SHDSL/optical fibre/Ethernet product family

The HY104 family consists of various device variants to transmit mission-critical data in dedicated networks which require high levels of availability. Depending on the variant, the devices have WAN interfaces for transmitting via cooper wire and/or optical fibre.

As LAN interfaces, the boards have four Ethernet interfaces and provide one or two serial interfaces to transmit traditional data.

Its attributes make the HY104 family the ideal transmission system for telecontrol technology and process-data communication. Another special feature is that the HY104 family supports the IEC 61850, IEC 60870-5-101 and IEC 60870-5-104 protocols.


  • Communications in smart grids
  • Telecontrol systems that support the IEC 60870-5-104 and IEC 61850 protocols
