Product Description

The 1769-L24ER-QB1B (Part Number: 1769-L24ER-QB1B) is a highly integrated, "packaged" programmable automation controller (PAC) within the CompactLogix 5370 L2 family. Designed for small to mid-size applications, this all-in-one processor combines control logic, a power supply, and a high density of onboard I/O into a single, compact footprint. It is an ideal solution for machine-level control where DIN rail space is limited but high performance is required.

This controller features 32 integrated 24V DC digital I/O points (16 inputs and 16 outputs) and dual EtherNet/IP ports. The dual-port design supports Device Level Ring (DLR) topologies, providing network resiliency by allowing the system to remain operational even if a single cable in the ring is disconnected. With a 0.75 MB user memory and a battery-less design that utilizes an SD card for non-volatile storage, the 1769-L24ER-QB1B is both reliable and easy to maintain.

Application Scenarios

The 1769-L24ER-QB1B is primarily used in high-speed packaging, material handling, and small-scale assembly machines. Its integrated I/O and dual Ethernet ports make it perfect for "smart" machines that need to communicate with other controllers or HMI systems while maintaining a small physical footprint.

Frequently Asked Questions
