Product Overview

The 1769-L23E-QBFC1B is a comprehensive, all-in-one "packaged" automation controller within the CompactLogix 5323E family. Designed for space-constrained applications, this unit integrates the processor, power supply, and a high-density I/O bank into a single hardware footprint.

With 42 built-in channels—including digital, analog, and high-speed counting capabilities—it is ideal for small machine control and complex standalone applications requiring multi-signal synchronization. The "E" designation signifies integrated Ethernet communication for modern industrial networking, differentiating it from standard L23 models.

Diagnostics: LED indicators provide real-time CPU, I/O, network, and high-speed counter status.
Programming: Fully compatible with RSLogix 5000 / Studio 5000, supporting advanced Sequential Function Charts (SFC) for complex process logic.

Environmental and Physical Ratings

Thermal Management: Operates reliably between 0 °C and 60 °C.
Mechanical Resilience: Rated for 30 g operating shock and 2 g vibration resistance when properly mounted.
Mounting: Open-style enclosure compatible with 35mm DIN rail or direct panel mounting.
Response Times: High-speed processing with Off-to-On delay of 400 ms and On-to-Off delay of 200 ms for standard I/O points.

Common Technical Questions

What is the difference between the 1769-L23E-QBFC1B and the standard 1769-L23-QBFC1B?
The "E" indicates a built-in Ethernet/IP port. The non-"E" version relies solely on RS-232 serial communication. The L23E model is better suited for modern networked systems.
Does this controller require a separate power supply?
No. As a "packaged" controller, it includes an integrated power supply. Only an external 24V DC input is required.
