Arduino 4-channel 5V 10A relay module

The 4 relay module is a versatile interface for controlling high-current devices using the Arduino Raspberry Pi, Banana Pi, AVR, PIC, ARM and other platforms. Each of the 4 SONGLE relays operates at 5V DC and can handle up to 10A current at DC30V or AC250V. The relays are controlled by shorting the input to ground (0V). All relays have both normally open and normally closed contacts (NO, NC) and a light emitting diode to indicate relay status. Thanks to its optical isolation and sturdy design, this module ensures safe control of the equipment. Current consumption is 15-20mA.. It's great for projects using Arduino, Raspberry Pi and other controllers! Specification:
