Description

The Allen-Bradley 1756-A10XT is a 10-slot backplane chassis engineered for the ControlLogix Extreme Environment (XT) series. This ruggedized hardware is specifically designed to maintain operational integrity in demanding industrial applications characterized by corrosive atmospheres, extreme temperature variations, and high levels of vibration. It serves as the foundational backplane for mounting ControlLogix processors, communication modules, and I/O modules in environments where standard-grade equipment may be susceptible to failure.

Features

• Extreme Environment Design: Built to withstand harsh conditions, including exposure to corrosive gases and rapid thermal cycling.
• High-Density Slot Configuration: Provides 10 slots for flexible system architecture and module expansion.
• Advanced ESD Protection: Rated for 6 kV contact discharge and 8 kV air discharge to prevent damage from static buildup.
• Hazardous Location Compatibility: Suitable for deployment in ATEX-certified Zone 2 hazardous areas.
• Environmental Resilience: Operates reliably in humidity levels ranging from 5% to 95% (non-condensing).

Technical Specifications

Installation Guidelines

• Mounting: Ensure the chassis is mounted horizontally on a flat, rigid surface to maintain structural alignment.
• Airflow: Maintain adequate clearance above and below the chassis to allow for effective convection cooling; do not obstruct the vertical airflow path.
• Grounding: Connect the chassis to a reliable, low-impedance earth ground to ensure proper shielding and ESD protection.
• Module Insertion: Always power down the system before inserting or removing modules to prevent electrical arcing or damage to the backplane pins.
• Environment: While designed for extreme environments, ensure the installation location remains within the specified temperature and humidity ranges to prolong service life.

FAQ

Is the 1756-A10XT compatible with standard ControlLogix modules?

Yes, the 1756-A10XT is compatible with standard Bulletin 1756 I/O modules, processors, and communication bridges, allowing for seamless integration into existing ControlLogix architectures.

What does the XT designation mean?

The XT designation indicates that the module is part of the Allen-Bradley Extreme Environment product line, which features enhanced protection against environmental stressors such as corrosive gases, high humidity, and extreme temperatures compared to standard-grade components.
