Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1771-OAD is a 16-point digital AC output module in the Allen-Bradley 1771 (PLC-5) family. It provides field control by switching AC loads in industrial control systems. Typical applications include driving indicator lights, relays, solenoid valves, and motor starters. The module plugs into a 1771 I/O chassis (A1B-A4B, AM1, AM2) and interfaces with the PLC backplane. 1771-OAD offers channel-level status indicators and a fuse-blown indicator.
Best Suited For
- Switching multiple AC field loads (e.g., pumps, solenoids)
- Installation in PLC-5/1771 I/O chassis (A1B-A4B, AM1, AM2)
- Applications requiring zero-crossing switching technology
- Diagnostics via individual output and fuse status LEDs
