrupted power to controller modules and field devices, it ensures system resilience even in the event of a power supply failure.

The module supports redundant operation, which means two power supplies can operate in parallel to guarantee continuous operation. In the case that one power unit fails, the second one automatically takes over without causing any process disruption. The 2MLR-AC13 is typically deployed within Honeywell’s Experion PKS and C300 controller environments and plays a pivotal role in mission-critical applications where power stability is non-negotiable.
