EM-M25 is designed for measuring AC voltage. The device was designed for measuring mains voltage and as a converter to current signal. The AC voltage is measured as TrueRMS, in other words the device gives RMS output also from other than sin-based signals. The measured voltage is converted into 4...20mA signal. The devices primary and secondary is galvanically isolated. The device takes its supply power from current loop and requires no other power supply. The device can also be used as 1...5V signal transducer according to the schematic down low. EM-M25 is also efficiently protected from faulty connections and voltage peaks.
