Honeywell 2MLR-AC22 Power Supply Module

The Honeywell 2MLR-AC22 is a high-capacity power supply module designed for MasterLogic-200 PLC system racks. It accepts an AC 220V grid input and delivers regulated DC 5V and secondary rail outputs to sustain reliable CPU and I/O module operation.

Power Conversion and Input Characteristics

The module operates from a nominal input voltage of 220V AC across an allowable range of 176V to 264V AC at 50/60 Hz (47 to 63 Hz). It handles a maximum input power of 176 VA or 72 W while keeping peak inrush current at 80A or lower. An internal built-in fuse protects the circuit and is non-user-replaceable.

Output Power and Protection

The primary output provides a regulated DC 5V with a +/-2% tolerance, supplying an output current of 8.5A and 46.75W of power at 55 deg C. Overcurrent protection engages within a range of 9.3A to 17.0A to prevent excessive load conditions.

System Signaling and Diagnostics

An integrated RUN contact relay output provides remote status monitoring, rated at 24V DC and 0.5A with a minimum switching load of 5V DC and 1mA. The relay achieves an Off-to-On response time of 10ms or less and an On-to-Off response time of 12ms or less. Mechanical life expectancy exceeds 20 million cycles, while electrical life at rated switching current exceeds 100,000 cycles. A front-panel LED illuminates when the output voltage is normal.
