DZS-650 series intermediate relayDetailed product description：

Application of DZS-650 series intermediate relay
This relay is mainly used for relay protection of secondary circuits in power systems and DC circuits in industrial automation control, as an intermediate conversion and expansion control circuit.

2 Principles
This relay uses an RXMAl intermediate relay as its core, utilizing the charging and discharging characteristics of the RC circuit to achieve delayed action or delayed return. This series has three models: DZS-651, DZS-652, and DZS-653.

3 DZS-650 series intermediate relay technical data
