Voltage inputs 0 – 10V
Description
Positive connection Input 1
Negative connection Input 1
Positive connection Input 2
Negative connection Input 2
10V is approx. 2 mA
Parameter Read
Value x
Value x
Read voltage at ADC input +A1,-A1
cat /sys/gpio_board_ADC/voltage/volt0/value
e.g. 6400
Parameter Read
Value x
Value x
Read voltage at ADC input +A1,-A1
cat /sys/gpio_board/ voltage_in1/value
e.g. 6400
Converting to volts
Voltage in Volt = value / 1000
Value = 6400 corresponds to 6.4V

Current inputs 0 - 20mA
