4 Channel Relay Module. Uses optocoupler driven relays to switch higher voltage and/or current applications with an Arduino, Raspberry Pi, Beaglebone, or other microcontroller or ARM boards.
Inputs are opto-isolated to protect your controller or control circuits.
Inputs are active low triggered -- to activate one of the relays requires t
