PiXtend eIO Hardware Manual
5.2.2.Jumpers for PiXtend eIO Analog One
Each PiXtend eIO Analog One device - regardless of which variant - comes with four
jumpers. These jumpers can be plugged in if required.
–
Jumpers 5 V / 10 V (analog voltage inputs)
Each analog voltage input has two pins that can be connected together by a jumper.
The two left pins belong to AI0, the two following to AI1 etc.
If no jumper is inserted, the analog voltage input is in the measuring range 0..10 V
(factory setting). If a jumper is plugged in, the range of the input changes to 0..5 V.
Reducing the voltage range can make sense if only small signals up to a maximum
of 5 V are to be measured. In this case, the full digital resolution is available for the
reduced measurement range.
If you are still unsure how high the voltage at the analog inputs can be, do not insert a
jumper and remain in the 0..10 V range.
