Ethernet I/O


Ethernet I/O

  • The ETH IO – 2.0 unit enables the user to monitor the Analog and Digital inputs, control relay outputs. The status of the slave units are connected to it through MODBUS protocol.
  • A single box of ETH IO – 2.0 contains 8 Analog inputs, 8 Digital inputs, 8 potential free relay contacts, a query based response unit on the RS 232 bus, and a RS 485 port to connect to the slave units. Up to 6 slave units can be connected through the RS 485 interface.
  • Using the LAN (RJ45 Connection), all of the information of the inputs and the status of the different units which are connected to it , will be sent to the main server.
