Siemens Solid State Relay Circuit Diagram. The relays are not suitable for the protection of single phase ac or dc loads. The input of solid state relay uses tiny control signal to drive large.
A mains 220 v solid state relay circuit with in built zero crossing detector is described in this article. The 3rb2 3rb3 solid state overload relays have been designed for the protection of three phase motors in sinusoidal 5060 hz voltage networks. 1 below shows the basic wiring diagram for testing a dc input solid state relay.
These delays must all be considered when determining the switching frequency.
