Information About 1769-L23E-QBFC1B
The 1769-L23E-QBFC1B belongs to the CompactLogix family and is engineered as a self-contained controller combining processor, power supply, and onboard I/O in a single compact assembly. It is equipped with sixteen 24 VDC digital inputs, sixteen 24 VDC digital outputs, four analog input channels, two analog output channels, and four high-speed counters, enabling broad application coverage from basic sequencing to advanced measurement tasks. Additional expansion is supported through up to two 1769 Compact I/O modules for further customization.
Its communication capabilities include an embedded EtherNet/IP interface, supporting 10/100 Mbps network performance for HMI, SCADA, and peer-to-peer communications. A built-in isolated RS-232 port allows DF1 and ASCII device connectivity, making it suitable for serial peripherals such as barcode scanners, sensors, message displays, and modems. The controller features 512 KB of user memory backed by a replaceable 1769-BA battery, ensuring program and data retention during power loss.
Designed for ease of integration, the 1769-L23E-QBFC1B supports DIN rail and panel mounting and offers IP address configuration via BOOTP/DHCP or serial download. Its compact footprint and multifunction I/O architecture make it ideal for standalone machines, packaging lines, process skids, and distributed control systems requiring reliable, high-performance control in a small form factor.
Key Features
- Integrated I/O Architecture: Includes 16 digital inputs, 16 digital outputs, 4 analog inputs, 2 analog outputs, and 4 high-speed counters.
- Dual Communication Interfaces: Built-in RS-232 port for DF1/ASCII and EtherNet/IP port for TCP/IP and CIP messaging.
- High-Speed Counting: Supports fast input processing for motion feedback or rate-based applications.
- EtherNet/IP Ready: RJ45 interface supports 10/100 Mbps network operation for controllers, drives, and visualization systems.
- Compact Packaged Design: Combines controller, power supply, and I/O into a single compact housing.
- Expandable System: Supports up to two additional 1769 Compact I/O modules.
- Battery-Backed RAM: Maintains data during power cycles using a replaceable 1769-BA memory battery.
- Industrial Installation Options: Supports both DIN rail and panel mounting for flexible control panel layouts.
The 1769-L23E-QBFC1B delivers the reliability and precision required for integrated control applications in CompactLogix-based automation systems.
