Honeywell 2MLR-AC12 Power Supply Module

The 2MLR-AC12 is a redundant AC power supply module designed for the Honeywell MasterLogic-200 PLC system. It delivers a stable 5 VDC output to critical automation hardware, featuring built-in fault protection, relay status outputs, and front-panel LED indicators to support continuous industrial operation.

Input and Output Performance

The module accepts a rated input voltage of 110 VAC with an operating range of 85 to 132 VAC at 50 or 60 Hz. It regulates the output to 5 VDC with a 2 percent tolerance, providing up to 5.5 A of output current and 27.5 W of power at an ambient temperature of 55 deg C.

Protection and Relay Status

Built-in overcurrent protection activates between 6.0 A and 13.0 A to safeguard connected components. The unit also includes a RUN contact relay output rated at 24 VDC and 0.5 A, featuring a minimum switching load of 5 VDC at 1 mA and a response time of under 10 ms for ON transitions.
