ABUS bus is used for data transmission, which has long transmission distance, strong anti-interference ability and short circuit protection function. It can record 1000 historical gas alarm information, 1000 historical fault information, and 500 system operation information. With RS485 interface, it can communicate with the monitoring system in accordance with the communication protocol, and realize the remote display of alarm information. TF memory card reader (need to be customized), can easily realize the controller history data export and external configuration data import through TF memory card.
