ALLEN BRADLEY 1769-L24ER-QB1B is a compact, high-performance, electronic test equipment used in industrial automation, data communication, and plant and process control. It is a Programmable Logic Controller (PLC) that is equipped with an embedded Ethernet port and 24 high-performance, individually-addressable I/O modules. The processor offers a memory capacity of up to 4K words, a single high-speed counter, and a communications port that connects to three devices simultaneously. It has four interrupt lines for special low latency control applications, and a variety of analog and digital I/O modules, which are all expandable. 1769-L24ER-QB1B is designed for harsh industrial environments, and it is robust enough to cope with temperatures ranging from 0° to 60°C. ALLEN BRADLEY 1769-L24ER-QB1B has an embedded Ethernet port, which supports a variety of communication protocols including Modbus/TCP, EtherNet/IP, and a variety of traditional serial communication protocols. The Ethernet port also supports cable lengths of up to 400 m (1,312 ft). It is also equipped with a high-performance DPI port (Digital Point Interface) for direct control over discrete components. 1769-L24ER-QB1B is equipped with internal non-volatile memory and a RESET input that keeps the logic unchanged even in case of power failure. For expanded I/O, the controller also features an RS-485 interface and 30 discrete inputs/outputs. There is also a built-in error block that automates the diagnosis and reporting of errors in the process, as well as an optional encryption module that can be plugged in the equipment for secure communication. ALLEN BRADLEY 1769-L24ER-QB1B has a built-in communications adapter that allows for remote access and programming of the system. It also has a watchdog timer that guards against unit lockups, and it provides self-checking to ensure proper behavior of the I/O modules. The controller is also capable of integrating all of the analog and digital inputs, the outputs and the communication into one comprehensive machine. 1769-L24ER-QB1B is an excellent choice for industrial automation applications and can be used with a range of PLC software packages and programming environments. Its extensive I/O capabilities and embedded Ethernet port make it ideally suited for data gathering and networked control applications, while its high-speed counter and optional encryption module make it a great choice for secure communications. Its robust construction and wide range of features make it a reliable and cost-effective choice for industrial automation and control applications.
