The CO2NTROL Sensor provides a Modbus RTU RS485 digital signal as standard. With the additional of the Wi 2G BlueTooth Wireless Adapter (Ref 243470) the sensor can provide two 4 to 20mA analog outputs in addition to the Modbus signal. Hamilton also offers signal converters for OPC, Profibus, and Profinet to ensure compatibility with various SCADA software and controllers.
