Product Overview

The 5069-L320ERMS2 serves as a high-performance Compact GuardLogix 5380 controller, integrating standard and safety control into a single, compact unit. This SIL 2/PLd certified processor executes complex machine safety logic while managing high-speed motion and standard discrete I/O. We supply this unit as 100% Brand New original factory stock, ensuring the highest integrity for human-machine protection and system availability.

Technical Specifications

Engineering Advantages

• High-Speed Safety Logic Execution: The 5069-L320ERMS2 features a dual-core processing architecture. This dedicated safety core ensures that safety tasks execute with deterministic priority, reducing reaction times for E-stop and light curtain circuits without impacting standard machine throughput.

• Gigabit Communication Performance: Dual 1Gbps Ethernet ports support Star, Linear, and Device Level Ring (DLR) topologies. This high-bandwidth capability eliminates network bottlenecks when managing high-axis-count motion or dense remote I/O configurations.

• Unified Motion and Safety: The controller manages up to 8 CIP Safety drive axes over the network. This integration allows engineers to implement safe-torque-off (STO) and safe-speed functions over the Ethernet cable, significantly reducing hard-wiring labor and enclosure complexity.

• Modern Development Flexibility: The unit supports Ladder Diagram, Structured Text, Function Block, and Sequential Function Chart languages. This allows developers to choose the most efficient language for complex mathematical algorithms or standard sequence control within the Studio 5000 environment.

FAQs

What safety level does the 5069-L320ERMS2 achieve?

This controller meets SIL 2 (IEC 61508) and Performance Level d (PLd) requirements. It provides a cost-effective alternative to SIL 3 controllers for applications where a mid-level safety rating suffices for the risk assessment.

Can I use standard 5069 I/O modules with this safety controller?

Yes. The 5069-L320ERMS2 supports both standard 5069 Compact I/O and 5069 Compact 5000 Safety I/O modules. You can mix these modules in the same local rack to optimize your hardware footprint.

How does the dual-Ethernet port configuration work?

The controller allows you to configure the two ports with separate IP addresses (Dual-IP) for network isolation between the plant floor and the enterprise network, or as a single IP address for Device Level Ring (DLR) resiliency.

Is the memory expandable for large-scale projects?

While the 2MB user/1MB safety memory is fixed for logic execution, the controller includes a 2GB 1784-SD2 card. This card stores the project files, firmware, and user-defined data logs, providing non-volatile protection against power loss.
