Relay Module 2-Channel relay, 5V low level trigger 10 A contacts U-Style Read/Write Speed:Class 102 Channel 5V Relay Module is a relay interface board, it can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, and so on. It uses a low level triggered control signal (3. 3 5VDC) to control the relay. Triggering the relay operates the normally open or normally closed contacts. It is frequently used in an automatic control circuit. To put it simply, it is an automatic switch to control a high current circuit
