This single channel Relay Module operates at 5V TTL signal and is perfect for common Arduino/Raspberry Pi control applications. This board has one (1) on-board relay which can switch up to 10Amps. Relays terminals (C, NC, NO) are accessible through screw terminals which makes wiring up the board ver..
It is a 4 Channel Isolated 5V 10A Relay Module, A wide range of
microcontrollers such as Arduino, AVR, PIC, ARM and so on can control
it. It is also able to control various appliances and other types of
equipment with a large current.Relay output maximum
contact is AC250V 10A and DC30V ..
