Allen-Bradley 1762-OA8 AC Digital Output Module – MicroLogix Expansion I/O Series
When a critical AC output channel fails on a MicroLogix controller, the consequences cascade instantly — conveyor lines halt, HVAC systems lose control, and production supervisors face unplanned downtime that costs thousands per hour. The Allen-Bradley 1762-OA8 is the precision-engineered solution that keeps those eight AC output circuits alive and reliable, delivering the switching capacity and electrical isolation that industrial environments demand. Without it, your MicroLogix system simply cannot drive the solenoids, contactors, and motor starters that modern automation depends on.
Within the MicroLogix 1762 expansion I/O family, the 1762-OA8 occupies a foundational role: it is the standard 8-point AC discrete output module designed for 120/240 VAC field devices. Globally, it is one of the most widely deployed output modules in the MicroLogix ecosystem, trusted by OEMs and system integrators across food & beverage, water treatment, HVAC, and light manufacturing. Its combination of compact DIN-rail form factor, broad voltage compatibility, and Rockwell Automation’s proven reliability makes it a benchmark product in the sub-compact PLC segment.

Key Features & Benefits
- 8 Independent AC Output Points — Drive solenoid valves, contactors, pilot lights, and motor starters directly from the module without additional relays.
- Wide Voltage Compatibility (74–265 VAC) — Operates seamlessly on both 120 VAC (North America) and 240 VAC (Europe/Asia) field wiring, reducing the need for separate module variants across global installations.
- Optical Isolation (1500 VAC) — Protects the PLC backplane and CPU from field-side voltage transients, ground loops, and electrical noise common in industrial environments.
- Dual Isolated Output Groups — Two groups of 4 points with separate commons allow mixed-voltage field devices on a single module, maximizing wiring flexibility.
- Compact DIN-Rail Form Factor — 40 mm wide profile integrates neatly into MicroLogix panel layouts without consuming excessive cabinet space.
- Plug-and-Play Expansion — Connects directly to MicroLogix 1100/1200/1500 via the right-side expansion port; no additional power supply required for the module itself.
- Rockwell Automation Ecosystem Compatibility — Fully supported in RSLogix 500 / Studio 5000 Logix Designer for seamless I/O configuration and diagnostics.
Industry & Equipment Applications
- Food & Beverage Processing — Controlling pneumatic solenoids on filling lines, conveyor diverters, and CIP valve manifolds.
- HVAC & Building Automation — Switching fan contactors, damper actuators, and pump starters in air handling units.
