WB I414N21 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.


The output signal (voltage or current) of this transducer is proportional to the rectified average value of input AC current or reflects the input current wave. They are suitable for general applications such as fixed frequency voltage supplies etc. 


This product adopts DIN Mounting Rail structure, convenient installation and disassembly. It is suitable for real-time measurement of power system, post and telecommunications system, railway monitoring system and so on.

Product Dimensional Drawing (unit: mm)


Iz output is based on the design of maximum 250Ω standard load resistors. When the load resistor RL is less than 100Ω, the reducing resistor Ro should be connected into the current-output loop circuit of the sensor, so that the sum of the load resistance is between 100Ω and 250Ω.
