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

Product Overview

The 1794-PS13 is a power supply module from the Allen-Bradley Flex I/O system. It provides stable 24V DC power to Flex I/O adapters and modules. This unit accepts a wide input voltage range of 85-264VAC at 47-63 Hz. It delivers up to 1.3A output current and 31.2W power. The module features overvoltage and overcurrent protection. A green LED indicates output voltage between 20.4V and 28V DC.

Application Scenarios

This power supply is ideal for industrial automation systems using Flex I/O. It suits applications that require distributed I/O in harsh environments. The module powers four adapters and supports daisy chaining. Use it with AC and DC I/O modules. Typical industries include manufacturing, oil and gas, and water treatment.
