WBI414N21(4 to 20mA Output Current Transducer Low Power) adopts the special isolation module for real time measurement of AC current from power grid or circuit. It is converted to 0mA~20mA or 4mA~20mA DC current (Iz) output, and the characteristics of high precision, high isolation, wide frequency response, low drift, low power consumption, wide temperature range and strong anti-interference ability.
4 to 20mA Output Current Transducer Low Power is series of new device developed according to principle of electromagnetic induction. Its low current is stable. It is highly insulating between its primary coil and secondary coil. This sensor is used to measure current of signal system, circuit, and to measure current difference.
Applications:
AC power distribution system: such as power distribution cabinet, railway power supply;
Signal monitoring: such as AC current monitoring for filament relay, input signal monitoring for motor, etc.
