2. Application mode of DI connected with PNP sensor
IN corresponds to IN on 2*5 3.5mm interface, and IGND corresponds to IGND on 2*5 3.5mm interface. The voltage
range of external power supply (DC) is 3V ~ 30V; the internal flow of the device is limited. In the normal voltage
range, the external power supply does not need to be limited.
Notes: The above example PNP Sensor is a DC three-wire NPN photoelectric switch or proximity switch.
3. Application mode of DO Driven NPN Triode
OUT corresponds to OUT on 2*5 3.5mm interface, and OGND corresponds to OGND on 2*5 3.5mm interface. The
maximum 2.5mA drive current can be supplied through OGND; the external power supply DC voltage range is
3V~30V.
Notes: The above illustration NPN is a common NPN triode.
