1606-XLP50EZ: Plug-Terminal 50 W Supply With Parallel Operation
The 1606-XLP50EZ is a compact switched-mode power supply in the Allen-Bradley Bulletin 1606-XL family. It delivers 24 V DC at 50 W and 2.1 A nominal. Plug/removable spring terminals speed up wiring and replacement. Parallel operation lets you share load or add redundancy across units. A DC OK relay contact reports output status to the panel. The unit has no communication port and no protocol. It suits machine panels, compact cabinets, and retrofit builds that need a fast-service 24 V supply.
Oiltech Controls Review
- Plug terminals cut swap time during service.
- Parallel operation supports load sharing and redundancy.
- 89.0% efficiency with 6.8 W typical loss.
- DC OK relay gives a hard-wired status signal.
- No power boost stage; plan loads around 2.1 A.
Where It Fits Best
- Panels that need quick terminal removal for service.
- Systems running two supplies in parallel for margin.
- Compact cabinets with a 50 W load budget.
- Retrofit builds using DIN rail and 24 V DC loads.
- Legacy control systems needing obsolete control system support.

Professional FAQ
Can I parallel two 1606-XLP50EZ units for more current?
Yes. The unit supports parallel operation. Set both outputs to the same voltage. Keep total load within combined rating.
Does this model offer a power boost for motor starts?
No. It has no power boost. Size loads around 2.1 A nominal.
Why pick plug terminals over fixed screw terminals?
Plug/removable spring terminals speed up wiring and unit replacement. They suit panels with frequent service.
How do I set up the DC OK contact?
Wire the DC OK relay contact to a dry-contact panel input. It reports output status without a communication port.
What should I check on a surplus unit first?
Verify output at 24 V DC. Confirm load below 2.1 A. Inspect plug terminals and the relay contact.
