EM-M20 converts the position information of a potentiometer to milliampere signal ( 4...20 mA). Converter acquires its operating voltage from the current loop and needs no additional supply. Adjustments have no mutual effect. This makes the adjusting more easy and faster. The filtering can be selected from four alternatives to be suitable for different applications. Versatile protection circuits protect the converter from interfering peaks, over voltage and incorrect connections.
