Allen-Bradley 1771-OAD
16-Point AC Output Module for PLC-5 Systems
Overview
The 1771-OAD is a 16-point AC output module designed for use in Allen-Bradley PLC-5 systems. It provides discrete control of AC-powered devices such as solenoids, pilot lights, and motor starters. Each output channel is individually fused and supports voltage ranges from 12 to 120 VAC. The module features zero-crossing switching to minimize electrical noise and includes fuse-blown detection capabilities for enhanced diagnostics.

Product Questions
-
Q: What types of loads can the 1771-OAD control?
A: It is suitable for controlling AC-powered devices such as solenoids, pilot lights, contactors, and motor starters. -
Q: How does fuse-blown detection work?
A: The module uses a jumper-selectable mode to report fuse status either via LED indicators or through the input image table of the controller. -
Q: Is the module compatible with all 1771 chassis?
A: No. It is not compatible with 1771-A1, 1771-A2, or 1771-A4 chassis.
