Allen-Bradley 1769-L24ER-QBFC1B | CompactLogix 5370 L2 PLC Controller

Product Overview

The 1769-L24ER-QBFC1B from Allen-Bradley is a CompactLogix 5370 L2 packaged PLC controller. It delivers the same CPU performance as higher-tier controllers but offers a smaller, cost-effective form factor. This PLC is ideal for small applications such as hoisting, indexing tables, and packaging systems.

With 1MB of user memory, expandable via the included 1GB SD card or an optional 2GB SD card, the 1769-L24ER-QBFC1B can handle up to 32 tasks and 100 programs per task. Its modular design supports expansion of up to four additional 1769 modules.

The controller integrates a USB port, two EtherNet/IP ports supporting Device Level Ring (DLR), and facilitates up to 256 EtherNet/IP connections and 120 TCP connections, enabling efficient networked automation.

It features sixteen 24VDC sourcing digital outputs, sixteen 24VDC digital inputs, four high-speed counters, four universal analog inputs, and two analog outputs. This combination allows precise control and monitoring in a wide range of industrial scenarios.

The 1769-L24ER-QBFC1B operates on an embedded 24VDC power supply and supports an operating voltage range from 10 to 28.8VDC depending on ambient temperature, ensuring reliable performance in varying conditions. Continuous isolation voltage of 30VDC protects the module and connected devices.
