Switching between Current Sink (NPN) and Current Source (PNP)
11.2 Switching between CurrentSink(NPN) and
Current Source (PNP)
Before using, read “Before switching the current sink (NPN) / current source (PNP)” (p. 11)
carefully.
The NPN/PNP switch is used to change the type of programmable controller that can be supported.
