Rail Data Diode HV Train

Data Diode for 110 VDC and 110 / 230 VAC operating voltage with train approvals

The RDD20 devices consist of 2 independent DATA IN and DATA OUT routers. Within the device there is a continuous unidirectional data connection (100 Mbit/s) from DATA IN to DATA OUT for the data transmission. Due to the security requirements, data transmission is only possible from DATA IN to DATA OUT. Data Diode for 110 VDC and 110 / 230 VAC operating voltage with train approvals
