Description
Positive connection Input 1
Negative connection Input 1
Positive connection Input 2
Negative connection Input 2
10V is approx. 2 mA

e.g. 6400
Conversion to volts
Voltage in Volt = value / 1000
Value = 6400 corresponds to 6.4V

Current inputs 0 - 20mA

1. Supply of a current - current from the sensor - sensor with own power
supply
2. Low side shunt - with power supply for the sensor
