The Allen-Bradley 1769-L23E-QBFC1B is a versatile and feature-rich Programmable Automation Controller (PAC) from the CompactLogix 5370 L2 family. This packaged controller combines a 24V DC power supply, a 512KB memory, and a comprehensive mix of embedded I/O into a single, compact unit. Specifically, it includes discrete, analog, and high-speed counter channels. Furthermore, it features an Ethernet port and an RS232 serial port for flexible connectivity. Therefore, its design makes it an ideal solution for original equipment manufacturers (OEMs) and end users who need a compact controller for small machine control, packaging, and simple process automation applications.
The 1769-L23E-QBFC1B offers a comprehensive mix of I/O types. Specifically, it provides (16) 24V DC sinking discrete inputs and (16) 24V DC sourcing discrete outputs. Additionally, it features (4) analog input channels and (2) analog output channels for handling process signals. Moreover, it includes (4) high-speed counter channels for precise motion and position sensing applications. Meanwhile, its memory architecture includes 512KB of volatile user memory, which is maintained by a 1769-BA battery. This battery-backed RAM ensures data retention during power outages.
Connectivity is a key feature of this model. For instance, it features (1) Ethernet/IP port that supports 10/100 Mbps speeds for networked topologies. Additionally, it has a (1) RS232 serial port that supports DF1 and ASCII protocols for point-to-point communication. The serial port supports baud rates up to 38.4 Kbps. Besides these, the Ethernet port supports 8 TCP connections and 32 CIP connections, providing ample capacity for small-scale applications.
This CompactLogix controller is built to handle mixed I/O applications. First, it supports up to 32 tasks, with a maximum of 100 programs per task, giving you flexibility in organizing your control code. Next, programming is supported via standard IEC 61131-3 languages, including Relay Ladder, Structured Text, Function Block, and Sequential Function Chart. As a result, this versatility allows you to choose the best language for each part of your application, ensuring efficient code development.
The 1769-L23E-QBFC1B operates on a nominal 24V DC power supply. Specifically, its current draw is rated for its integrated components. For wiring, it accepts solid or stranded copper wire with appropriate insulation ratings. The controller also includes LED status indicators for each output channel, operating mode, and battery status, providing clear visual feedback.
Its compact design requires only 50mm (1.97 inches) of clearance for adequate airflow and natural ventilation. Furthermore, the unit supports DIN rail mounting or panel mounting using screws through the provided mounting tabs. This flexibility simplifies installation in various enclosure types.
Installing the 1769-L23E-QBFC1B is straightforward. For example, you can snap it directly onto a standard DIN rail or fasten it with screws. For reliable operation, ensure adequate clearance for ventilation. Moreover, you can expand the controller by adding up to (2) 1769 Compact I/O modules directly to its side. Meanwhile, you can integrate the system into a new or existing Ethernet network. Use the RS232 port with a 1756-CP3 cable for initial configuration, or assign the IP address using the BOOTP-DHCP tool.
