ABB CBI20 High-Speed Binary Input Module for Automation and Monitoring

Description

TheABB CBI20 Binary Input Moduleis designed forprecise and reliable digital signal acquisitionin distributed control and safety systems. Featuring32 input channels divided into two independent supply groups, it enables flexible wiring, fast event detection, and robust fault isolation. Part of ABB’sMelody series, it is widely deployed inpower generation, chemical processing, and industrial automation. The CBI20 offers1 ms time resolution, making it ideal fortime-critical applications. Itscentral galvanic separationbetween system inputs and internal electronics enhancessignal integrity and safety. Therefore, it is suitable for environments whereelectrical noise, isolation, and uptimeare critical. For instance, in aturbine control system, the CBI20 can monitor limit switches and interlocks with millisecond precision, ensuring safe and responsive operation.
