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 din masyadong mahalaga dahil ito isolates ang kapangyarihan PWM dimming driver mula sa eHouse controller upang ito ay mas ligtas upang kumonekta nang walang pangangailangan para sa isang karaniwang boltahe para sa controller at driver .
