1756-A10 | Allen Bradley | ControlLogix 10-Slot I/O Chassis

Product Overview

The Allen Bradley 1756-A10 provides the physical and electrical backbone for any ControlLogix system. This 10-slot chassis facilitates high-speed data transfer between ControlLogix processors, I/O modules, and communication bridge cards via its high-performance backplane. It supports diverse system architectures, from standalone local controllers to distributed I/O nodes. We supply this unit as 100% Brand New original factory stock, ensuring the gold-plated backplane connectors and structural frame remain in pristine condition for mission-critical deployments.

Technical Specifications

Engineering Advantages

• High-Speed Backplane Throughput: The 1756-A10 utilizes a high-speed, multi-bus backplane that allows multiple processors to coexist and share data within the same rack. This architecture eliminates communication bottlenecks between high-speed motion modules and standard I/O.

• Superior Power Distribution: With a massive 15 Amp rating at 5.1 VDC, this chassis supports power-hungry modules, such as fiber-optic communication cards and high-density analog modules, without experiencing voltage drops that could lead to erratic system behavior.

• Passive Convection Cooling: The chassis frame design optimizes airflow around the modules. This convection-based cooling strategy removes the need for failure-prone external fans, increasing the overall Mean Time Between Failures (MTBF) for the entire control panel.

• Rugged Mechanical Alignment: The heavy-duty frame ensures precise module alignment. This rigidity prevents intermittent connection issues caused by thermal expansion or high-vibration industrial environments, protecting the expensive gold contact pins on the backplane.

FAQs

• Can I install any 1756 series module in any slot of the 1756-A10?

  Yes. The 1756-A10 offers universal slot compatibility. You may place processors, power supplies (in the dedicated left-side position), and I/O modules in any configuration that meets your specific system power and communication requirements.

• Does this chassis require a specific power supply?

  The 1756-A10 requires a 1756 series power supply (such as the 1756-PA72 or 1756-PB72). The power supply mounts directly to the left side of the chassis frame, converting plant AC or DC power into the regulated voltages needed for the backplane.

• How do I properly ground the chassis during installation?

  Always mount the chassis to a grounded backpanel. For optimal electromagnetic compatibility (EMC), ensure the mounting screws make direct metal-to-metal contact with the panel. This prevents ground loops and minimizes electrical noise interference in sensitive analog signals.

• Is this product factory sealed?

  Absolutely. This 1756-A10 is 100% Brand New and arrives in its original, unopened Allen Bradley packaging. We do not sell used, refurbished, or surplus items, guaranteeing you receive a product with zero operational history.
