Description Relay shield

The Relay Shield v1.1 is an advanced module, compatible with Arduino. It is designed for easy control of high voltages. This clever device has four mechanical relays. Each relay can switch up to 35VDC and 70W. You can control it directly via Arduino/Crowduino with digital IOs. An external 9V DC is required for power supply. Compared to its predecessor, the Relay Shield v1.0, the v1.1 offers improvements. It has four selectors for manual control, instead of the push buttons of the v1.0. This makes the operation easier and more intuitive. Important: Make sure that the pins of the relay shield do not touch the USB connector of the Arduino UNO when connecting.
