4 Channel 12 Volt Isolated Relay Module

12 Volts 4 Channel Optically Isolated Relay Module

These are optically isolated relay modules having 12 Volt cube Relays. The relays in this 4 channel 12 volts isolated relay module are driven by a Opto-coupler which provides isolation between your Micro-controller, Arduino or Raspberry Pi & the relay thus making this module better that the modules having transistor or ULN2003 IC as drivers.

This is a 4 channel Isolated Relay Module with output relay contacts of 10 ampere 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 of HT12D.

We have various types of Relay & SSR Modules which you can use to control appliances. Check out our complete collection of MOSFET, SSR & Relay Modules. We also have various types of high quality Relays & SSR.
