USED Allen Bradley 1771-A3B PLC-5

The Allen-Bradley 1771-A3B is an I/O chassis, a crucial component in the Allen-Bradley PLC-5 programmable logic controller system. It functions by providing a housing for various 1771 I/O modules. These modules handle the input and output signals essential for controlling industrial automation processes.

This specific chassis, the 1771-A3B, boasts 12 individual slots for accommodating I/O modules. It's designed for 19-inch rack mounting or back-panel mounting, making it adaptable to different installation needs. The chassis itself is built for industrial environments, withstanding operating temperatures ranging from 32 to 140 degrees Fahrenheit and humidity levels between 5 and 95% (without condensation).

While the 1771-A3B is no longer actively produced by Rockwell Automation (formerly Allen-Bradley), it remains a valuable component for existing PLC-5 systems. It offers a reliable and flexible solution for expanding the I/O capabilities of these control systems.
