Allen-Bradley 1606-XL240E Power Supplies
The Allen-Bradley 1606-XL240E, also cataloged as the 1606-XL240E Power Supply, operates as a dedicated hardware component for single-phase AC conversion and 24-28 VDC distribution within industrial automation enclosures. It directly provides regulated DC power to PLC processors, discrete I/O cards, and field instrumentation while delivering a 240 W rated output capacity across wide input voltage ranges.

Proportional Backplane Power and I/O Density Scaling
Designed to stabilize local DC bus delivery for high-density I/O chassis, the power supply isolates sensitive control electronics from primary mains voltage fluctuations. Consistent power regulation across the 100-240 VAC input spectrum maintains backplane bus communication velocity and supports stable execution during controller handoffs or firmware flash operations. Integrated overload protection mechanisms limit output current without causing total voltage dropouts during momentary inrush states.
Frequently Asked Questions
Q: Can the 1606-XL240E accept wide AC input variations during field operation?
A: Yes, the integrated front-end converter handles line input voltages ranging from 100 to 240 VAC continuous without manual tap selection or external transformers.
Q: How is the output voltage adjusted on the 1606-XL240E?
A: The front panel includes a potentiometer allowing fine-tuning of the output within a 24 to 28 VDC range to compensate for long field wiring voltage drops.
Field Installation Guidelines
- Mount the module vertically on an IEC standard 35 mm DIN rail inside an IP54 or higher industrial enclosure.
- Maintain at least 40 mm vertical spacing above and below the housing to facilitate unobstructed thermal convection cooling.
- Terminate AC line power (100-240 VAC) using copper conductors rated for local panel wiring temperatures and torque screw terminals properly.
- Ensure the primary earth ground wire connects to the module functional earth ground terminal to limit common-mode noise propagation.
- Verify output DC polarity and measure voltage across output terminals prior to powering connected PLC or field I/O devices.
