Allen-Bradley 1756-L82EK ControlLogix 5580 Conformal Coated Controller

Product Overview

The Allen-Bradley 1756-L82EK stands as a high-performance cornerstone of the ControlLogix 5580 controller family. This Programmable Automation Controller (PAC) utilizes a high-speed multi-core processing engine to handle demanding industrial applications, including high-speed discrete control, motion, and process integration. The "K" suffix designates a conformal coated hardware build, specifically protecting internal circuitry against corrosive atmospheric contaminants. We provide this unit as 100% brand new and original, direct from factory-sealed stock.

Part Number Breakdown

The 1756-L82EK follows a specific functional logic:

• 1756: ControlLogix platform identifier.

• L8: Denotes the 5580 high-performance controller generation.

• 2: Indicates the 10 MB user memory capacity.

• E: Integrated EtherNet/IP port (1 Gbps capability).

• K: Conformal Coating for environmental protection.

Technical Specifications

This controller delivers massive I/O capacity and efficient power management:

Engineering Advantages

• Corrosion Resistance: The conformal coating shields the PCB and internal components from moisture, salt spray, and corrosive gases (ISA G3 environments). This ensures long-term survival in chemical plants, refineries, and wastewater facilities where standard electronics typically corrode.

• High-Bandwidth Connectivity: The onboard 1 Gbps Ethernet port facilitates rapid data exchange between controllers and HMI/SCADA systems. This high bandwidth supports the increasing data demands of IIoT (Industrial Internet of Things) without creating network bottlenecks.

• Simplified Architecture: The 5580 series architecture performs logic execution and communication tasks with significantly reduced scan times compared to the L7 series. This improved efficiency allows for more complex code within a smaller physical footprint.

• Enhanced Security: Built-in security features, such as digitally signed firmware and role-based access control, safeguard your industrial process from unauthorized modifications and cyber threats at the hardware level.

FAQs

• What is the advantage of the 1756-L82EK over the standard 1756-L82E?

  The "K" version includes a conformal coating. You should select this model for installations in harsh environments containing high humidity or corrosive chemicals to prevent premature hardware failure.

• Can I use this controller in an existing ControlLogix chassis?

  Yes. The 1756-L82EK installs into any standard 1756 ControlLogix chassis. However, it requires Studio 5000 Logix Designer version 28 or higher to access all advanced features and the 1 Gbps Ethernet port performance.

• Does the 1756-L82EK require a battery?

  No. Like other L8 series controllers, the 1756-L82EK utilizes an internal energy storage module to write the user program to non-volatile memory during a power loss. This eliminates the maintenance burden of replacing lithium batteries.

• How does the unit handle high-speed motion?

  The multi-core processor dedicates specific resources to motion tasks, supporting up to 256 axes of integrated motion over EtherNet/IP (depending on the specific application complexity).
