The Rish CON-I transducer series measures and convert ac current to dc process signals for direct input into monitoring systems such as recorders, data acquisition systems, panel monitoring instruments etc. The CON-I transducers process True RMS signals, providing accurate readings for signals that contain harmonic distortion. The input signal is converted into a load independent signal and the output signal generated is proportional to the mean root square value of the input current value.
