Description

The Allen-Bradley 1756-A4 is a compact, high-performance chassis designed for use within the ControlLogix automation system. This 4-slot backplane provides the necessary electrical and mechanical infrastructure to house and power ControlLogix modules, including processors, I/O modules, and communication adapters. Engineered for industrial environments, it ensures reliable communication and power distribution across the backplane.

Features

• Supports up to four ControlLogix modules in a single chassis.
• Optimized for horizontal mounting configurations.
• Robust backplane design supporting 5V DC and 24V DC current requirements.
• Open-style enclosure suitable for standard industrial cabinets.
• Designed for seamless integration with the broader ControlLogix platform.

Installation Guidelines

• Ensure the chassis is mounted on a flat, stable surface within a suitable industrial enclosure to protect against environmental contaminants.
• Maintain adequate clearance around the chassis for ventilation to prevent heat buildup, respecting the 4 Watt maximum power dissipation rating.
• Always power down the system before installing or removing any modules from the chassis slots to prevent electrical damage.
• Verify that all modules are properly seated and secured using the integrated module locking mechanisms.
• Ensure proper grounding of the chassis to the system common to minimize EMI and protect against electrical transients.

FAQ

Can the 1756-A4 be mounted vertically?
The 1756-A4 is primarily designed for horizontal mounting. Consult the official Allen-Bradley ControlLogix installation manuals for specific thermal derating requirements if considering alternative orientations.

Does this chassis include a power supply?
No, the 1756-A4 is a backplane chassis only. A compatible ControlLogix power supply must be installed separately to provide power to the backplane.
