4Ch Relay Module 12V
4-Channel 12V 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 purpose and many others. Input signals are given by microcontroller.
