Allen Bradley 1769-L24ER-QB1B CompactLogix 5370 L2 Ethernet Controller

Product Introduction

The Allen Bradley 1769-L24ER-QB1B CompactLogix 5370 L2 Ethernet Controller is a compact programmable automation controller designed for small to medium-sized machine control systems. As part of the CompactLogix 5370 L2 series, it integrates controller processing capability, digital I/O, and EtherNet/IP communication into a single compact unit, making it suitable for applications where space efficiency and reliable performance are required.

This controller includes built-in digital inputs and outputs, allowing direct connection to field devices such as sensors, switches, relays, and actuators. With integrated I/O, the controller simplifies system architecture and reduces the need for additional hardware modules in many automation environments.

The unit also features EtherNet/IP communication, supporting multiple network connections for communication with HMIs, drives, distributed I/O systems, and supervisory control platforms. Its communication capability enables efficient data exchange and supports modern network-based automation systems.

With 750 KB of memory, the controller provides sufficient capacity for machine control programs, data handling, and communication tasks. The device also supports expansion through additional 1769 I/O modules, offering flexibility for future system upgrades. The included 1 GB SD card allows convenient storage of programs, firmware updates, and backup data.
