    A relay is an electrically operated switch, which has a control system (also known as the input circuit) and the controlled system (also known as the output circuit), usually used in automatic control circuit.It is actually "automatic switch" ,using a small electric current to control a larger current.Therefore, the relay has the effects on the automatical automatic adjustment, security, conversion circuit in the circuit and so on .
    Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal.
    The 16A relay module can be used in interactive projects. It can also be used to control the lighting, electrical and other equipments. It can be controlled through the digital IO port, such as solenoid valves, lamps, motors and other high current or high voltage devices.
    The main difference between 16A Relay module and the old version relay module is the Max switching current.The max switching current has been updated from 10A to 16A. 
    Warning: Please do not attemp to play with this module if you are not sure about it.  Over 36V may pose danger to your body.

    1. Review by Peter - Works well, but is the coil side opto isolated? Does it have a reverse biased diode to take care of coil back emf verified purchaser

      When the relay coil de-energises, a LCD display connected to the arduino displays random undecipheral characters. Thinking this might be due to a back emf problem as the relay coil field collapses, I found that resetting the LCD display 250 us after the relay was de-energised largely cured the problem.
