This 5-Channel relay module is very well build. It uses optocouplers and even has cutted isolations of the board for security reasons. But beware that you need do remove the jumper and supply with 5V for the optocouplers to be usefull. If you dont care then you do not need any modification for it to work. The current for 1 Releay is about 80mA! Keep that in mind if you plan to supply it by an Arduino.
