I/O Types and Characteristics
Digital Inputs
DI’s can detect the presence of contact closures, transistor switches or on/off DC voltage
signals (low or high logic levels). Voltages below 0.8 VDC are interpreted as a low state.
Voltages between 4.0 VDC and 48 VDC are interpreted as a high state.
DI’s are also programmable to be NPN or PNP
