From metering to smarthome to industry:
five good reasons for using photo relays


From safety applications to PLC industrial control and e-mobility charging stations.
Even smaller, even quieter and for higher currents.

Wherever galvanic isolation between control and operating circuit is required, photo relays are used.

Five good reasons for using photo relays in metering, smarthome and industrial applications:

  1. Switch silently and without contact bounce
  2. Wear-free and maintenance-free
  3. Save up to 80 % space compared to mechanical relays
  4. Are safe from electromagnetic interference
  5. Are easily and directly controlled via the GPIO port of an MCU

From big to tiny - check out the wide range of photo relays in our quick guide.
