Jumper 5V / 24V (digital inputs)
Each digital input has two pins, which can be connected to each other by a jumper.
The two left pins belong to DI0, the following belong to DI1 and so on.
If two pins of different channels are incorrectly connected, this does not lead to a
defect. However, signals from one input are transmitted to the other, which can lead
to unexpected behavior.
Check the correct jumper setting before a signal is connected to the inputs.
–
If no jumper is plugged in, the analog input is in the 24 V range (factory setting). If a
jumper is plugged in, the input is in the 5 V range. The switching levels of the inputs
are adapted according to this setting.
If you are still unsure which voltages are connected to the digital inputs, do not insert a
jumper and remain in the 24 V range.
