Description
+A1
Positive connection Input 1
-A1
Negative connection Input 1
+A2
Positive connection Input 2
-A2
Negative connection Input 2
The input current at
10V is approx. 2 mA
Note: The applied DC voltage must not exceed 10V.
Function:
Reading the voltage inputs (
v1.0.4 and older
)

Example:
Read voltage at ADC input +A1,-A1
Command:
cat /sys/senst2_ADC/voltage/volt0/value
Response:
e.g. 6400
Function:

Example:
Read voltage at ADC input +A1,-A1
Command:
cat /sys/senst2_board/voltage_in1/value
Response:
e.g. 6400
Note:
Conversion to volts
Formula:
Voltage in Volt = value / 1000
Example:
Value = 6400 corresponds to 6.4V
Current inputs 0 - 20mA
11.6.4
The analog current inputs of the MC100 SensT2 have two operating modes.
1. Supply of a current - current from the sensor - sensor with own power
supply
2. Low side shunt - with power supply for the sensor
