12V 4CH Relay Board

This is a 12V 4-Channel Relay interface board. It can be usedto control various appliances and other equipment with large current.The 4 channel relay boardcan be controlled directly by Micro-controller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic). This 12V relay switch is useful in creating a central hub from where multiple remote loads can be powered. It is useful for tasks like home automation where the module can be placed in the main switchboard and can be connected to loads in other parts of the house and can be controlled from a central location using a microcontroller.
