Description
The Allen-Bradley 1794-PS13 is a robust, industrial-grade power supply module designed for the FLEX I/O distributed system. It converts standard AC line power into a regulated 24V DC output, providing essential power to FLEX I/O communication adapters and field-side circuitry. By delivering a stabilized power source, this module helps protect sensitive digital and analog signals from external power fluctuations within the I/O rack.
Features
- Wide AC input voltage range (85-264V AC) for global compatibility.
- Space-saving design for standard 35mm DIN rail mounting.
- Integrated over-voltage and over-current protection.
- Status diagnostic indicator for quick troubleshooting.
- Designed specifically for the FLEX I/O platform.
Applications
- Automotive assembly stations for pneumatic valves and sensors.
- Packaging and bottling lines requiring reliable power for conveyors and sorting gates.
- Material handling systems including palletizers and automated storage systems.
- Machine tool control, including coolant pumps and interlocks.
- Industrial HVAC control skids for dampers and fans.

Installation Guidelines
- Mounting: Hook the module onto a 35mm DIN rail and rotate it down until the locking tab snaps securely into place.
- AC Input Wiring: Connect 120/230V AC to the input terminals (A, B, C).
- DC Output Wiring: Connect the 24V DC output to the FLEX I/O adapter (Terminal G: +24V DC, Terminal H: 24V DC common).
- Daisy-Chaining: Use terminals D, E, and F to daisy-chain AC power to additional power supply modules if required.
- Ensure power is disconnected before installing or removing the module to prevent electrical shock or equipment damage.
