What is a timer relay?

Time relay is a very important component in electrical control system. In many control systems, time relay needs to be used to realize delay control. Time relay is an automatic control electrical appliance that uses electromagnetic principle or mechanical action principle to delay the closing or breaking of contacts. Its characteristic is that there is a delay from the time when the self-attracting coil gets the signal to the action of the contact. Time relays are generally used for motor starting process control as a function of time.

The main function of the time relay is as an executive device in simple program control. When it receives the start signal, it starts timing. After the timing is over, its working contacts open or close, thereby promoting the subsequent circuit work. Generally speaking, the delay performance of the time relay can be adjusted within the design range, so as to facilitate the adjustment of its delay time. A time relay alone may not be able to start delay closing, and then disconnect after closing for a period of time, first realize delay closing and then delay opening.
