Inductive proximity switch three-wire NPN normally open how to control 24V relay

Answer:

Three-wire NPN proximity switch, if it is working power 24V DC. among them A line connected to the work of the positive power, usually brown, received 24V power positive There is a negative power supply is connected to the negative, generally blue, received 24V power supply negative

The remaining one is the output signal line, usually black. NPN output signal is low, that is, and the positive pole constitutes a loop. Your middle relay coil, a line connected to the power supply 24V +, from the switch out of the black signal line, connected to the relay the other end of the coil on it.

Upstairs is right, but you need to match a 24V power supply
