Honeywell MasterLogic-200 2MLR-AC22 | PLC AC Power Supply Module

Product Description

The Honeywell 2MLR-AC22 is an AC-input power supply engineered specifically for the MasterLogic-200 PLC platform. It converts industrial 200–240 VAC line power into regulated low-voltage DC required by the PLC CPU, communication cards, and I/O backplanes. Designed for continuous operation in control cabinets, this module supports redundant power architectures and ensures consistent system uptime in mission-critical applications.

With a compact rack-mount format and integrated protection circuitry, the 2MLR-AC22 delivers dependable performance in electrically noisy and thermally demanding environments.
