Allen-Bradley 1794-PS13 | Flex I/O DC Power Supply Module

Product Overview

The Allen-Bradley 1794-PS13 is a Flex I/O DC power supply module designed for industrial automation systems. It provides a nominal 24V DC output at 1.3 A, sufficient to power up to four Flex I/O adapters. The input voltage range of 85–264 VAC, 47–63 Hz ensures compatibility with global industrial standards.

This power supply integrates with the Flex I/O system, supporting daisy-chaining of output power to multiple modules. It features overcurrent and overvoltage protection, shutting down automatically if output current exceeds 1.4 A or voltage exceeds 35V DC. A green status indicator confirms proper output voltage within the operating range.
