Relay Module – 4-Channel 5V with optocoupler for Arduino PIC ARM DSP AVR

Overview:

This is a 5V 4-Channel Relay interface board, Be able to control various appliances, and other equipments with large current. It can be controlled directly by Micro-controller (Arduino , 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).

If you have ever had a project that required an interface with a high power device that needed AC or DC voltage and high current levels you have probably already discovered that attempting to control those devices directly with your Arduino, Raspberry PI, or other Microcontroller/Microprocessor can be a real challenge. This board is designed to interface easily with your 5V IO's without consuming much current on your IO pins. 

Technical Specifications:
