Optocoupler is also very valuable because it isolates the power PWM dimming driver from the eHouse controller so it is much safer to connect without the need for a common voltage for controller and driver.
Optocoupler pia ni muhimu sana kwa sababu hutenga nguvu PWM dimming dereva kutoka mtawala eHouse hivyo ni salama sana kwa kuunganisha bila ya haja ya voltage kawaida kwa mtawala na dereva .
