Allen-Bradley 1606-XLSDNET4 DeviceNet Power Supply

Allen-Bradley 1606-XLSDNET4 DeviceNet Power Supply

The 1606-XLSDNET4 belongs to the Bulletin 1606-XL performance series. Rockwell Automation built this unit specifically for DeviceNet networks. It provides 24 V DC output at 91 W rated power. The output is current-limited to 4 A, which matches thin DeviceNet cable requirements. Engineers use it to power DeviceNet trunks and nodes in control cabinets. This supply meets NEC Class 2 rules for limited-energy circuits. Its narrow 40 mm housing saves DIN rail space.

Technical Specifications

Input voltage is AC 100 to 240 V nominal. DC input covers 110 to 300 V. Output voltage is fixed at 24 V nominal. The unit delivers 3.8 A nominal current. Output is current-limited to 4 A for thin DeviceNet cable protection. Rated power reaches 91 W. Efficiency is 92.0% typical, which keeps heat low. Ripple and noise stay at 50 mV maximum. These values ensure clean power for network devices.

Furthermore, a DC OK relay contact provides output status monitoring. Spring terminals allow fast wiring without special tools. The DeviceNet approval confirms compliance with ODVA power specifications. Additionally, the current limit protects thin cable from overload damage.

Mechanical and Environmental Parameters

The unit measures 124 mm in height, 40 mm in width, and 117 mm in depth. It weighs 620 g. The IP20 protection rating suits enclosed cabinet installation. Operating temperature spans -25 to +70 °C. Storage temperature ranges from -40 to +85 °C. Relative humidity stays between 5 and 95%, non-condensing. These ratings support reliable use in demanding plants.

Installation Guide

First, mount the 1606-XLSDNET4 on a standard 35 mm DIN rail. Next, connect the input wires to the spring terminals. Then wire the 24 V output to the DeviceNet power bus. After that, connect the DC OK relay for status monitoring. Finally, check output voltage and polarity with a multimeter before energizing the network. Keep clearance above and below the unit for airflow.

FAQ

Q1: What makes the 1606-XLSDNET4 suitable for DeviceNet?
A: It is DeviceNet-approved and current-limited to 4 A. This matches thin DeviceNet cable power requirements and ODVA specifications.

Q2: Does this unit meet NEC Class 2 requirements?
A: Yes. The 1606-XLSDNET4 is rated NEC Class 2. This limits energy output for safer wiring in industrial cabinets.

Q3: What output voltage and current does it provide?
A: Output is 24 V DC nominal. The unit delivers 3.8 A nominal current with a 4 A current limit.

Q4: What does the DC OK relay do?
A: The relay contact reports output status. It signals a controller when output voltage leaves the healthy range.

Q5: Which shipping methods do you offer?
A: We ship via Fedex, UPS, and DHL. Every order includes tracking and protective packaging.
