4-channel 5V 10A relay module low-level triggered 0V Arduino

Product description

4-relay module is a versatile interface for controlling high-current devices using popular platforms such as Arduino, Raspberry Pi, Banana Pi, AVR, PIC, or ARM. Each of the 4 SONGLE relays operates at 5V DC supply voltage and can handle up to 10A at DC 30V or AC 250V. Relays are controlled by pulling the input to ground (0V - low state). All relays have both normally open and normally closed contacts (NO, NC) and an LED indicating the current operating state.

Thanks to optical isolation (optoisolation) and a robust design, the module provides fully safe control of external devices. Current draw is only 15-20mA. It is an excellent solution for microcontroller-based projects-ideal for Arduino, Raspberry Pi, ESP32, and ESP8266.
