Honeywell 2MLR-AC13 Redundant Power Supply Module AC 110V 8.5A

Product Overview

The Honeywell 2MLR-AC13 is a redundant power supply module for the MasterLogic-200R (ML200R) high-availability PLC system. It accepts AC 110V input and delivers regulated DC 5V at 8.5A to power the CPU, I/O modules, and communication modules in the redundant rack. Designed for critical applications where downtime is unacceptable, it features active-active redundancy with automatic failover, ensuring continuous operation even if one power supply fails or is removed for maintenance.

Key Specifications

• Product Type: Redundant Power Supply Module
• Series: MasterLogic-200R (Redundant)
• Input Voltage: AC 110V (85–132V range)
• Output Voltage: DC 5V (regulated)
• Output Current: 8.5A
• Redundancy Type: Active-Active (parallel load sharing)
• Switchover Time: Zero (hot-standby, no interruption)
• Efficiency: >85%
• Protection: Overvoltage, overcurrent, short-circuit, thermal shutdown
• Run Contact: Built-in relay contact for power status indication
• Hot-Swappable: Yes — replace without stopping the process
• Dimensions (W x H x D): 122 mm x 35 mm x 100 mm
• Weight: Approx. 0.45 kg
• Operating Temperature: 0°C to +55°C
• Certifications: CE, RoHS

Features & Benefits

• Active-active redundancy — two 2MLR-AC13 modules share the load equally; if one fails, the other instantly assumes 100% load with zero switchover time
• 8.5A high capacity — supports fully loaded 12-slot redundant racks with CPU, communication, and high-density I/O modules without additional power supplies
• Hot-swappable design — failed power supplies can be replaced while the system continues to run, eliminating planned shutdowns for maintenance
• Built-in run contact — dry relay contact interfaces directly with the PLC diagnostic input or building management system for remote power status monitoring
• Comprehensive protection — overvoltage, overcurrent, short-circuit, and thermal shutdown safeguards protect the power supply and downstream modules from electrical faults

Typical Applications

• Power plant turbine control and burner management systems
• Petrochemical refinery safety instrumented systems (SIS)
• Pharmaceutical batch reactor control with FDA validation requirements
• Water treatment plant critical pump and valve control
• Steel mill continuous casting and rolling mill automation
• Any application requiring SIL-rated or high-availability control

Installation Guide

1. Verify AC input voltage — confirm your site provides AC 110V (85–132V). If your site uses AC 220V, select 2MLR-AC23 instead.
2. Install in redundant power slot — the 2MLR-AC13 installs in the dedicated power supply slots of the ML200R main base (2MLR-M02P or 2MLR-M06P). Install two modules for full redundancy.
3. Connect AC input — wire AC 110V to the L and N terminals of both power supplies through independent circuit breakers.
4. Connect ground — bond the PE terminal to the cabinet earth bus using 2.5 mm² green/yellow wire.
5. Verify run contacts — wire the built-in relay contacts to the PLC diagnostic inputs or alarm annunciator panel.
6. Test failover — with the system running, remove one power supply and confirm the second maintains 5V output and the CPU continues normal operation.

FAQ

Q: What is the difference between 2MLR-AC13 and 2MLR-AC12?
A: The 2MLR-AC13 provides 8.5A output capacity for heavily loaded racks. The 2MLR-AC12 provides 5.5A output capacity. Both accept AC 110V input. Choose AC13 for full 12-slot racks; choose AC12 for smaller 2-slot or 6-slot configurations.

Q: What is the difference between 2MLR-AC13 and 2MLR-AC23?
A: The 2MLR-AC13 accepts AC 110V input. The 2MLR-AC23 accepts AC 220V input. Both provide 8.5A at 5V DC. Choose based on your local mains voltage.

Q: Can I use this in a non-redundant ML200 system?
A: No. The 2MLR-AC13 is designed exclusively for the ML200R redundant rack. Non-redundant ML200 systems use 2MLP-ACF1, 2MLP-ACF2, or 2MLP-DC42 power supplies.

Q: What happens if both power supplies fail?
A: The ML200R CPU has a supercapacitor backup that maintains memory and real-time clock for several minutes during total power loss, allowing graceful shutdown or alarm state transition.

Selection Tips

• Select 2MLR-AC13 for AC 110V sites with high-capacity redundant racks (8–12 slots fully populated).
• For AC 220V sites, choose 2MLR-AC23 (8.5A) or 2MLR-AC22 (5.5A).
• For DC 24V battery-backed systems, select 2MLR-DC42 (7.5A redundant DC input).
• Always install two power supplies per rack to achieve true redundancy — a single supply provides no fault tolerance.
• Size your power budget carefully — a fully loaded 12-slot rack with high-density I/O and communication modules can exceed 5.5A, requiring the 8.5A AC13 model.
