Function
Remote substation communication hub
As a remote communication gateway between the local 800 series I/O rack (AS-H827 rack) and the central control 984 main CPU, all DI/AI/AO/DO signals are transmitted over long distances via coaxial cables.
data preprocessing
Local collection of I/O card signals such as AS-BDAO-216, AS-BDAI, AS-BANI, etc., packaged and uploaded to the main CPU; Simultaneously issuing CPU control instructions to drive on-site actuators.
Redundant fault-tolerant
Dual coaxial interfaces are used for dual line redundant wiring, which automatically switches to backup channels when a single cable is damaged, ensuring that power plants and chemical continuous processes do not trip.
Fault safety logic
When communication is interrupted, maintain output for a preset time to avoid instantaneous misoperation of valves and pumps.
