GIO100 – Cellular RTU

Cellular router with integrated RTU functionality.

The GIO100 is an industrial and rugged cellular router creating a secure and robust link to your remote devices using 2G/3G/4G communication. It features both router capabilities for IP-connectivity as well as RTU-functionality with integrated I/O which is accessed by the IEC60870-5-104, DNP3, SIA DC09, SNMP or Modbus TCP protocol. The integrated I/O capabilities could easily be expanded by connecting other RTU/IED that support Modbus RTU, Modbus TCP, IEC60870-5-101 or IEC60870-5-104 protocol.

Combine GIO100 with subscription AddSecure Link and you will get the secure cellular communication system “AddLink”.
