What Are The Classifications Of Time Relays?

As one of the most common types of relays, time relays play a very important role in our work and life. The principle is to retain the input signal for a certain period of time - that is, the "delay effect", and then continue to execute the command of the input model, thereby completing the control of the line. Time relays can be found in everything from household appliances to high-tech technologies, such as spaceships.
Let’s briefly introduce the classification of time relays: if we only consider the principle of action. Time relays can be mainly divided into the following categories: transistor type, such as transistor relay; electronic type, such as AS18F PCB time relay; DC electromagnetic type, etc. Generally speaking, the air type is the most commonly used, and the electric type and transistor type have better performance, but the price is relatively high.
