Honeywell 2MLR-AC13-CC – AC Power Supply Module | 2MLR Safety Relay Platform
Engineering Background
The Honeywell 2MLR series is a modular safety relay platform engineered for machine safety and process control applications requiring IEC 61508 / EN 954-1 compliance. The 2MLR-AC13-CC is the dedicated AC-input power supply module that energizes the 2MLR backplane, converting line-voltage AC power into the regulated DC bus required by all logic, I/O, and communication modules in the rack.
Product Positioning
Designed for procurement engineers specifying safety-rated power infrastructure in automotive assembly, packaging machinery, material handling, and process industries. The 2MLR-AC13-CC eliminates the need for an external 24 VDC power supply, simplifying panel design and reducing BOM complexity while maintaining full CE / UL certification.

- Compact Form Factor – Narrow-profile module maximizes rack density; compatible with full 2MLR module ecosystem
System Architecture & Signal Flow
The 2MLR-AC13-CC occupies the leftmost slot of the 2MLR base/rack assembly. AC line voltage (L/N/PE) is wired directly to the module’s screw terminals. Internally, the switching power supply converts AC to a regulated 24 V DC bus distributed across the backplane connector to all downstream 2MLR modules (logic relays, I/O expanders, fieldbus gateways). The module provides LED status indication for power-good and fault conditions. No external DC wiring between the PSU and other modules is required — all power distribution is handled via the backplane bus.
Typical rack order: [2MLR-AC13-CC] → [2MLR Logic Module(s)] → [2MLR I/O Expander(s)] → [2MLR Communication Module]

Technical FAQ
Q: Can the 2MLR-AC13-CC power a full 2MLR rack with multiple modules?
A: Yes. The 1.3 A / 24 VDC output is sized to power the standard 2MLR base plus multiple logic and I/O modules. Consult the 2MLR system manual for maximum module count per power supply.
Q: Is this module compatible with 2MLR-DC input variants?
A: No. The AC13 variant accepts AC input only. For 24 VDC input applications, the corresponding DC power supply module (e.g., 2MLR-DC13-CC) is required.
Q: What is the “CC” suffix in the part number?
A: “CC” typically denotes the connector/configuration variant within the 2MLR family. Always order by full part number to ensure exact fit.
Q: Does this module require any configuration or firmware?
A: No. The 2MLR-AC13-CC is a passive power supply module with no programmable parameters. It is plug-and-play within the 2MLR rack.
Q: Can I use this module outside the 2MLR rack as a standalone 24 VDC power supply?
A: Not recommended. The output is designed to feed the 2MLR backplane bus. For standalone 24 VDC applications, use a standard DIN rail PSU.
