Encoder Input Expansion Module - EEN2
Using non-differential inputs:
„
When the non-differential inputs are used, the signal must enter at the non-negated input and
the negated input must be connected to the same GND as that of the module power supply.
In the figure below, there is an example where the module is powered with 5 V and the inputs
are using non-differential signals.
