The JS-11A series integrated circuit time relay adopts quartz crystal oscillator and large-scale CMOS integrated dedicated circuit, which has a much higher delay accuracy than electromagnetic time relay and RC time relay, providing a guarantee for shortening the time difference between main protection and backup protection in power system relay protection. It is an ideal product for replacing old-fashioned time relays. The appearance, internal wiring, and working mode of this series of relays are exactly the same as those of DS electromagnetic time relays, and the setting range is larger, the step difference is smaller, intuitive and convenient, starting from 0 Within the range of 02S to 999H, it can be adjusted arbitrarily to ensure accuracy without the need for verification. Mainly used in various protection and automatic circuits to provide adjustable delay for the action of controlled components.
