DIGITAL INPUT: (X1 DIG IN)
Brief explanation for X1 DIG In:
The DIO0_GPI4 signal can be read via software. It is normally high. If 12-24V is applied between
pin X1 - In: 052 (+24 VDC) and pin X1 - In: 053 (GND), the DIO0_GPI4 signal will go to a low state.
The DIO0_GPI5 signal can be read via software. It is normally low.
If the pin X1 - In: 061 (+24 VDC) and pin X1 - In: 062 is shortened, the DIO0_GPI5 signal will go to a high state.
