Specifications and Features:-
 
 2 channel Relay Board
Relay Operating Voltage: 3.3V to 5V Arduino Compatible
Power supply indicator and Control indicator Red
You can control the 220V AC load, DC load also
There is a normally open and one normally close contact for Each Relay
 
It is  Channel 5Volt 10Amps Arduino Dual Relay Module Board. You can use it in microcontrollers such as Arduino, AVR, PIC, ARM etc.
It is can able to control or on/off various appliances and other types of equipment with large current with 2 numbers at a time.
Relay output maximum contact is AC250V 10A and DC5V 10A. One can connect a microcontroller with standard interface directly to it. It comes with Led indicator, so you can easily know the status of the apllicances using this module. It has a wide range of applications such as all MCU control, industrial sector, PLC control, smart home control, robotics etc.
This neat relay module features 2 x 5V relays rated at 10A/250V each. It is designed to switch up to for 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.
