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.

Model Number	Description
ETH IO – 2.0	Ethernet based Input Output Unit – RTU (Remote Terminal Unit)

The I/O Unit enables the monitoring and/or control of Analog, Digital Inputs & Outputs of devices through MODBUS RTU protocol.
A single box has 8 Analog, 8 Digital inputs and 4 potential free Relay contacts and requires only the setting up of Unit ID through a DIP Switch before use.
Using multiple units on the RS 485 Bus, up to 2000 Inputs and 1000 Output contacts can be easily realized.
Using our RS 485 to GPRS / WiFi / Ethernet Gateway products, monitoring and control of these units may be done over the wireless network / Internet etc.

I/O Unit	RS 485 MODBUS Input Output Unit

Addressable RS 485 to RS 232 Converter.
Users can easily add/remove a Serial Port in their RS485 network to talk to RS232 based Serial Devices with the added feature of addressability.
Power and Data Isolated RS485 port gives protection to the unit and also the connected RS232 device from the RS485 network.
Unit address can be set by 8 way DIP switch allowing 255 addresses.
Baud Rate and other RS232/RS485 port parameters are set by writing in to Modbus Registers.
Address 0 of the DIP switch loads known defaults to the RS232/RS485 ports ensure configurability at all times
Supports 2 Digital Inputs, 4 Analog Inputs & 2 Outputs.
