EM-M17b converts applied frequency to 0...10 V or to 4...20 mA signal. Frequency range is selectable with DIP-switches. Converter can be used with most of the commonly available transducer types. Frequency can be applied also as a pulsed voltage signal. The frequency input can be isolated optically if transducer supply and SW1/1 is left open. Converted signal is filtered using a 2nd order filter so that the ripple of the incoming frequency is efficiently attenuated. The output of EM-M17b is both short circuit and overload protected. Operating voltage range is wide and the supply is protected against incorrect polarity.
