Key Product Specification

Allen-Bradley 1769-L24ER-QB1B combines a 1MB application memory controller with built-in digital I/O in a single unit, eliminating the need for separate base modules for basic applications and reducing overall cabinet space requirements.

It supports both Ether Net/IP and embedded Ethernet technologies, enabling easy connectivity to HMI, SCADA systems, other controllers, and cloud-based monitoring solutions.

This controller is fully compatible with Rockwell Software Studio 5000, the standard programming environment for Allen-Bradley Logix controllers, simplifying application development, debugging, and maintenance.

Core Features and Benefits

1. Dual Ethernet Connectivity

The Allen-Bradley 1769-L24ER-QB1B comes equipped with two independent 10/100Mbps EtherNet/IP ports, enabling users to separate plant-wide network traffic from machine-level control traffic.

This dual-port design improves network security, reduces congestion on critical control networks, and supports linear device-level ring (DLR) topologies for increased network resilience.

2. Integrated I/O

Unlike modular controllers that require separate I/O modules for basic input and output, the 1769-L24ER-QB1B integrates 16 24V DC digital inputs and 16 24V DC sinking digital outputs directly on the controller.

This integrated design significantly reduces the size of the control cabinet, cuts down on wiring time during installation, and lowers overall system cost for small applications that do not require a large number of I/O points.

For applications that need additional I/O, the controller supports expansion with up to 8 additional 1769 series I/O modules, including analog, digital, and specialty modules.

3. High Processing Performance

With 1MB of application memory and a high-performance 32-bit processor, it can handle complex control logic, motion control, and communications tasks simultaneously.

It supports ladder logic, function block diagram, structured text, and sequential function chart programming languages in Studio 5000.

The controller also supports tag-based programming.

4. Seamless Integration with Rockwell Ecosystem

As a native Logix 5000 controller, the 1769-L24ER-QB1B integrates seamlessly with other Allen-Bradley products, including Panel View HMIs, PowerFlex drives, Kinetix motion systems, and Factory Talk software.

It also supports CIP Security, protecting the controller from unauthorized access and cyber threats.

5. Easy Maintenance and Troubleshooting

By built-in status LEDs for power, network status, and I/O status, maintenance teams can quickly identify issues without connecting a programming device.

The USB port provides a direct connection for programming and troubleshooting, even when the network is down.

Removable terminal blocks make it easy and faster to replace the controller without rewiring all I/O connections.

FAQ

Q: Does the controller require a separate battery?

A: No. The 1769-L24ER-QB1B utilizes a built-in energy storage module instead of a traditional lithium battery; it is a maintenance-free design that eliminates the need for periodic battery replacement and the risk of battery leakage.

Q: Do the firmware version and software version need to match?

A: Yes. The controller firmware version must be compatible with the Studio 5000 Logix Designer software version.

For example, a controller using firmware version 31.011 requires at least Studio 5000 v32.

We recommend verifying the compatibility of your software version with the target firmware version before purchasing.

Q: Besides supplying hardware, do you provide technical support or product selection advice?

A: Yes. Floating Light Automation not only sells hardware but also offers professional advice on product selection, wiring guidance, and consultation on replacement solutions.
