Product Overview

The 1769-L24ER-QBFC1B is a high-performance, compact automation controller in the CompactLogix 5370 L2 series. This "packaged" controller integrates digital, analog, and high-speed counting capabilities into a single unit, making it ideal for small to medium-scale applications.

By embedding the I/O bank with the processor, it reduces hardware costs and simplifies installation. Dual Ethernet ports provide Device Level Ring (DLR) support, and a USB port enables easy configuration, offering a modern and scalable solution for industrial machine control.

Advanced Control Features

Studio 5000 Programming: Supports a unified engineering experience in the Logix Designer environment.
No Battery Required: Internal energy storage maintains volatile memory and the real-time clock during power cycles, eliminating the need for lithium battery replacement.
Integrated Motion: Supports up to 4 axes of EtherNet/IP motion (positioning only), ideal for small motion control systems.
Versatile Analog Inputs: Universal inputs accept a variety of voltage and current sensors without additional hardware.

Installation Guidelines

Designed for a single I/O bank; supports up to four additional 1769 modules.
Ensure sufficient clearance for airflow due to high-density 140 mm width.
Provide an external 24V DC supply capable of handling 21 W maximum power dissipation.

Common Technical Questions

What is the purpose of the dual Ethernet ports?
The dual ports allow the controller to function as an embedded switch, supporting linear and Device Level Ring (DLR) topologies. This provides network redundancy without an external managed switch.
Can I add more than one bank of I/O to this controller?
No. The 1769-L24ER-QBFC1B supports only a single I/O module bank. For multiple banks, consider an L3 series controller, such as the 1769-L30ER.
