Allen-Bradley 1606-XLS480E Industrial Power Supply

Product Details

1606-XLS480E Product Description

The Allen-Bradley 1606-XLS480E is a 480W, 24VDC DIN-rail mounted power supply engineered for seamless contextual integration within Rockwell Automation's XLS Series control architecture. Designed to deliver stable, regulated DC power across multi-rack PLC deployments, this unit serves as the foundational power layer in distributed control systems where signal integrity, load redundancy, and long-term operational continuity are non-negotiable. Whether deployed in a ControlLogix, CompactLogix, or GuardLogix platform environment, the 1606-XLS480E ensures that every downstream module — from I/O cards to communication gateways — receives clean, consistent power within the defined voltage tolerance window.

At NANKMOS, every 1606-XLS480E unit undergoes pre-shipment functional testing and is backed by a 12-Month Warranty, ensuring that your control cabinet integration proceeds without unplanned downtime or component uncertainty. Our inventory is maintained for immediate dispatch, supporting both emergency replacement and planned system expansion scenarios across manufacturing, energy, and process industries.

The 1606-XLS480E is not a standalone component — it is a system-layer asset that anchors the power architecture of a complete Rockwell Automation control platform. In a typical ControlLogix 5580 deployment, the power supply feeds the 1756-A17 or 1756-A7 chassis backplane, ensuring that the 1756-L85E CPU module, 1756-EN2T EtherNet/IP communication module, and high-density 1756-IB32 digital input cards all operate within their rated voltage envelope. Any deviation in supply voltage at this layer propagates directly into I/O scan cycle instability and communication timeout faults — making the 1606-XLS480E's tight output regulation a critical system parameter, not merely a convenience.

In CompactLogix 5380 architectures, the 1606-XLS480E pairs with the 1769-L36ERM controller and 1769-IQ32 compact I/O modules to power field-side signal acquisition in space-constrained control panels. Its DIN-rail form factor allows co-mounting alongside 1492-J terminal blocks, 1492-CABLE wiring systems, and 700-HLT relay modules within a single enclosure, reducing panel footprint while maintaining full system modularity.

For redundant power architectures — common in GuardLogix safety-rated systems and SIL 2 process control applications — two 1606-XLS480E units can be configured in parallel using the 1606-XLSRED10 redundancy module. This configuration provides automatic load sharing and seamless failover, ensuring that a single power supply fault does not interrupt the 1756-L73S safety controller or the 1734-AENTR POINT I/O EtherNet/IP adapter serving remote I/O drops. The DC OK relay output on each 1606-XLS480E feeds directly into the 1756-IB16 digital input module for real-time power health monitoring within the Studio 5000 Logix Designer diagnostic environment.

At the communication layer, stable 24VDC power from the 1606-XLS480E sustains the 1783-BMS10CGP Stratix managed switch and 1756-EN2TR dual-port EtherNet/IP module, both of which are sensitive to voltage ripple that can cause packet loss or ring topology reconfiguration events. In PROFIBUS DP or DeviceNet architectures, the same power rail supports 1788-EN2DN EtherNet/IP-to-DeviceNet linking devices and 1203-USB drive communication modules, maintaining deterministic fieldbus timing across the entire control network.

Manufacturing & Discrete Automation: In automotive body-in-white welding lines and FMCG packaging systems, the 1606-XLS480E powers multi-axis servo drive enable circuits, safety relay modules, and vision system controllers within a single 24VDC distribution bus. Its high efficiency rating reduces heat dissipation inside sealed enclosures, extending the MTBF of adjacent components including 2198-H040-ERS3 Kinetix 5700 servo drives and 1734-OB8S POINT Guard I/O safety output modules.

Power Generation & Energy Utilities: In substation automation and turbine control panels, the 1606-XLS480E provides the stable DC backbone for 1715-AENTR redundant I/O adapters and 1756-RM2 ControlLogix redundancy modules. Its wide input voltage range (85–264VAC) accommodates the variable AC quality found in generator-backed UPS environments, while its ATEX Zone 2 certification permits installation in gas-risk classified areas adjacent to fuel handling systems.

Oil, Gas & Petrochemical: In SIL-rated emergency shutdown (ESD) panels and distributed control system (DCS) marshalling cabinets, the 1606-XLS480E supports the power requirements of 1715-OB8DE redundant digital output modules and Rosemount 3051 HART transmitter loop power circuits. Its parallel redundancy capability is essential for achieving the power layer availability targets required by IEC 61511 functional safety standards.

Water & Wastewater Treatment: SCADA-integrated pump station control panels rely on the 1606-XLS480E to power 1769-L19ER CompactLogix controllers, 1769-OF4 analog output modules driving variable frequency drives, and 1783-ETAP1F EtherNet/IP tap modules for network diagnostics — all within a single DIN-rail assembly that must operate continuously across wide ambient temperature ranges.

Mining & Metals Processing: In conveyor drive control systems and ore processing plant automation, the 1606-XLS480E's robust construction and high output current capacity support the simultaneous operation of multiple 1756-IF16 analog input modules monitoring load cells, belt scales, and temperature sensors, alongside 1756-OB16IS isolated digital output modules controlling high-current solenoid valves and motor starters.

Q1: Can the 1606-XLS480E be used in a redundant power configuration with ControlLogix systems, and what additional components are required? Yes. The 1606-XLS480E supports parallel redundancy when paired with the 1606-XLSRED10 redundancy module. In a ControlLogix 5580 redundancy system, two 1606-XLS480E units are connected via the redundancy module to provide automatic load sharing and failover. The DC OK relay output from each supply should be wired to a 1756-IB16 digital input module so that Studio 5000 Logix Designer can generate a controller fault or alarm upon power supply degradation. No additional firmware configuration is required beyond standard I/O mapping. NANKMOS maintains stock of both the 1606-XLS480E and the 1606-XLSRED10 for same-architecture procurement, and all units are covered under a 12-Month Warranty.

Q2: What is the compatibility scope of the 1606-XLS480E across Rockwell Automation PLC platforms, and are there any architectural constraints? The 1606-XLS480E is compatible with all 24VDC-powered Rockwell Automation platforms, including ControlLogix 5580/5570, CompactLogix 5380/5370, GuardLogix 5580, and Micro850 systems. It is not a chassis-mounted power supply — it is a DIN-rail unit that provides external 24VDC to I/O modules, communication adapters, HMI panels, and field devices rather than directly powering the ControlLogix chassis backplane (which uses the 1756-PB75 or 1756-PA75 chassis power supply). This distinction is critical during panel design: the 1606-XLS480E handles the field-side 24VDC bus, while chassis power supplies handle the backplane bus. Both layers must be sized and protected independently for a compliant, maintainable architecture.

Q3: How does NANKMOS ensure the 1606-XLS480E is ready for immediate installation, and what does the 12-Month Warranty cover? Every 1606-XLS480E unit shipped by NANKMOS undergoes pre-shipment functional testing, including output voltage verification, load regulation testing, and DC OK relay output confirmation. Units are inspected for physical integrity and packaged to prevent transit damage. The 12-Month Warranty covers manufacturing defects and functional failures under normal operating conditions from the date of shipment. NANKMOS maintains dedicated inventory of the 1606-XLS480E to support both planned system builds and emergency replacement scenarios, with fast dispatch available for urgent control system maintenance requirements.
