Product Introduction
The Honeywell 2MLR-AC23-CC Redundant Power Supply Module is a critical power management component within Honeywell’s advanced control systems. Designed to ensure continuous and stable operation of control hardware, the 2MLR-AC23-CC provides redundant AC-powered 24 VDC output for critical system modules such as controllers, I/O modules, and network devices.
The module is specifically engineered for industrial environments where loss of control power is unacceptable—power plants, chemical processing units, and large-scale automation systems. It features seamless switchover between primary and backup AC power inputs and high efficiency in DC conversion. With hot-swappable capability and intelligent monitoring, the 2MLR-AC23-CC significantly enhances system availability and operational safety.
