The SCHMIDT + HAENSCH Modbus RTU-4-20 mA converter enables the simple integration of digital process data into existing analog control systems. It reliably converts the Modbus RTU signals of the iCS2 process refractometer into a standardized 4-20 mA current signal – ideal for integration into PLC or process control systems. The compact design, simple configuration and stable signal transmission make the converter the ideal interface between modern sensor technology and classic control technology.
