4-Channel 5V Relay Module With Opto Isolated Input is a 4-Channel Relay interface board with optocoupler that allows you to control various appliances, and other equipment’s with large current. It can be controlled directly by Micro-controller (Arduino, Raspberry Pi, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic). This board is used in home applications and industrial purposes and many others. Input signals are given by microcontrollers.
