Allen-Bradley 1769-OW8I CompactLogix 8 Pt D/O Relay Iso Module

Description 

The Allen-Bradley 1769-OW8I is a Compact I/O relay output module with eight individually isolated channels. Each channel provides Form A (normally open) relay contacts capable of switching both AC and DC loads. Designed for use with CompactLogix and MicroLogix 1500 controllers, it offers flexible voltage compatibility and reliable isolation, making it ideal for mixed-voltage control applications.

Information About 1769-OW8I

The 1769-OW8I belongs to the Compact I/O series and features eight isolated relay outputs, allowing each channel to operate at different voltage categories without grouping limitations. It supports operating ranges of 5–265 VAC and 5–125 VDC, making it suitable for switching solenoids, contactors, relays, and other actuators. The module delivers up to 2.5 A per point, with a maximum of 16 A per module, and introduces a typical switching delay of 10 ms for ON and OFF transitions. It draws 125 mA at 5.1 VDC and 100 mA at 24 VDC from the backplane, with total power dissipation of 2.83 W. The module is equipped with LED indicators for channel status and fault diagnostics, improving troubleshooting efficiency. Designed for DIN rail or panel mounting, it is compatible with Compact I/O power supplies (1769-PA2, -PA4, -PB2, -PB4) and supports up to eight modules before requiring an additional power supply. Accessories such as terminal block kits (1769-RTBN18) and replacement parts are available. With robust shock and vibration ratings, the 1769-OW8I is well-suited for industrial environments.
