Wiring AI2
● AI2 is wired in the same way as AI1 when AI2 adopts voltage signal input.
● If AI2 is to be used for current signal input, the current flows from GND to AI2.
Toggle S2 (or S2 and S3) to ON. If only S2 is toggled to ON, the impedance is 500 Ω.
If both S2 and S3 are toggled to ON, the impedance is 250 Ω.
