1756-A13 13-Slot ControlLogix Chassis | Allen-Bradley

The Original New Allen-Bradley 1756-A13 13-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. The chassis is horizontally mounted only and requires a minimum cabinet size of 60.9 x 76.2 x 20.3 cm (24 x 30 x 8 in.) for installation.

Core Engineering Highlights:
13 universal slots | 15A @ 5.1V DC backplane current | High-speed multi-bus backplane | Horizontal panel mounting only | 5.4W power dissipation| 0°C to +60°C operating temperature| Open-style enclosure

Key Features:

• Original New Allen-Bradley 1756-A13 chassis

• 13 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

• Passive convection cooling — no external fans required under normal operating conditions

• Gold-plated backplane connectors for reliable signal integrity

• Horizontal panel mounting only (8 mounting tabs total: 4 top / 4 bottom)

• Compatible with standard and redundant power supplies (1756-PA72, -PB72, -PA75, -PB75)

• 0°C to +60°C operating temperature

• Open-style enclosure (IP20 equivalent)

• 1756-N2 slot filler modules recommended for unoccupied slots

• Suitable for use with Logix 5560, 5570, and 5580 product families
