CN4
AI2 analogue input channel can select voltage or current signal. When
pin 1 and pin 2 of the CN4 are short-circuited, AI2 channel inputs
voltage signal; when pin 2 and pin 3 of the CN4 are short-circuited, AI2
channel inputs current signal.
CN5
AO1 analogue output channel can select voltage or current signal.
When pin 1 and pin 2 of the CN5 are short-circuited, AO1 channel
outputs voltage signal; when pin 2 and pin 3 of the CN5 are
short-circuited, AO1 channel outputs current signal.
CN6
AO2 analogue output channel can select voltage or current signal.
When pin 1 and pin 2 of the CN6 are short-circuited, AO2 channel
outputs voltage signal; when pin 2 and pin 3 of the CN6 are
short-circuited, AO2 channel outputs current signal.
