EM-M22 TRMS 5A / 1A TO 4...20mA

67,00 € /unit

 EM-M22 is designed for measuring AC current. The device was designed to work with current transformer and as a converter to current signal. The AC current is measured as TrueRMS, in other words the device gives RMS output also from other than sinus shaped signals. The measured current is converted into 4...20mA signal. There are two measuring ranges, 5A and 1A, which are standard current transformer output values. The device takes it’s 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-M22 is efficiently protected from faulty connections and voltage peaks.
