5v Relay Circuit Diagram. Circuit diagram of 5v relay posted by margaret byrd posted on january 2 2021. 5v dual channel relay module internal circuit diagram.
Moving on from components and pinout here is the circuit diagram of the dual channel relay module. A temperature controlled relay circuit. 5v and gnd and connect the control signal from arduino to control.
5v dual channel relay module internal circuit diagram.
One comes with a npn transistor and the other with a pnp transistor. Most relay modules whether 5v or 12v will come with the aforementioned connection and hence all you need is to give power supply to the relay module i e. There are two types of relay modules according to a type of control signal used for relay activation. The following picture shows the internal circuit diagram of the 5v dual channel relay module.
