Allen-Bradley 1606-XLS240E 1606-XLS Series Power Supply

The Allen-Bradley 1606-XLS240E, also cataloged as the 1606-XLS240E Switched-mode DIN-rail Power Supply, operates as a dedicated hardware component for AC to DC power conversion within 1606-XLS Series architectures.

Hardware Specifications

Industrial Control & Drive Integration

The 1606-XLS240E maintains electrical continuous voltage stabilization pathways to backplane bus communication velocity frameworks by delivering regulated 24 V DC power. Within complex architectures containing Profinet / EtherNet/IP deterministic networks, this hardware prevents voltage sag anomalies during peak step-loads. The integrated power reserve profile supports local I/O density scaling routines, managing high-current demands from physical field actuators without introducing noise or requiring specific firmware flash compatibility updates across the linked PLC rack components.

Frequently Asked Questions

Q: How does the 1606-XLS240E react during an output overload condition?

A: The power supply implements an automatic overload protection loop that limits current delivery to safeguard internal components. When the load drops back within the standard operating window, the hardware resumes standard 24 V DC output parameters without requiring an external system toggle or power cycling.

Q: Is specific firmware flash compatibility required to monitor this module?

A: No. The 1606-XLS240E operates strictly as an autonomous hardware component supplying physical electrical power. It lacks microprocessor-driven control interfaces on the internal backplane bus, eliminating any specific firmware or software dependency.

Field Installation Guidelines

• Mechanical Orientation and Airflow Clearance: Clip the component vertically onto a standard 35 mm DIN rail. To facilitate proper convection heat dissipation through the internal thermal chassis, leave a minimum clearance space of 40 mm above, 20 mm below, and 15 mm horizontally from adjacent devices.
• Electrical Conductor Connections: Wire the AC or DC input lines directly to the designated input terminals using rated copper conductors. Verify that the line protection devices match the specified 85-264 V AC or 90-150 V DC input parameters before energizing.
• Shield Grounding Infrastructure: Ensure the primary protective earth terminal is linked directly to a low-impedance functional earth ground bar. A solid grounding pathway is necessary to maintain internal surge voltage protection limits and prevent high-frequency noise injection into the 24 V DC output loop.
