5.6 Digital input
Figure 12: Digital input: state vs voltage
The input range extends from 0 to 24VDC (30VDC max). A zero logic (OFF) state is detected when the input level is
below 5Vdc. A one logic (ON) state is detected when the input level is above 10Vdc.
Warning: the logic level is undefined when the input is ranging between 5 and 10VDC.
