PRODUCT INFORMATION
Product Overview
Revision scope: These specifications describe 1756-A10/B (Series B). Check the corresponding technical data before specifying another hardware series.
The Allen-Bradley 1756-A10 ControlLogix Chassis provides ten module slots for industrial control systems. This chassis is designed exclusively for horizontal back-panel mounting inside an enclosure. The high-speed backplane delivers a communication path between installed modules. It also distributes operating direct-current power across all active slots.
Modules can be installed into any available slot within the assembly. The backplane provides multiple DC voltage rails for system hardware. Power rails supply 1.2V, 3.3V, 5.1V, and 24V DC backplane currents. Series B hardware features a North American T5 temperature code rating.
