Product Overview
1606-XLP50B is a compact 24 V DC power supply from the Allen-Bradley Bulletin 1606-XL series. It delivers 50 W with 2.1 A nominal output. The unit mounts on DIN rail and uses spring terminals for fast wiring. An adjustable output range of 24…28 V supports small voltage drop compensation. A DC OK relay contact gives a simple status signal for panel diagnostics.
This model has no communication port and no fieldbus protocol. It is a pure power conversion module. Designers choose it for compact cabinets, machine control panels, and legacy 24 V DC systems that need a stable, approved supply.

Installation Guide
- Mount on standard DIN rail inside an enclosure.
- Use spring terminals for input and output wiring.
- Keep clearance for heat dissipation at -10…+70 °C.
- Connect the DC OK relay contact to a panel status input if needed.
- Set output between 24 V and 28 V with the adjustment screw.
Commissioning and Maintenance
- Verify input voltage before power-up: AC 100…240 V or DC 110…300 V.
- Check output at 24 V DC and confirm load below 2.1 A.
- Use the DC OK contact for quick fault checks.
- No communication setup is required. This unit has no protocol.
- Inspect spring terminals and ventilation during routine maintenance.
Compatibility Notes
The 1606-XLP50B fits systems that use a 24 V DC bus and a 50 W load budget. It suits Bulletin 1606-XL replacements and compact panels. The DC OK relay works with standard dry-contact inputs. No fieldbus or software driver is needed.
