Allen Bradley 1746-OW8 SLC 500 Relay Output Module

Product Introduction

The Allen-Bradley 1746-OW8 is a relay output module developed for the SLC 500 programmable controller platform. It is designed to provide flexible and electrically isolated switching for both AC and DC loads, making it suitable for a wide range of industrial control applications.

Equipped with 8 independent relay output points, the 1746-OW8 supports 5–125 VDC and 5–265 VAC at 50/60 Hz, allowing it to interface directly with diverse field devices without the need for additional interposing relays. The relay-based output design makes this module particularly well suited for mixed-voltage environments and applications requiring galvanic isolation between the controller and field loads.

The 1746-OW8 integrates seamlessly into SLC 500 I/O chassis and is commonly used in systems where reliability, versatility, and compatibility with various load types are critical.
