Allen-Bradley 1756-A10 ControlLogix Controller

Allen-Bradley 1756-A10 ControlLogix 10-Slot Chassis is a modular backplane enclosure engineered to house up to ten ControlLogix-compatible modules in a single, scalable automation rack. It provides a high-speed ControlBus backplane that interconnects processors, I/O, and communication modules, enabling flexible configurations within a unified ControlLogix system. Cataloged as 1756-A10, this chassis is designed for 19-inch rack mounting with an approximate footprint of 20 inches wide by 30 inches tall by 8 inches deep, making it a compact yet capable centerpiece for mid‑ to large‑scale installations. Note that the chassis itself does not include a processor or power supply; these components are installed separately to complete the ControlLogix system. Users typically populate the chassis with a combination of 1756-series processors, I/O adapters, and network interface modules to meet specific control, sensing, and communication needs, and link multiple chassis through compatible networking modules to build expansive control architectures. This 10-slot chassis is commonly employed in manufacturing automation, packaging lines, and process control environments where centralized control, easy expansion, and organized module placement are essential for reliable operation and straightforward maintenance.
