Product Description

The Allen-Bradley 1771-OR module is a Relay Output Module designed for industrial automation systems, providing 16 isolated relay outputs capable of switching up to 240V AC or 125V DC. It integrates directly with the 1771 I/O chassis, supporting backplane communication through the PLC-5 or SLC 500 controller platforms. Compatible with standard 24V DC logic power, the module operates within a temperature range of 0°C to 60°C. Ideal for manufacturing, process control, and machinery applications, the 1771-OR excels in driving high-power loads like motors, valves, and solenoids. Its robust relay design ensures reliable switching and surge tolerance, though mechanical contacts may wear over time compared to solid-state alternatives. The module lacks integrated diagnostics but offers straightforward installation and compatibility with legacy Allen-Bradley systems.
