Allen Bradley 1794-PS1 Flex I/O Power Supply Module

Product Introduction

The Allen-Bradley 1794-PS1 FLEX I/O Power Supply Module is a compact and reliable power supply module designed to provide consistent 24 VDC power to FLEX I/O modules in industrial automation systems. Part of the FLEX I/O series from Rockwell Automation, the 1794-PS1 ensures stable operation of connected I/O modules by converting standard AC input voltage into regulated DC output.

Supporting a wide AC input range of 120–230 VAC at 50/60 Hz, this module is suitable for global applications and provides up to 0.7 A or 0.4 A maximum output depending on input voltage. Its compact design, DIN rail mounting, and open-style housing make it easy to integrate within control panels, ensuring that the connected FLEX I/O modules receive reliable power for distributed control systems.
