Overview
The ABB CBI20 Binary Input Module is designed for precise and reliable digital signal acquisition in distributed control and safety systems. Featuring 32 input channels divided into two independent supply groups, it enables flexible wiring, fast event detection, and robust fault isolation. Part of ABB’s Melody series, it is widely deployed in power generation, chemical processing, and industrial automation.
The CBI20 offers 1 ms time resolution, making it ideal for time-critical applications. Its central galvanic separation between system inputs and internal electronics enhances signal integrity and safety. Therefore, it is suitable for environments where electrical noise, isolation, and uptime are critical.
For instance, in a turbine control system, the CBI20 can monitor limit switches and interlocks with millisecond precision, ensuring safe and responsive operation.
