1756-A10K | Allen Bradley | ControlLogix 10-Slot Conformal Coated Chassis

Product Overview

The Allen Bradley 1756-A10K serves as the structural and communication backbone for high-performance ControlLogix systems. This 10-slot chassis provides the physical housing and electrical backplane connection for processors, I/O modules, and communication adapters. Unlike standard models, the "K" suffix designates a Conformal Coated version, specifically engineered to withstand corrosive atmospheres. We supply this unit as 100% Brand New and Factory Original, ensuring maximum operational integrity in critical infrastructure and heavy industrial applications.

Technical Specifications

The 1756-A10K delivers high-speed data synchronization across the backplane with the following physical and electrical parameters:

Engineering Advantages

• Extreme Environment Protection: The specialized conformal coating shields internal circuitry against humidity, salt spray, and corrosive chemical vapors. This protection prevents dendrite growth and PCB corrosion, effectively extending the hardware lifecycle in wastewater treatment, oil and gas, and chemical processing facilities.

• High-Bandwidth Backplane: The chassis utilizes a passive multilayer backplane that facilitates high-speed, deterministic communication between modules. It supports multiple controllers within the same rack, allowing for parallel processing and distributed control without communication bottlenecks.

• Flexible Module Placement: The 1756-A10K does not restrict module location. Engineers can place any module in any slot, including power supplies (which mount to the left side), simplifying hardware configuration and future expansion.

• Robust Electrical Distribution: The backplane distributes 5.1V, 24V, and 1.2V DC power with high amperage ratings (up to 10A on the 5.1V rail). This ensures stable voltage levels for high-density I/O modules and energy-intensive communication cards, even during peak processing loads.

• Rapid Heat Dissipation: The open-style design maximizes airflow across the modules. This layout dissipates the 5 Watts of internal heat efficiently, maintaining optimal operating temperatures within the control cabinet.

FAQs

• Is this 1756-A10K chassis 100% Brand New?

  Yes. We guarantee this unit is 100% Brand New and ships in its original factory-sealed Allen Bradley packaging. We do not provide refurbished or used surplus racks, ensuring you receive the full protective benefits of the conformal coating.

• Can I use standard (non-K) modules in this 1756-A10K chassis?

  Technically, standard modules will fit and function. However, to maintain the environmental rating of your system, we strongly recommend using Conformal Coated "K" version modules (e.g., 1756-L73K) with this chassis. Using standard modules creates a weak point in corrosive environments.

• What power supply is compatible with the 1756-A10K?

  This chassis accepts standard 1756 Power Supplies, such as the 1756-PA72 or the Conformal Coated 1756-PA72K. The power supply mounts directly to the left side of the chassis, occupying a dedicated space without consuming any of the 10 available module slots.

• Does the chassis require specific mounting hardware?

  The 1756-A10K mounts horizontally to a backpanel using four standard mounting screws. Always ensure a minimum clearance of 2 inches (50.8 mm) on all sides to facilitate proper airflow and module insertion/removal.
