1756-A10 10-Slot ControlLogix Chassis | Allen-Bradley

The Original New Allen-Bradley 1756-A10 10-Slot ControlLogix Chassis is the physical and electrical backbone for ControlLogix automation systems. It provides the backplane infrastructure for ControlLogix controllers, I/O modules, communication modules, and other 1756-series modules, enabling high-speed data exchange and scalable system expansion.

Core Engineering Highlights:
10 universal slots | 15 A @ 5.1V DC backplane current | High-speed multi-bus backplane | Horizontal panel mounting only | 5 W power dissipation | –25°C to +60°C (Series C) | Open-style enclosure

Key Features:

• Original New Allen-Bradley 1756-A10 chassis

• 10 universal slots — any 1756-series module can be installed in any slot

• High-speed, multi-bus backplane enables multiple processors to coexist and share data within the same rack
