Inputs and Outputs
Input channels
Analog inputs
The DDU 8 analog inputs accept an input signal of 0 to 5 V. A 3.01 kOhm pull‐up
resistor can be activated by software.
Digital inputs
The digital inputs of the DDU 8 accept 0 V to 5 V signals of Hall‐effect sensors by
default. Connect the output of the Hall‐effect sensor to the REVn_P pin and leave
the REVn_M pin open.
Page selection switch
Pin 36 of the DDU 8 life connector is used as a page selection switch for the dis‐
play. The internal pull‐up resistor is automatically activated. Display pages are se‐
lected by connecting the pin to SENSGND with different resistor values over a 12
position switch:
