A relay is an electrically operated device. It has a control system and (also called input circuit or input contactor) and controlled system (also called output circuit or output cont actor). It is frequently used in automatic control circuit. To put it simply, it is an automatic switch to controlling a high-current circuit with a low-current signal. This is 1 Channel 5V Relay Board Module For Arduino PIC AVR DSP ARM. A wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on can control it.

Technical Specification:

• Operating Voltage 5V
• Max Current : 20mA
  
• Relay Contact Current Capacity at AC250V: 10A
  
• Relay Contact Current Capacity at DC5V: 10A
• Size: 53mm*18mm*18.5mm (L*W*H)

 Features:

• The module meets the safety standards, and there are isolation grooves between the control area and the load area
• Module with optocoupler isolation can trigger more reliably and stably
• It has power supply and relay action instructions
• It can absorb and close brightly and disconnect lightly
• Relays can directly control all kinds of equipment and loads

Applications:

• Mains switching
• High current switching
• Isolated power delivery
• Home automation
