ABB 3BDH000690R1ABB CI920AS Communications Interface Module, Article No. 3BDH000690R1
ABB CI920AS Communications Interface Module, Article No. 3BDH000690R1 Core Function: The CI920AS is a fieldbus communication interface module designed for ABB Freelance DCS / Advant Controller 31 automation systems. It acts as a bridge between the controller CPU and external industrial fieldbus networks, enabling bidirectional data exchange between local I/O racks, remote field devices, operator stations, and upper-level supervisory systems. It supports standard industrial communication protocols, processes real-time process data, transmits alarm & diagnostic signals, and extends system networking capacity for distributed process control in chemical, pulp & paper, power, and manufacturing plants. It handles cyclic process value communication, event messaging, and bus fault diagnostics for
