Mechanical time relay principle

There are many different types of relays. Time relays are one of the more common types. They use time setting to control the electrical components of the circuit that turn on or off the voltage and current. When the relay working coil is driven to give a control current, the relay will pick up. Its contacts will be turned on or off. In control circuits, relays are often referred to as contactors.
Mechanical time relay

Time relays are widely used in electronic equipment such as remote control, communication, and automatic control, and are the most important control components. Commonly used time relays are mainly air damping type, electric type and electronic type. The time relay is also widely used in production equipment. It can accurately grasp the time measurement and improve the accuracy and performance of the product.
Time relay function
With the function of automatic time monitoring, multiple time relays can be connected to other control devices to form a program time control route to realize automatic operation of the control device. More and more smart products use time relays. The power-on delay type is characterized by its simple circuit and high reliability. When the attracting coil is energized, its momentary contact immediately acts. According to the established delay, the contact re-acts; after controlling the attracting coil to be powered off, touch The point is reset immediately.

The time relay with signal input has been widely used in automatic, remote control and monitoring. The trigger of the given signal, the relay on the automatic device together with other roads can form the program control circuit, which can be easily automated. run.
