The SSJ series integrated circuit time relay (hereinafter referred to as the relay) is used in the secondary circuit relay protection and automatic control circuit of the power system as a delay device to enable the controlled components to obtain the required delay. This product is an integrated circuit and static relay with advantages such as high precision, low power consumption, intuitive and convenient setting, and wide range. The product is divided into three series: SSJ-10, SSJ-20, and SSJ-30, which replace electromagnetic relays such as DS-100, DS-20, and DS-30 with different structures.
