The Allen-Bradley 1775-A1 is a robust main processor chassis designed to house and protect a PLC-3 controller and its modules. Constructed from durable cast aluminum, it offers six module slots and utilizes a conventional cooling mechanism to ensure optimal air circulation, enabling reliable performance in diverse industrial environments. Its standout features include a power interlock bar to prevent module removal when powered, module covers for shielding against RFI, and status indicators for efficient troubleshooting. Additionally, the chassis supports field expandability for easy installation of expansion chassis or additional modules, while the front panel facilitates direct connections and provides critical status and diagnostic updates.
