Product Details
Product Overview
The Allen-Bradley 1606-XLDNET4 functions as a dedicated switched-mode power supply designed specifically for DeviceNet network architectures. It delivers a stabilized 24V DC output at 4 Amps (91 Watts), ensuring consistent voltage for network nodes and communication lines. Although the manufacturer officially discontinued this model in late 2017, we provide this unit as 100% Brand New original stock. This allows maintenance engineers to replace faulty components in existing legacy systems without the need for expensive rewiring or panel redesigns required by newer 1606-XLSDNET4 replacements.

Engineering Advantages
-
Flexible Input Options: The 1606-XLDNET4 supports both AC and DC input ranges. The manual switch allows seamless transitions between 120V and 230V AC, while the wide DC input range (210–375V) accommodates specialized industrial DC bus applications.
-
Network-Specific Regulation: Unlike generic power supplies, this module meets the specific voltage ripple and noise requirements of DeviceNet protocols. It prevents data packet corruption by maintaining a clean power signal across long trunk lines.
-
Simplified DIN-Rail Integration: The rugged mounting clip snaps securely onto standard 35mm DIN-rails. This vertical orientation optimizes airflow and minimizes the footprint within crowded electrical enclosures.
-
Direct Legacy Fit: As a "standard module," this unit maintains the exact physical dimensions of existing installations. This eliminates the mechanical interference issues often encountered when attempting to install modern, differently-sized replacement modules into tight spaces.
FAQs
-
Can the 1606-XLDNET4 handle 240V AC input?
Yes. You must set the input selector switch to the 230V position to safely handle 230/240V AC industrial power sources.
-
How does this differ from the newer 1606-XLSDNET4?
The 1606-XLSDNET4 is the manufacturer's suggested replacement. However, using our 100% Brand New 1606-XLDNET4 ensures a 1:1 hardware match, preserving the original system's engineering documentation and UL/CSA certification parameters.
-
Is the output voltage adjustable?
The unit provides a factory-set 24V DC output optimized for DeviceNet. While most 1606 modules offer minor trimming, users should maintain the 24V setting to remain within DeviceNet network specifications.
-
What mounting orientation provides the best cooling?
Mount the unit vertically on a DIN-rail with the input terminals at the bottom. Leave at least 40mm of clearance above and below the module to facilitate natural convection cooling.

Tech & Buying Guide
Understanding Marshalling Cabinets in Industrial Control Systems Architecture
Industrial control system deployments rely on structured signal distribution to bridge field instrumentation with central processing hardware. A marshalling cabinet serves as the vital intermediate connection point between heavy field home-run multi-pair cables and delicate input/output (I/O) modules housed inside Programmable Logic Controller (PLC) or Distributed Control System (DCS) enclosures. By segregating field cable terminations from control hardware, engineers maintain system flexibility, safeguard controller components, and streamline commissioning workflows.
FAT vs SAT in Industrial Control Systems: Key Differences and Execution Guide
Industrial control system deployment relies on strict verification protocols to guarantee operational safety, system stability, and regulatory compliance. Commissioning complex Programmable Logic Controller (PLC) racks, Distributed Control Systems (DCS), and Safety Instrumented Systems (SIS) requires two critical milestones: the Factory Acceptance Test (FAT) and the Site Acceptance Test (SAT). Both procedures validate that system automation meets design specifications, but they occur at different stages of project execution and target distinct operational risks.
Hub vs Switch vs Router in Industrial Automation Architecture
Modern factory automation relies on reliable industrial networking infrastructure to exchange real-time field data across operational technology systems. Engineers often encounter networking hardware like hubs, switches, and routers when integrating Programmable Logic Controllers, Distributed Control Systems, and SCADA monitoring nodes. Although these devices share physical ports, they operate at different layers of the Open Systems Interconnection reference model and deliver distinct traffic management capabilities.
