Allen Bradley 1756-L85EP ControlLogix 5580 Process Controller

Product Overview

The Allen Bradley 1756-L85EP stands as the flagship high-performance processor within the ControlLogix 5580 family, specifically optimized for complex process control. This controller handles data-intensive applications by leveraging a massive 40 MB user memory and high-speed execution engines. The "P" designation identifies it as a specialized process controller, while the conformal coating ensures survivability in harsh, corrosive industrial atmospheres. We supply this unit as 100% Brand New original factory equipment to guarantee peak system performance and manufacturer-certified integrity.

Technical Specifications

Engineering Advantages

• Accelerated Data Throughput: The integrated 1 Gbps Ethernet port eliminates communication bottlenecks. It supports high-speed I/O cycles and motion control while simultaneously handling heavy HMI/SCADA traffic without compromising logic execution speed.

• Superior Harsh Environment Durability: The factory-applied conformal coating protects internal components from moisture, salt spray, and corrosive chemical vapors. This hardware-level shielding prevents trace oxidation, solving the common problem of controller failure in wastewater treatment or chemical processing plants.

• Simplified Large-Scale Integration: With support for up to 300 EtherNet/IP nodes, this controller manages massive distributed I/O architectures from a single point. This reduces the need for multiple processors, simplifying the network topology and lowering software licensing costs.

• Instant Diagnostics: The 4-character scrolling display provides real-time status codes and IP address information directly on the front panel. This feature allows technicians to identify network faults or hardware errors instantly without connecting a laptop, drastically reducing Mean Time To Repair (MTTR).

• Massive Memory Buffer: The 40 MB memory capacity accommodates extensive instruction sets, large tag databases, and complex function blocks required for advanced process PID loops and plant-wide sequence control.

FAQs

• What makes the "P" version different from a standard 1756-L85E?

  The 1756-L85EP includes specialized firmware features optimized for process control applications, such as enhanced instruction sets for the PlantPAx distributed control system (DCS). It also includes the conformal coating as a standard hardware feature.

• Does the 1756-L85EP require a battery for memory retention?

  No. The ControlLogix 5580 series utilizes energy storage technology that eliminates the need for lithium batteries. It maintains the user program and tag data in non-volatile memory during power cycles automatically.

• Can I use this controller in an existing 1756-A7 or 1756-A10 chassis?

  Yes. The 1756-L85EP installs into any standard ControlLogix 1756 chassis. However, for maximum performance and to utilize the full speed of the 5580 series, we recommend using Series B or Series C backplanes.

• Is this a factory-sealed unit?

  Yes. We guarantee this 1756-L85EP is 100% Brand New original stock. It arrives in the original manufacturer’s packaging with all factory seals intact, ensuring it has never been used, energized, or refurbished.
