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

Product description - 8-channel relay module for ESP8266, ESP32, Arduino, Raspberry Pi

8-relay module is a versatile interface for controlling high-current devices using platforms such as Raspberry Pi, Arduino, Banana Pi, AVR, PIC, or ARM. Each of the 8 SONGLE relays operates at 5V DC and can handle current up to 10A at DC 30V or AC 250V. The relays are controlled by pulling the input to ground (0V). All relays have both normally open and normally closed contacts (NO, NC) and an LED indicating the relay state.

Thanks to optical isolation and a robust design, this module provides safe control of devices. Current consumption is 15-20mA, and the PCB dimensions are 138 mm x 44 mm. It is an excellent solution for microcontroller-based projects!
