Humidity transducer WBI417S91

DIN railcurrent output

WBI417S91 converts AC input current into a load independent output signal RMS (0)4-20mA. It has adopted electromagnetic isolation principle for real time measurement of AC current from electric net or electric circuit. The product has certain advantages of total galvanic isolation between input/output, high accuracy, low drifting by temperature, and wide temperature bearable range, etc. Basic testing method for accuracy (1) According to the terminal definition table to connect the testing circuit; (2) The testing must to be done by under the following conditions； Auxiliary power: 24V±5％，ripple≤5mV Ambient temperature: 25℃±5℃ Relative humidity: RH(45～75)％ Accuracy for Signal Power Source instrument: 0.05
