As nice as they are for relay-based computers, there are times when you don’t want to deal with noise or the unreliability of moving parts. This is where solid-state relays (SSRs) are worth ...

Below you can see the basic block diagram of a common solid-state relay. Here, the incoming electrical control signal (input) is converted into an optical one inside the opto-triac. This optical ...

Solid State Relay (SSR) is a solid-state replacement of electro-mechanical ... SSR has been extensively used in a variety of application, such as industrial control, motor control, data acquisition, ...

Test precautions. Follow these precautions when testing solid-state relays, but don't be afraid to add your own: Always verify that the actual wiring matches the connection diagram. Be certain that ...

The proper selection of 3-phase solid state relays for motor control application depends not only upon a comprehensive understanding of 3-phase SSRs, but also of the 3-phase power system and ...
