2 Channel Relays 3.3V/5V 10A 250VAC/60VDC Relay Module

Feature Can able to control various appliances and other equipment with a current not more 10A 250VAC 60VDC It can be controlled directly by microcontroller Raspberry Arduino AVR PIC DSP ARM or TTL logic For control of module need power 5V and logic operation 3 3V 5V To isolate the microcontroller from the relay we added optocoupler Now with this configuration the microcontroller doesnt have any physical connection with the relay it just uses the LED light of the Optocoupler IC to activate the relay This solution saves your microcontroller from a high voltage for VAC VDC Package includes 1 x Relay module
