Information About 1771-OAD
The 1771-OAD is a member of the Allen-Bradley 1771 I/O series and is built for compatibility with most 1771 chassis models that support AC output modules. It uses zero-crossing switching technology to minimize electrical stress on connected loads and extend component life. The module is well-suited for applications where AC output control is required, including solenoids, relays, and indicator devices. Its wiring arm, diagnostic indicators, and standardized rack-mount format make integration straightforward within PLC-5 systems.
Key Features:
- Sixteen AC Output Points: Provides individually controlled channels for managing multiple AC loads.
- Wide AC Voltage Range: Supports 10–138 VAC to accommodate varied industrial devices.
- Zero-Crossing Operation: Reduces electrical stress during turn-on, improving load longevity.
- Independent Status Indicators: Each channel includes an LED for simplified troubleshooting.
- Rack-Mount Architecture: Integrates directly into compatible 1771 I/O chassis.
- Wiring Arm Compatibility: Uses the 1771-WH wiring arm for convenient field wiring.
- Backplane Powered: Draws power directly from the PLC-5 chassis, avoiding external supply requirements.
- Programmable Output Capability: Supports diverse output types through configurable logic in the PLC-5 processor.
The 1771-OAD delivers the reliability and precision required for stable AC output control in industrial automation applications.
