A solid state relay is similar to a mechanical relay but used for Noiseless operations in Industries. It’s lifetime also higher as it doesn’t have any mechanical switching that can The mechanical relay uses electromagnetic principle and makes sound while latching. The Solid state relay is Silent and safe operations (in case of circuits near Inflammable gases).
This 5V 2 Channel Solid State Relay Module is capable of switching AC voltages between 100 and 240V at up to a 2A current. The module can be controlled from a 5V digital source such as an Arduino microcontroller, 8051, PIC, etc.
A resistive type fuse is provided on the module to help protect excessive current draw.
A Solid State Relay is similar to a mechanical relay where it can be controlled through a digital signal. Solid State Relay generates no noise and has a much longer lifespan in compared to the traditional mechanic relay.
