4-channel Relay Control Board Module With Optocoupler, 4 Way Relay Module For Arduino

It is 4 Channel Isolated 5V 10A Relay Module, A wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on can control it.

• It is also able to control various appliances and other types of equipment with large current.
• Relay output maximum contact is AC250V 10A and DC5V 10A. One can connect a microcontroller with standard interface directly to it.
• Red working status indicator lights are conducive to the safe use.
• It has a wide range of applications such as all MCU control, industrial sector, PLC control, smart home control.
•  This neat relay module features 4 x 5V relays rated at 10A/250V each. It is designed to switch up to 4 high current (10A) or high voltage (250V) loads with the help of microcontroller.
• Each relay can individually switch on/off by an opto-isolated digital input, which that can connect directly to a microcontroller output pin.
• It only requires a voltage of approx 1.0V to switch the inputs on but can handle input voltages up to 5V.
• This makes it ideal for 1.0V to 5V devices.
