Symbol Definition of WB Series Electrical Isolation Sensor
The following is a definition of the symbols for the WB series of electrical isolation sensors/transmitters:
Vx: the measured voltage;
Ix: current to be measured;
Fx: the frequency to be measured;
VG: the waveform and effective value of the output voltage, tracking the change of the input signal and the output voltage, also known as the tracking type voltage output;
Vz: voltage absolute value conversion, indicating the DC voltage output scaled by the effective value;
V`z: voltage true RMS conversion, DC voltage output;
IG: the current waveform and the effective value of the output current source, tracking the change of the input signal, also known as the tracking current source output;
Iz: current absolute value conversion, indicating the DC circuit source output scaled by the effective value;
I`z: current true rms conversion, which is a DC current source output;
Fk: frequency absolute value conversion, which is an open circuit gate frequency scaled by a valid value;
F`k: frequency true rms conversion, which is the open gate frequency output;
GND: sensor output signal and auxiliary power supply common ground;
Tk: collector open gate output;
Rk: Relay contact output.
