1606-XLEDNET3 Allen-Bradley DeviceNet Power Supply 3.3A | Bulletin 1606-XL

1606-XLEDNET3 Allen-Bradley DeviceNet Power Supply | Bulletin 1606-XL | 24 V 3.3 A

The 1606-XLEDNET3 is a DeviceNet-dedicated supply in the Allen-Bradley Bulletin 1606-XL family. It puts 24 to 28 V DC onto a DeviceNet trunk at 3.3 A and 80 W. Input is manually selected between 100…120 V AC and 200…240 V AC. Efficiency runs at 90% typical, so cabinet heat stays low. Hold-up time reaches over 60 ms at 120 V AC. The 32 mm body leaves room for adjacent nodes on the rail. Use it where a DeviceNet segment needs its own clean power tap.

How It Sits on a DeviceNet Segment

• Feeds the trunk power pair at 24 V DC.
• No protocol stack inside, so no node address to set.
• Keeps supply current away from scanner and adapter loads.
• Manual input select suits both 120 V and 240 V plants.
• Open-frame DIN body lets air move across the board.

Lines and Equipment That Suit It

• DeviceNet trunk segments with many remote I/O nodes.
• Conveyor and palletizer networks running DeviceNet.
• Legacy automotive and food processing cells.
• Panels using 24 V valve islands and block I/O.
• Retrofit jobs that keep an existing DeviceNet cable.

Wiring and Commissioning

• Set the input select to match plant voltage before power-up.
• Land the trunk power pair on the DeviceNet tap terminals.
• Confirm 24 V DC on the trunk with a meter at both ends.
• Check total trunk current against the 3.3 A rating.
• Keep power wiring away from the signal pair in the duct.

Service and Checks

• Measure trunk voltage at the far node under load.
• Re-check input select after any plant voltage change.
• Clear dust from the open-frame board area.
• Confirm derating above +60 °C in hot cabinets.
• No firmware, no software, no node configuration.

Approvals

• UL 60950-1
• cUL
• CE marked

FAQ

Q: Is the 1606-XLEDNET3 a network module or a power supply?
A: It is a power supply. It feeds the DeviceNet trunk pair only. It has no protocol stack and no node address.

Q: How does input voltage selection work?
A: You set it manually to 100…120 V or 200…240 V. Set it before power-up. A wrong setting is the most common field fault we see.

Q: Can one unit power a long trunk?
A: It supplies 3.3 A at 24 V. Add trunk current across all nodes before you order. Long runs often need a second tap near the far end.

Q: Why does current drop from 3.3 A to 2.9 A?
A: The unit is rated 3.3 A at 24 V and 2.9 A at 28 V. Higher output voltage lowers current capacity. Size loads to the voltage you actually set.

Q: What should I check if the trunk shows low voltage?
A: Measure at both ends of the trunk under load. Then check the input select and the tap terminals. Also total the node current, since overload is the usual cause.
