Digital display time relay

Digital display time relay uses an industrial single-chip microcomputer as the main core device. It is an important period to control the electrical system. It is generally divided into two types, one is an electrical appliance that can be powered on, and the other is an electrical appliance that can be powered off and delayed. The working principle of the digital display time relay includes electronic action and mechanical action. In the principle of electronic action, capacitors and electronic components are often used to achieve the effect of time delay. Mechanical action is the use of air bags and springs.
