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

Product Description

The 1769-L24ER-QB1B (1769-L24ER-QB1B) is a highly integrated, all-in-one automation controller from the Allen-Bradley CompactLogix 5370 L2 family. This processor is engineered for small to medium-scale machine control, offering a high-performance CPU combined with an embedded I/O bank of 32 digital points (16 DC inputs and 16 DC outputs). By consolidating the controller, power supply, and I/O into a single chassis, it significantly reduces panel space and simplifies multi-device wiring.

Equipped with dual EtherNet/IP ports, the 1769-L35E (1769-L24ER-QB1B) supports Device Level Ring (DLR) topologies for network resiliency and allows for daisy-chaining without external switches. A standout feature is its maintenance-free energy storage (capacitor), which eliminates the need for lithium batteries to preserve user memory during power loss.
