Brand: ABB
Series: Advant S800 / 800xA — Redundant Field Communication Interface (FCI)
The ABB CI820V1, model 3BSE025255R1, serves as a redundant fieldbus communication interface within ABB’s S800 distributed I/O system. Designed for high availability, it ensures uninterrupted data exchange between field-level devices and control systems. Compact yet resilient, the module supports hot-swappable replacement and provides robust redundancy to minimize downtime in critical process environments.
