2 Channel 12V Relay Module With Optocoupler Introducing the 12V 2-Channel Relay interface board – your solution for controlling multiple appliances and high-current equipment. With a built-in light coupling, this module meets safety standards by providing isolation between control and load areas through an isolation groove. The relays’ C, NC, and NO terminals are easily accessible via screw terminals, simplifying the wiring process. Plus, this board can be directly controlled by a variety of micro-controllers such as Raspberry Pi, Arduino, 8051, AVR, PIC, DSP, ARM, MSP430 or TTL logic.
