ControlLogix Chassis Architecture
A four-slot chassis that distributes backplane power and communication between installed ControlLogix modules.
The Allen-Bradley 1756-A4 is a standard ControlLogix chassis with four module slots. Its backplane provides a high-speed communication path between installed modules and distributes power from the ControlLogix power supply. Rockwell Automation specifies horizontal mounting, a maximum chassis power dissipation of 4 W, an approximate weight of 0.75 kg and a minimum enclosure size of 50.8 x 50.8 x 20.3 cm. The chassis is an open-style component and its official lifecycle status is Active. Before ordering, verify the complete catalog number, chassis Series, power supply, module count, mounting orientation, cabinet clearances, grounding and environmental requirements.
