Description
Allen-Bradley 1762-OA8 is a MicroLogix digital output expansion module designed to increase the output capabilities of compatible control systems. The module provides eight digital output channels and supports 120/240V AC output operation, making it suitable for switching and controlling field devices in industrial automation environments. With isolated I/O architecture and dedicated LED status indicators, operators can quickly monitor output conditions and system activity.

The module utilizes screw-type electrical connections to simplify installation and field wiring. Outputs are arranged into two isolated groups, with channels 0 through 3 assigned to Group 1 and channels 4 through 7 assigned to Group 2. This grouping structure enhances electrical separation between circuits and supports flexible application design. A maximum continuous current rating of 0.5 A per point, 2.0 A per common, and 4 A per module provides the capacity required for a wide variety of control tasks.

Electrical performance characteristics contribute to dependable operation in demanding environments. 1762-OA8 operates from an AC voltage range of 85 to 265V AC at 47 to 63 Hz and is classified within the 100 to 240V AC voltage category. The module features a maximum on-state voltage drop of 1.5 V at 0.5 A and an off-state leakage current of 2.5 mA at 265 V. Signal response is fast, with both on-delay and off-delay specified at 0.5 cycle for resistive loads.

Power consumption remains efficient, with a maximum bus current draw of 115 mA at 5V DC, equivalent to 0.575 W, while maximum heat dissipation is limited to 2.9 W. Surge current capability reaches 5.0 A with repeatability once every two seconds for a duration of 25 ms. These specifications allow Allen-Bradley 1762-OA8 to maintain stable operation during normal switching conditions and transient events.

Environmental durability makes 1762-OA8 suitable for industrial facilities. The module supports operating temperatures from -20°C to 65°C, while storage temperatures can reach as low as -40°C. It is rated for altitudes up to 2000 meters and operates within humidity levels ranging from 5% to 95% non-condensing. The module can be mounted on 35 × 7.5 mm or 35 × 15 mm DIN rails, and DIN rail end anchors are recommended for applications exposed to vibration or shock. As part of the MicroLogix expansion I/O family, Allen-Bradley 1762-OA8 provides a practical solution for manufacturing equipment, machinery control systems, and industrial process automation.
