1606-XLE240EN Allen-Bradley Essential Power Supply, 24 V DC, 240 W
The 1606-XLE240EN belongs to the Allen-Bradley Bulletin 1606-XL Essential family. It delivers 24 V DC at 10 A from a 120 V-class single-phase feed. Output trims from 24 to 28 V DC. A DC OK relay contact gives a dry status signal to the PLC. An NTC limiter tames inrush current. Dynamic 120% power boost works below +45 °C. Screw terminals hold field wiring tight. The unit mounts on DIN rail or a flat wall. Rockwell still lists it as active as of October 2026.

Oiltech Controls Review
- The DC OK relay is the standout feature here. It saves a separate monitor relay.
- 91.3% efficiency keeps heat low inside a 60 mm wide body.
- 120% boost handles contactor pull-in without tripping the supply.
- Screw terminals suit field techs who prefer a torque wrench over push-in clamps.
- Active lifecycle status makes it a low-risk spare to hold.
Oiltech Controls Insight
- Set output to 24.5 V. It absorbs line drop on long DC runs.
- Boost drops above +45 °C. Check panel ambient before relying on it.
- Wire the DC OK contact to a PLC input. It flags supply faults early.
- Torque screw terminals to the value on the housing. Loose screws cause hot spots.
- Record the adjusted voltage and boost margin on the panel card.
Warranty and Dispatch
- 12-month warranty on all supplied units
- Dispatch within 24 to 28 hours after order confirmation
- Shipping by FedEx, UPS, and DHL
- Tracking number sent by email after dispatch
- Technical verification before shipment
FAQ
Q: What does the DC OK relay actually do?
A: It closes when output voltage sits in range. Wire it to a PLC input or a lamp. You get a hardwired supply fault signal without extra hardware.
Q: Can this unit run on 230 V AC?
A: No. This variant takes 90 to 132 V AC only. For 230 V feeds, choose a different 1606-XL variant. Wrong input voltage will damage the unit.
Q: How much load can the 120% boost carry?
A: It gives 12 A for short peaks under +45 °C. Use it for contactor or motor inrush. Do not run continuous loads above 10 A.
Q: Should I set the output to 24 V or 24.5 V?
A: Set 24.5 V for most panels. It covers voltage drop on long cable runs. Stay within the load device input range before you adjust.
Q: How do I pick between new and refurbished stock?
A: This model is still active, so new stock is easy to source. Refurbished units suit budget spares. Confirm test data, DC OK function, and the 12-month warranty before ordering.
