● It can collect one circuit lightning current data, including lightning strike counting, magnitude detection, detection range 1-100KA, error ±10%. 
● It can collect 4 switch status, and emit alarm when closed. 
● The rated input voltage is 220V AC, the power consumption is small, and the power consumption of the whole cabinet is ≤5W. 
● LCD display is used to facilitate users to check the operating status, current alarms and historical records.
● Its built-in RTC real-time clock can accurately record the time of each event and alarm.
● The protected lightning protection device has more than 100 historical alarm records and more than 500 historical lightning event records.
● Follow RS485 half-duplex MODBUS RTU mode protocol communication; with simple networking, it’s convenient for centralized monitoring.  
● Lightning current detection can detect positive and negative polarities simultaneously. 
● The lightning protection data information in the smart surge protector can be collected through the bus and uploaded to the railway communication  transmission network through the Ethernet interface, or uploaded to the dynamic loop monitoring system through the RS485 interface, which is convenient for remote monitoring and can realize unattended.
