Detailed Introduction to ABB Time Relay
Time relay is a very important component in electrical control systems, and in many control systems, it is necessary to use time relay to achieve delay control. Time relay is an automatic control device that uses electromagnetic or mechanical action principles to delay contact closure or disconnection. Its characteristic is that there is a delay between the signal received by the self attraction coil and the contact action. Time relays are generally used for controlling the starting process of electric motors as a function of time.
The main function of a time relay is as an executing device in simple program control. When it receives a start signal, it starts timing. After the timing is completed, its working contacts open or close, thereby driving subsequent circuit work. Generally speaking, the delay performance of a time relay can be adjusted within the design range, making it convenient to adjust its delay time. A single time relay alone may not be able to start delayed closing. After closing for a period of time, it can be opened again, achieving delayed closing and then delayed opening. However, overall, it can be achieved by configuring a certain number of time relays and intermediate relays.
With the development of electronic technology, electronic time relays have become mainstream products in time relays. Electronic intelligent digital display time relays using large-scale integrated circuit technology have multiple working modes, which can not only achieve long delay time, but also have high delay accuracy, small size, convenient adjustment, and long service life, making the control system simpler and more reliable.
