Two channel 5V low level solid state relay module with fuse 2 Channel SSR Load 220V2A 


A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals. It serves the same function as an electromechanical relay, but has no moving parts and therefore results in a longer operational lifetime. SSRs consist of a sensor which responds to an appropriate input (control signal), a solid-state electronic switching device which switches power to the load circuitry, and a coupling mechanism to enable the control signal to activate this switch without mechanical parts. The relay may be designed to switch either AC or DC loads.


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


Use this module with arduino, nodemcu or any microcontroller to switch ON/OFF AC device like home use bulb, fan and etc.
