Tolako 16 Channel Relay Module Board for Arduino with Optocoupler Protection Works with official Arduino Board

• Maximum load of normally-open port: AC 250V/10A;DC 30V/10A
• Trigger current: 3mA
• Working voltage: 12V
• With four fixing bolt holes for easy installation
• Works with official Arduino board

This relay module can be used in interactive projects. This module uses 5v high-quality relay. It can also be used to control lighting, electrical and other equipment. The modular design makes it easy to expand with the Arduino board (not included). The Relay output is by a light-emitting diode. It can be controlled through digital IO ports, such as solenoid valves, lamps, motors, and other high current or high voltage devices.
