JOSEF STR-P-2/125V time relay for lighting electronic anti-interference

Description :

　　A time relay refers to a relay whose output circuit needs to undergo a specified and accurate time to produce a jumping change (or contact action) when an input action signal is added (or removed). It is an electrical component used in circuits with lower voltage or lower current to connect or disconnect circuits with higher voltage or higher current.

　　Time relay is a very important component in electrical control systems. In many control systems, time relay is needed to achieve delay control. It is an automatic control electrical device that uses electromagnetic principles or mechanical action principles to delay the closure or disconnection of contacts. Its characteristic is that there is a delay between the signal obtained from the self attracting coil and the contact action. Time relays are generally used for controlling the starting process of electric motors as a function of time, and their main function is to serve as an executing device in simple program control. When the time relay receives the start signal, it starts timing. After the timing is over, its working contacts open or close, thereby driving the subsequent circuit operation.

　　There are various classifications of time relays, such as DC electromagnetic time relays. It is widely used in electronic devices such as communication and automatic control, and is one of the most important control components. In addition, there are types of time relays such as air damping, electric, and electronic.

　　During the operation of a time relay, when the coil is energized, the armature and support plate are attracted by the iron core and instantaneously move downwards, causing the instantaneous action contact to connect or disconnect. After a certain period of time, the piston rod descends to a certain position, and the delayed contact is pushed by the lever to open the dynamic breaking contact and close the dynamic closing contact. The delay time of the relay is the period from the coil being energized to the completion of the action of the delay contact.

　　The delay performance of a time relay can be adjusted within the design range, making it convenient to adjust its delay time. This makes the application of time relays in production equipment very extensive, which can grasp the timing and improve the accuracy and performance of products. At the same time, time relays also have the function of automatic monitoring. By placing them together with other devices, they can form a program space route and achieve automated operation of the equipment.
