WebFor a source logic, a PNP transistor provides a path to voltage for the electrical load. For a PNP transistor circuit to work, it must be connected to a NPN transistor circuit. In other words, a source logic circuit needs to be connected to a sink logic circuit. ... When dealing with wiring I/O between a PLC and a servo or stepper driver, a ... WebOct 1, 2015 · Connecting a NPN sensor to a PNP input. When the sensor connects to an NPN card so that there is no current conduction, the solution to this is to place a pull-up resistor, as shown in the following figure. It can be seen that when the sensor is activated its output transistor makes a short circuit at the input, the input current to the module ...
Control Basics: The Difference Between Sink and Source Logic
WebHere’s a simple way remember how to wire up a 3-wire DC PNP or NPN sensor: P NP = Switched P ositive. N PN = Switched N egative. “Switched” refers to which side of the controlled load (relay, small indicator, PLC input) is being switched electrically. Either the load is connected to Negative and the P ositive is switched ( P NP), or the ... WebJul 7, 2024 · The PNP sensor: To interface a PNP sensor with a Yocto-PWM-Rx, you need: To connect ground (-) of the external power supply and the sensor blue wire on the module ground. To connect the (+) of the external power supply and the sensor brown wire together. To connect the black wire on the channel of your choice. kscp working together
