The 1769-L23E-QBFC1B is a CompactLogix packaged controller manufactured by Allen-Bradley. This controller is ideal for small applications controlling industrial machines or processes. This module features embedded I/O channels, including 16 discrete 24VDC inputs, 16 discrete 24VDC outputs, 4 analog inputs, 2 analog outputs, and 4 high-speed counters.
The 1769-L23E-QBFC1B also supports I/O expansion, allowing up to 1769 Compact I/O modules to be installed. For communication with Human Machine Interfaces (HMIs), Supervisory Control and Data Acquisition (SCADA) systems, and other visualization systems, the 1769-L23E-QBFC1B provides an Ethernet I/O interface and an RS232 serial port. The Ethernet port supports 10/10 Mbps data transfer rates and is designed for network topologies. The RS232 port supports DF1 and ASCII protocols, making it ideal for point-to-point communication with a maximum transmission rate of 19200 Kbaud.
The 1769-L23E-QBFC1B Allen Bradley CompactLogix Packaged Controller may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
RSLogix 5000 / Studio 5000: Programmable through Rockwell's Logix software ecosystem.
Firmware limitations: As it is a traditional L23 controller, its firmware support is limited to version 20. It cannot be updated to newer firmware versions such as V21+ or Studio 5000 Logix Designer.
If you need to replace faulty equipment or upgrade your machine, Moore Automated recommends the new 5370 L2 series. These modern direct replacements feature faster processing speeds, larger memory, dual-port Ethernet, and a battery-free design with built-in capacitors: 1769-L24ER-QBFC1B (Economy/Standard option) and 1769-L27ERM-QBFC1B (supports integrated motion axes via EtherNet/IP connection).
