Relay is an electronic control device, it has a control system (also known as the input loop) and the controlled system (also known as the output loop), usually used in automatic control circuit, it is actually a small current to control the larger current of an "automatic switch". Therefore, it plays the role of automatic regulation, safety protection and conversion circuit in the circuit.

The role of each component in the circuit:

Transistor T1 is the control switch

Resistor R1 mainly acts as a current limiting function to reduce the power consumption of transistor T1

Resistor R2 gives transistor T1 a reliable cutoff

Diode D1 continues in reverse to provide a drain path in the relay coil for the triode to switch from on-off and clamp its voltage to +12V.

Selection of rated working voltage of relay

The rated operating voltage of relay is the most important technical parameter of relay. When using a relay, the working voltage of the circuit (that is, the circuit where the relay coil is located) should be considered first, and the rated working voltage of the relay should be equal to the working voltage of the circuit. Generally, the working voltage of the circuit is 0.86 of the rated working voltage of the relay. Note that the workpiece voltage of the circuit must not exceed the rated working voltage of the relay, otherwise the relay coil is easy to burn. In addition, some integrated circuits, such as the NE555 circuit can directly drive the relay to work, and some integrated circuits, such as the COMS circuit output current is small, need to add a transistor amplifier circuit to drive the relay, which should consider that the transistor output current should be greater than the rated working current of the relay.
