Analogue inputs
2426
The analogue inputs can be configured via the application program. The measuring range can be set
as follows:
• current input 0...20 mA
• voltage input 0...10 V
• voltage input 0...32 V
The voltage measurement can also be carried out ratiometrically (0...1000 ‰, adjustable via function
blocks). This means potentiometers or joysticks can be evaluated without additional reference voltage.
A fluctuation of the supply voltage has no influence on this measured value.
As an alternative, an analogue channel can also be evaluated binarily.
In case of ratiometric measurement the connected sensors should be supplied with VBBs of the
device. So, faulty measurements caused by offset voltage are avoided.
