AB 1606-XLS240E-A Power Supply: 240W DIN-Rail Mounted Switching Power Supply

Technical Specifications

Main Features and Advantages

The Allen-Bradley 1606-XLS240E-A​ power supply module delivers a superior combination of robustness, flexibility, and intelligence. A standout feature is its exceptionally wide input voltage range (85-264 VAC), which allows it to operate reliably on any standard single-phase power worldwide without the need for manual taps or switches. This makes the 1606-XLS240E-A​ a truly global component, simplifying spare parts inventory for multinational operations. Its high efficiency, up to 95%, minimizes power losses as heat, which directly translates to lower operating costs, reduced cooling requirements in the panel, and increased long-term reliability. The power supply incorporates active Power Factor Correction (PFC), which reduces harmonic distortion on the input line, helping facilities meet power quality standards and lowering the stress on upstream transformers and wiring.Enhanced Diagnostics and Robust Design: The module provides clear operational feedback via two LED indicators—one for input power presence and one for output voltage status—enabling instant visual diagnostics at the device. It is built for challenging environments, with an operational temperature range starting at -25°C and including certifications for use in hazardous locations (ATEX/IECEx Zone 2). The output voltage is slightly adjustable (24-28 VDC), allowing fine-tuning to compensate for voltage drops in long wire runs. The Allen-Bradley 1606-XLS240E-A​ is engineered with a high inrush current withstand capability, protecting it from nuisance tripping during panel energization. Its comprehensive suite of protections (overload, short circuit, overvoltage, overtemperature) ensures a graceful response to fault conditions, often entering a constant-current mode or shutting down to protect both the supply and the load. The combination of these features—wide input range, high efficiency, built-in diagnostics, and industrial ruggedness—makes the 1606-XLS240E-A​ a dependable and cost-effective power cornerstone for any control system.

Application Field

The Allen-Bradley 1606-XLS240E-A​ 240W power supply is a versatile workhorse deployed across virtually every sector of industrial automation. Its most common application is as the primary DC power source within control panels for machine automation. In packaging, assembly, and material handling machinery, the 1606-XLS240E-A​ reliably powers the PLC (e.g., CompactLogix or Micro800 series), the 24VDC digital and analog I/O modules, photoelectric sensors, inductive proximity switches, and solenoid valves, ensuring the entire machine’s control logic and sensing infrastructure operates without interruption.In process industries and infrastructure, this power supply is integral to distributed control system (DCS) remote I/O panels, skid-mounted control packages, and motor control centers (MCCs). Here, it provides clean power for interface relays, chart recorders, loop-powered isolators, and local HMI terminals. The Allen-Bradley 1606-XLS240E-A​ is also extensively used in building automation systems for HVAC control panels, powering controllers, actuators, and damper motors. Its ATEX/IECEx Zone 2 certification makes it suitable for control panels located in potentially explosive atmospheres found in oil & gas downstream applications, chemical plants, and paint booths. Furthermore, in transportation and water/wastewater treatment, the module’s wide temperature range and robust design allow it to perform reliably in non-climate-controlled environments. Essentially, wherever a robust, efficient, and certified source of 24VDC power is needed to energize a cluster of automation devices, the 1606-XLS240E-A​ provides a trusted, off-the-shelf solution that integrates seamlessly with the broader Rockwell Automation ecosystem.
