Though, for a core device like the PLC, they probably have the inputs configurable as NPN or PNP and the outputs as relay outputs rather than offer an NPN version. The sensor output is wired to the input point of the PLC. 3. When U3 is turned on it switching on a PNP transistor completing the current path though the H11AA1 to ground. Hence the simplistic information that just includes polarity, N/O, and output pin. #5. When selecting a sensor to be used with a PLC, it is very important that the sensor matches … With DC sensors, NPN and PNP may be terms you hear quite often. BUT. So NPN and. . Be on the look out when is 24V or 5V needed. A PNP input will switch the Positive or 24-VDC line.
The PLC designer can choose PNP or NPN to close the circuit and apply the voltage. The type of PNP or NPN must fit together in order to interface correct – for example if a input is a PNP input then the component (maybe a photo sensor) also must be a PNP type. NPN stands just for the type ("how the base would control the on-state", "how to connect Emitter and Collector in a schematics"). This allows that single PLC module to work with a few NPN sensors in a 24-volt system, right alongside a few NPN sensors in this 12-volt system. this is why it is better to use PNP/NPN terminology or double check datasheets. 전자과에서는 NPN, PNP 에 대해서는 소자 내부 특성에 대해서만 주구장창 배웠다.
If the transistor is connected between the device and ground, it is sinking current. PNP outputs. Cảnh báo!
