Allen-Bradley 1606-XLDNET4 AC Input Power Supply

The Allen-Bradley 1606-XLDNET4 is a DeviceNet power supply that converts AC input to a regulated 24 V DC output, delivering up to 91 watts of power and a continuous 3.8 A rating, with electronic current limiting to 4 A to protect downstream DeviceNet devices during overload or fault conditions and to help maintain stable voltage across the network. The unit accepts single-phase input in the 100–120 V or 200–240 V AC range, matching typical industrial mains, and is designed as part of Rockwell Automation’s 1606 family of switched-mode power supplies that are commonly used to feed 24 V DC I/O and devices on DeviceNet networks. It is classified as an NEC Class 2 power supply, which prescribes energy-limited output suitable for powering small networked devices, making it a safe, compact choice for DeviceNet sensor clusters and actuators in automation installations. Typical applications include powering DeviceNet-enabled sensors, actuators, and I/O blocks in factory automation where a compact, reliable 24 V DC source is required to maintain steady operation across distributed devices.
