Allen-Bradley 1756-A10 ControlLogix PLC Chassis

The Allen-Bradley 1756-A10 ControlLogix PLC Chassis is a 10-slot backplane rack that serves as the foundation for ControlLogix I/O and compute modules. Designed for horizontal back-panel mounting in standard ControlLogix enclosures, the chassis accepts any 1756 module in any slot and uses 1756-N2 filler modules to occupy unused slots. The backplane provides high-speed intermodule communication and distributes power across slots, enabling a compact, scalable architecture for CPU, digital and analog I/O, and specialty modules within a single rack. As part of the ControlLogix family, the 1756-A10 supports expansion by adding modules to existing slots to meet evolving automation needs. Typical configurations place a CPU module in one slot and populate remaining slots with I/O, communications, and motion modules, delivering a flexible platform for industrial automation projects that require modular, centralized control and integrated I/O in a single chassis.
