Solid State Relay Circuit Diagram. Ssr or solid state relays are high power electrical switches that work without involving mechanical contacts instead they use solid state semiconductors like mosfets for switching an electrical load. The circuit can be easily drive ac load of 1000 watt.
Solid state relay circuit fig. It operates a similar way as a relay. Here only a simple block diagram is given to understand the working of ssr.
There are many benefits of using a solid state relay over a electromagnetic relay few main advantages are reliability fast switching speed output current can be controlled noise less drive from low current minimum 5ma or less drive from voltage as low as 3 6v dc.
This is the circuit diagram of solid state relay. Here you can see four blocks are there. There s no relay found just the electronics circuit which does the switching. The circuit can be easily drive ac load of 1000 watt.
