The 1769-L23E-QBFC1B is a CompactLogix packaged controller that is manufactured by Allen-Bradley. This controller is ideally used for small applications, able to control industrial machines or processes. This module comes with embedded I/O channels such as Sixteen (16) 24 VDC discrete inputs; Sixteen (16) 24VDC Discrete outputs; Four (4) Analog inputs; Two (2) Analog inputs and Four (4) High-speed counters. The 1769-L23E-QBFC1B also supports I/O expansion wherein up to 1769 Compact I/O modules may be installed. To communicate with Human Machine Interfaces (HMI), Supervisory Control and Data Acquisition (SCADA), and other visualization systems, the 1769-L23E-QBFC1B is provided with a single Ethernet I/P interface and One (1) RS232 serial port. The ethernet port supports 10/10 Mbps data transmission speed and is designed for networked topology while the RS232 port supports DF1 and ASCII protocol, ideal for point-to-point communication at a maximum speed of 19200 Kbaud rates. This controller comes with 512KB user memory which is non-expandable. This controller utilizes battery-backed RAM. A 1769-BA battery unit is installed to retain the data within the user memory. Located on the right side of the controller, this battery can be replaced with the unit and must be executed only when the controller is under power. The controller’s IP address can be assigned using the BOOTP-DHCP tool and by downloading the initial configuration through the serial port. When utilizing the serial port, recommended cable for use is the 1756-CP3 communication cable. This controller supports panel mounting with the use of a standard DIN rail or by fastening the device with screws through the provided mounting tabs.

The Allen-Bradley 1769-L23E-QBFC1B Packaged Controller is a high-performance, rugged, stand-alone programmable logic controller or PLC that can be used in any type of industrial measurement, control, or monitoring application. It is designed with 16 digital inputs, 16 digital outputs, a 9-pin isolated RS-232 Serial port, 4 differential or single-ended analog inputs and 2 single-ended analog outputs, high-speed counters (similar to the Allen Bradley 1769-HSC module), and an Ethernet connection via an RJ45 socket. Up to 2 Expansion 1769 Series CompactLogix modules can be added to the 1769-L23E-QB1B Programmable Logic Controller. Several types of peripheral devices can be added to the Allen-Bradley 1769-L23E-QBFC1B Packaged Controller such as Allen-Bradley Point I/O modules, PowerFlex 40 Variable Frequency Drives, or PanelView Plus 600 Terminals. Using the built-in EtherNet/IP port of the Allen Bradley 1769-L23E-QBFC1B packaged controller makes it possible to leverage the power of the Ethernet/IP network for providing fast and reliable connectivity of the device with most of the current industrial control platforms. This is made possible by layering the Common Industrial Protocol (CIP) over the standard internet protocols, such as the TCP/IP and UDP. By using standard, unshielded, Category 5 RJ45 twisted-pair cable, it is possible to leverage an Ethernet high-speed platform for half/full-duplex 10 Mbps or 100 Mbps operation. The Allen-Bradley 1769-L23E-QBFC1B packaged controller brings any small machine or industrial process a wide range of control and monitoring functions that were formerly only available for the biggest systems.
