1769-L30ERMS | Allen-Bradley | CompactLogix GuardLogix Safety Controller CPU Module

Product Overview

The Allen-Bradley 1769-L30ERMS functions as a high-performance GuardLogix safety controller within the CompactLogix hardware platform. This specialized processing module coordinates standard automation tasks, safety-critical loops, and multi-axis synchronized motion profiles across a single integrated network architecture. We distribute this mission-critical automation core exclusively in 100% brand new, original factory-sealed condition to guarantee uncompromised internal energy storage cell life, verified MAC address configurations, and absolute safety execution integrity.

Technical Specifications

Engineering Advantages

• Combines Standard and Safety Control Code: The dual-core processing engine separates standard code execution (1 MB) from safety-critical execution loops (0.5 MB). This unified architecture achieves SIL 3 and PLe safety compliance, allowing engineers to govern functional safety shutdowns and standard sequencing within a single chassis, eliminating secondary interlock hardware.

• Synchronizes Multi-Axis CIP Motion over Ethernet: The module runs integrated motion control for up to 4 independent axes using standard EtherNet/IP (CIP Motion). This eliminates the cost and space consumption of specialized SERCOS network cards or pulse-train modules while minimizing drive command latency.

• Eliminates Internal Battery Maintenance: The integrated internal energy storage circuit generates the required holding current to write active cache parameters to the non-volatile SD card during a sudden panel blackout. This eliminates plant downtime associated with routine lithium battery replacements and prevents code loss.

• Enables Resilient Device Level Ring (DLR) Links: Dual onboard EtherNet/IP ports contain an embedded switch mechanism that supports ring network topologies. This architecture ensures the controller maintains steady data exchanges with remote I/O blocks even if a single branch of the field network cable tears or drops signal.

FAQs

• Does the 1769-L30ERMS safety controller require a separate safety partner module?

  No. Unlike older legacy GuardLogix processors that required a separate safety partner module in an adjacent slot, the 1769-L30ERMS incorporates the safety processing core directly into its compact 1.25 lbs single-slot hardware envelope.

• Is this GuardLogix processor an authentic factory-fresh unit or a refurbished piece?

  We guarantee this item is 100% brand new, authentic, and completely unused original factory stock. It arrives sealed inside its native manufacturer box with unblemished backplane connector traces, an unread 1784-SD1 card, and all original tracking serials and barcodes intact.

• Which power supply modules must I place next to this CPU?

  This controller connects directly with standard 1769 power blocks. Install a 1769-PA2 or 1769-PA4 for alternating current panels (120/240V AC), or use a 1769-PB2 or 1769-PB4 block for direct current environments (24V DC), ensuring the power supply mounts immediately to the left of the CPU module.
