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.
