Product Overview
The Allen-Bradley 1762-OA8 is an 8-point solid-state output module from the MicroLogix series. It switches AC loads with triac outputs. Engineers use it in MicroLogix 1100, 1200, and 1400 systems. The module handles 85 to 265 Volts AC at 47 to 63 Hertz. It has 2 commons for flexible wiring. Each output drives up to 0.5 Amps. The minimum on-state current is 10 mA. The maximum voltage drop is 1.5 Volts at 0.5 Amps. The maximum bus current is 115 mA at 5 Volts DC. Heat dissipation reaches 2.9 Watts. The module measures 3.54 x 1.59 x 3.43 inches and weighs 0.5 pounds. It is a compact choice for panel builders who need reliable AC switching.

Installation Guide
- Mount the 1762-OA8 on a proper metal panel.
- Ground the module well before power-up.
- Remove all metal fragments before operation.
- Keep the finger-safe cover in place while wiring.
- Do not remove the cover unless final wiring is complete.
- Follow Allen-Bradley wiring and grounding guidelines.
- Check terminal torque and wire seating after installation.
Commissioning and Maintenance Convenience
Startup is fast. The 8 triac outputs and 2 commons simplify load grouping. The finger-safe cover protects technicians during wiring. The module needs no calibration. Keep the panel clean and dry. Check for loose wires at each service interval. The compact size saves panel space. The solid-state design has no moving contacts. This reduces wear in high-cycle switching tasks.
Compatibility Notes
The 1762-OA8 works with MicroLogix 1100, MicroLogix 1200, and MicroLogix 1400 systems. Confirm the controller supports the 1762 expansion bus. Check the 5 Volts DC bus current budget. The module draws up to 115 mA. Verify that the AC load stays within 0.5 Amps per output. Keep the 10 mA minimum load in mind for small loads.

Typical Applications
The 1762-OA8 suits AC control panels in packaging, material handling, and food processing. It drives contactors, solenoids, and indicators. It fits pump control, conveyor lines, and small machine cells. The 8-point layout helps when panel space is tight. The triac output handles frequent switching without contact wear.
Diagnostic Capability
Each output has a clear status indicator for fast troubleshooting. Technicians can confirm output state without a meter. The 2 commons allow separated load groups. This makes fault isolation easier. The 1.5 Volt maximum drop helps spot overload issues. Use the 10 mA minimum load rule to avoid false readings.
