Allen-Bradley 1771-OD16

Interfaces your ON/OFF devices to AllenBradley programmable controllers within the 1771 Universal I/O structure. Allen-Bradley digital ac I/O modules interface to ON/OFF devices such as limit switches, pushbuttons, motor starters, pilot lights, and annunciators.

These modules are compatible with all current Allen-Bradley programmable controllers. This saves on spare parts, system engineering, inventory, and training costs. Supports high power operations. The ac solid-state family of digital I/O modules meets requirements for applications from 10-276V ac. These modules exhibit long life (20 million to over 100 million operations).

Provides system protection and troubleshooting aids. The ac I/O modules include electrical-optical isolation and filter circuits. To help you troubleshoot your system, module indicators are provided to show input or output status.
