  • Page 3 Electrical Diagram 24V and GND are the power interface, D1 is the power indicator. Aout is the analog output interface, VR2 is the signal trimmer potentiometer. VR1 is the magnification (the output of 0-5V and 0-10V can be adjusted freely through this potentiometer). The load resistance of the sensor composed of R7 and RP2 potentiometer is in parallel relationship (can be changed by user).
