5.9
Analog 0..10V Interface
The 0..10V interface can be used for “simple” single
-ended voltage measurements, as well as demanding
“differential” measurements. The measuring is isolated
- thus it can be operated on a different ground
reference than the power supply.
5.9.1
Default 0..10V settings
To avoid sensor signal clipping, the voltage levels of analog channels must be kept within the range in
reference to the isolated GND :
•
negative Pin Voltage
≥
0V referenced to isolated GND
•
positive Pin Voltage
≤
15V referenced to isolated GND
The input resistance is 1MOhm.

Example: Wiring “single ended” measurement
As the data logger allows for advanced differential measurements, single ended measuring needs to
have all negative inputs wired to reference ground.
The signal side is isolated from the power side - thus signal ground can be different from supply ground.
5.9.3
Example: Wiring “differential” measurement
The data logger allows for true differential measurement. The following diagram illustrates the wiring.
