Expert Review

This 1606-XLB240E is a workhorse. It does one job well: convert AC to stable 24V DC. The 95.2% efficiency keeps panels cooler. The DC OK relay is a rare find in basic supplies. It gives you early warning if output drifts. No communication port means no complexity. That is a plus for simple machines. The IP20 rating limits use to clean cabinets. Adjustable output helps with long cable runs. Derating above 60°C is standard. For system integrators, this unit saves wiring time. It snaps on DIN rail. Screw terminals accept solid and stranded wire. The Allen-Bradley brand ensures documentation and support. This is a smart pick for OEM panels and retrofits.

Manager’s Insight

Stock this model if you serve industrial automation clients. It fits PLC racks, sensor networks, and relay logic. The 240W rating covers many mid-size loads. No communication keeps cost low. But the DC OK contact adds value. Competitors often lack this. Lead time is short. Ship within 12 to 24 hours. Offer FedEx, UPS, DHL options. Customers get tracking fast. The 12-month warranty matches market standard. Use the UL/cUL/CE approvals as selling points. Target panel builders and maintenance teams. This unit replaces older 1606-XL models without rewiring. That is a strong upgrade path.

Ideal Equipment and Applications

• PLC control cabinets (Allen-Bradley CompactLogix, MicroLogix)
• Sensor and actuator loops (24V DC inductive and capacitive)
• Relay and timer circuits (industrial logic)
• Human-machine interfaces (HMIs) and panel PCs
• Building automation (HVAC, lighting control)
• Test benches and lab power distribution
• Retrofit projects replacing older linear supplies

FAQ

Q: Does this power supply have any network port?

A: No. It has no communication interface. No Ethernet, no serial, no fieldbus. It works as a standalone power source. You monitor it via the DC OK relay contact.

Q: Can I adjust the output above 24V?

A: Yes. The trim pot allows 24 to 28V DC adjustment. Turn clockwise to increase. Use a multimeter to set precisely.

Q: What is the derating rule?

A: Derate 6W per °C from +60 to +70°C. For example, at 65°C, max output drops to about 210W. Keep cabinet temperature below 60°C for full power.

Q: Is this unit UL listed?

A: It meets UL 60950-1 and cUL. It carries the CE mark. These are standard for Bulletin 1606 series.

Q: How fast do you ship?

A: We dispatch in 12 to 24 hours. We use FedEx, UPS, DHL. You get a tracking number by email.

Q: What is the warranty?

A: 12 months from delivery. Covers manufacturing defects. Does not cover misuse or incorrect wiring.

Q: Does it come with mounting screws?

A: No screws for the DIN rail. The unit has a built-in clip. You only need a standard 35mm rail. Screw terminals are on the front.

Q: Can I use this for battery charging?

A: No. It is a power supply, not a charger. It does not have charging logic. Use a dedicated charger for batteries.

Q: What if I need communication?

A: Choose a different model. The 1606-XL series has variants with IO-Link or Ethernet. This 1606-XLB240E is the basic version.

Q: How do I know the output is OK?

A: The DC OK relay closes when output is within range. Wire it to a lamp or PLC input. If the relay opens, output has failed.
