12 Volt 2 Channel Relay Module board
These are optically isolated relay modules having 12 Volt cube Relays. The relays are driven by an Opto-coupler which provides isolation between your Micro-controller, Arduino or Raspberry Pi & the relay thus making this module better than the modules having transistor or ULN2003 IC as drivers.
This is a 2 channel Relay Module with output relay contacts of 7 amperes at 250 volts. You can use it easily with any Microcontroller, Arduino or Single Board Computers (SBC) like Raspberry Pi and Beagle bone. You can even use this module with digital IC’s like LM555 and HT12D Decoder IC.
Applications Of Relay Board
- support all MCU control.
- the industrial sector
- PLC control
- smart home control
