Allen-Bradley 1756-A17 ControlLogix 17-Slot Chassis

The Allen-Bradley 1756-A17 17-Slot ControlLogix chassis provides a rugged, modular frame to house ControlLogix controllers, I/O modules, and communications cards within a single rack, with an integrated backplane for high-speed data transfer. Designed for panel or cabinet installation in industrial environments, it offers 17 module slots and an integrated power rail to feed mounted modules, supporting reliable backplane connectivity and scalable PLC infrastructure. Typical uses include manufacturing production lines, process control systems, material handling operations, water and wastewater facilities, HVAC control, and automated assembly cells where structured I/O integration improves system reliability and serviceability. It is compatible with ControlLogix processors, I/O modules, and communication devices, and common replacements for smaller configurations are 1756-A13 (13-slot), 1756-A10 (10-slot), and 1756-A7 (7-slot) chassis. Operating under industrial-rated temperature conditions, the 1756-A17 chassis serves as PLC system infrastructure for large automation deployments.
