Input / Output Units

inputOur MODBUS enabled Input / Output Units provided complete flexibility for monitoring the Analog inputs, Digital inputs and to control relay outputs of various critical parameters. They support communication over RS485, Ethernet and over Wireless GSM network. Large number of such Inputs and outputs can be monitored by cascading these units in many combinations.

  • 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.

  • 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.
