Honeywell 2MLR-AC13 Power Supply Module | 5VDC 8.5A

Technical Specifications Breakdown

Key parameters for the 2MLR-AC13 are listed below for quick reference:

Industry Applications

For example, in a chemical plant, the 2MLR-AC13 can power distributed control system (DCS) I/O cards, ensuring accurate data acquisition. In a manufacturing line, it can supply PLC modules that control robotic arms, where voltage fluctuations could cause misoperations. The built-in RUN contact provides a dry contact output (24VDC, 0.5A) that can signal a supervisory system about the health of the power supply, enabling proactive maintenance.

Installation & Setup Guidance

When installing the 2MLR-AC13, ensure the AC input is within the specified range (85V~132VAC) and frequency (47~63 Hz). Use cables with a cross-section of 0.75 ~ 2 mm². For secure termination, use clamped terminals RAV1.25-3.5 or RAV2-3.5. The input fuse is built-in and not replaceable by the user; if it blows, the module must be replaced. Mount the module in a clean, dry enclosure with adequate ventilation to maintain the 55℃ output power rating. Always disconnect power before making connections.

Maintenance & Reliability

To ensure long-term reliability, inspect the module periodically for dust accumulation, loose connections, or signs of overheating. The mechanical life of the RUN contact is 20 million operations, and the electrical life is 100,000 cycles at rated switching current, so it can handle frequent signaling. The module is designed for continuous operation, but we recommend checking the output voltage LED (green when normal) during routine walkthroughs. If the LED is off, verify input power and load conditions.

Compatibility & Integration

The 2MLR-AC13 is part of the Honeywell family of power supplies, designed to integrate with Honeywell control systems. It provides a clean 5VDC output, which is commonly required for digital logic circuits. The RUN contact output can be wired to a PLC input to monitor power status. The built-in input fuse is UL approved, ensuring compliance with North American safety standards. For specific compatibility with your existing system, consult your system integrator or contact AutoDCSTech for expert advice.

Selection Guide & Purchasing Advice

When selecting a power supply, consider your load current and voltage requirements. The 2MLR-AC13 delivers 8.5A at 5VDC, suitable for many small to medium control systems. If your system requires more current, you may need a higher-rated supply. At AutoDCSTech, we stock genuine Honeywell modules and provide technical support to help you choose the right part. We understand that downtime is costly, so we offer fast shipping and reliable service. Contact us today to check availability and lifecycle status of the 2MLR-AC13.

Troubleshooting & Common Issues

If the output voltage is missing, first check the input power source and ensure it is within the specified range. If the input is correct but the LED is off, the internal fuse may have blown; since it is not user-replaceable, the module must be replaced. If the output voltage is low, check for overloading or short circuits. The over current protection triggers between 9.3A and 17.0A, so if your load exceeds 8.5A, the module may shut down. Always verify that the load is within the rated output current. For persistent issues, consult the technical manual or contact AutoDCSTech for guidance.
