The measuring transducer RK170 is designed to convert current signals of measuring instrument outputs of A-ISOMETER®s (0…400 μA) and residual current monitors (RCM, RCMA) into standard current signals 0(4)…20 mA (0…10 V). These currents are usually required in process technology.

The analogue measuring instruments of the 9604/7204 series are designed for indication of measured values from Bender devices equipped with the appropriate current output.
