Specifications and Features:-
 
 4 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 4 Channel 5Volt 10Amps Arduino 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 4 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 4 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.
