Description
This 4-channel relay interface board allows you to control different appliances and equipment that use high-current draws using low voltage outputs such as those used by microcontrollers like Arduino (ATmegas, ARMs) and ESP8266 development boards, or by SoCs like the ones on a Raspberry Pi or BeagleBone single-board computer.
These modules are very straight-forward to use, you connect the pin header to power (5V and Ground) and to the digital I/O of your microcontroller or SoC. Then, you use the screw terminals to connect the HOT/LIVE wires of your appliance and its supply. The supply wire goes into the COMMON terminal (located in the middle of each 3-pin terminal), and the HOT/LIVE wire goes into either the NO or the NC terminal located besides each the COMMON terminal. Depending on the logic level on the microcontroller/SoC side, the COMMON terminal is connected to either the NO or the NC terminal and can be switched back and forth by firmware/program s logic.
Please remember to always use proper precautions when working with high-current devices!
Features:
- 7.5×5.5cm breakout PCB for 4 independent, high-current relay modules!
- Sturdy (1.6mm), blue PCB with a 6-pin header on one side (Vdd, Vss, IN1~4) and 4×3-pin screw terminals on the other (NO, COMMON and NC)
