Allen Bradley 1756-A13 ControlLogix 13-Slot I/O Chassis

Product Overview

The Allen Bradley 1756-A13 provides the structural and electrical backbone for large-scale ControlLogix automation systems. This 13-slot chassis houses processors, power supplies, and high-density I/O modules, enabling seamless high-speed data exchange across the backplane. It supports multi-processor configurations and distributed I/O architectures, serving as the central hub for mission-critical industrial control. We supply this unit as 100% Brand New original factory equipment, ensuring peak electrical conductivity and structural precision for your control cabinet.

Technical Specifications

Engineering Advantages

• High-Density Expansion: The 13-slot architecture maximizes I/O density within a single rack. This minimizes the need for additional expansion cables and remote I/O adapters, significantly reducing hardware costs and simplifying the overall system topology.

• Thermal Management Efficiency: The chassis design utilizes natural convection cooling to maintain stable operation up to 60 °C (140 °F). The open-frame construction facilitates consistent airflow around high-power modules, preventing localized heat pockets that could lead to premature component failure.

• Structural Rigidness: The precision-machined slot guides ensure perfect alignment between module pins and the backplane connectors. This rigidity prevents intermittent communication faults in high-vibration environments, such as those found in automotive assembly or mining operations.

• Cabinet Integration Optimization: The unit requires a minimum enclosure size of 60.9 x 76.2 x 20.3 cm. Adhering to these specifications ensures adequate clearance for wiring ducting and heat dissipation, solving common industrial pain points related to cramped cabinet space and cable stress.

FAQs

• Does the 1756-A13 include the power supply?

  No. The chassis provides the slots and backplane, but you must purchase a ControlLogix power supply (such as the 1756-PA72 or 1756-PB72) separately. The power supply mounts on the dedicated left-side position of the chassis.

• Can I use any slot for the ControlLogix processor?

  Yes. Unlike older PLC platforms, the 1756-A13 backplane allows you to place the processor in any available slot. This flexibility simplifies the organization of local and remote communication modules.

• Is this a refurbished or "new surplus" unit?

  Absolutely not. We guarantee this 1756-A13 is 100% Brand New, original Allen Bradley hardware. It arrives in its original factory-sealed packaging with full manufacturer traceability.

• What mounting precautions should I take?

  You must mount the chassis horizontally to ensure proper convection cooling. Vertical mounting restricts airflow and may void the temperature rating, potentially causing modules to overheat during high-load processing.
