Allen Bradley 1606-XLP15E Power Supply

Allen Bradley 1606-XLP15E Power Supply

Configured for regulated low‑power DC output in industrial control enclosures, the Allen Bradley 1606-XLP15E (1606-XLP15E power module) provides direct 24 VDC supply for PLC, HMI, and sensor loads within Compact and ControlLogix‑adjacent architectures.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

Although the 1606‑XLP15E is a standalone power module, its regulated output directly affects deterministic network behavior in Allen Bradley PLC systems. Stable DC supply prevents voltage sag during EtherNet/IP cyclic bursts and reduces backplane noise coupling. The module’s efficiency profile (85–86%) and low ripple (<50 mVpp) support predictable I/O density scaling, ensuring analog and digital modules maintain consistent reference levels. Firmware flash compatibility is not applicable, but the supply aligns with standard DIN‑rail mounting practices across Series B and Series C chassis environments.

Frequently Asked Questions

Q: Can the 1606-XLP15E be hot‑swapped under load A: Power modules should be de‑energized before replacement. Live removal may interrupt downstream PLC and I/O circuits.

Q: Does the derating curve affect 24 V output stability A: Yes. Above +60 deg C, output power derates at 0.4 W/deg C. Loads should be sized accordingly.

Q: Is the module suitable for DC input operation A: Yes. It supports 88–375 VDC input ranges without configuration changes.

Field Installation Guidelines

• Maintain proper ventilation to dissipate 2.5–2.7 W internal losses.

• Route AC and DC wiring separately to reduce conducted noise into PLC analog modules.

• Avoid exceeding the 25.4 mm minimum cable bend radius near terminals.

• Ensure DIN‑rail seating is fully engaged to prevent vibration‑induced dropout.

• Verify output adjustment (24–28 V) before energizing downstream loads.
