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.
