Allen-Bradley 1756-A10 Programmable Logic Controller

The Allen-Bradley 1756-A10 is a 10-slot ControlLogix chassis that serves as the modular backbone for a ControlLogix rack, designed to host CPU, I/O, and communication modules and connect them over the high‑speed backplane. It uses a dedicated power slot on the left and provides ten module slots for standard 1756 modules, with horizontal mounting. Key specifications include a Series A design; dimensions listed as 20 x 30 x 8 inches; weight approximately 3.2 pounds (1.45 kilograms); maximum power dissipation of 5 watts; backplane current requirements of 10 A at 5 V DC and 2.8 A at 24 V DC. This chassis supports a broad range of compatible modules, enabling scalable automation configurations for factory floor control, process monitoring, and packaging lines where a single rack can house a CPU, digital and analog I/O, and communications modules to implement modular, maintainable control systems.
