Product Description

The 1769-L24ER-QBFC1B (Part Number: 1769-L24ER-QBFC1B) is a highly integrated, "packaged" automation controller within the CompactLogix 5370 L2 family. This all-in-one processor is engineered for space-constrained applications, combining a high-speed logic engine with 16 integrated 24V DC digital inputs and 16 24V DC digital outputs. Additionally, this specific L2 configuration includes embedded high-speed counters and analog capabilities, making it an exceptionally versatile solution for machine-level control.

The controller features dual-port EtherNet/IP connectivity, supporting Device Level Ring (DLR) topologies to ensure network resiliency. Designed for the modern factory, it uses an SD card for non-volatile memory storage, eliminating the need for a battery. The 1769-L24ER-QBFC1B manages integrated motion on EtherNet/IP and supports local expansion via 1769 Compact I/O modules, providing a scalable bridge between standalone machine control and enterprise-wide integration.

Application Scenarios

The 1769-L24ER-QBFC1B is the preferred choice for small-to-mid-sized machinery requiring precise motion control and integrated analog feedback. Common applications include:

  • Automated packaging equipment

  • Sorting systems

  • Specialized assembly stations

Its compact form factor and powerful functionality make it ideal for environments where DIN-rail space is at a premium.

Frequently Asked Questions

Does this controller require a separate power supply module?

  • No, the 1769-L24ER-QBFC1B features an integrated 24V DC power supply that powers the controller and any locally attached expansion modules.

What is the advantage of the Dual-Port Ethernet?

  • The dual ports allow you to connect the controller in a ring (DLR) or linear daisy-chain configuration. In a DLR configuration, if one cable is damaged, the network automatically reroutes traffic, preventing a system shutdown.
