Ssr Ac Schematic. A BTA40-600 and MOC3041 are used in this. A Process Controller has an AC output or a system generates an AC signal of above 100V AC to signal the load to turn on this.
In this project we will have a look at solid state relays find out how they work and when to use them and in the end create our own DIY Solid State Relay. Some designs with mosfets are also available. A BTA40-600 and MOC3041 are used in this.

The bridge rectifier formed by D1---D4 simultaneously converts the load AC input into rectified and filtered DC and this DC is used for biasing the gates of the MOSFETs. SSRs consist of an input logic to respond to an appropriate input control signal a solid-state electronic switching device to switch power to the load circuitry and a coupling mechanism to enable the control signal to activate this switch without mechanical parts. This is a AC Control Input AC Output SSR Solid State Relay. In this there is only semiconductor devices used no Mechanical coil relay is used to Switching the Connected Load.
