Topic: OptoMOS or PhotoMOS-Relay (Read 2263 times) previous topic - next topic


I am looking for help regarding relays.
So I want to be able to output from an Arduino Pin (40mA) a trigger that than makes an OptoMOS or PhotoMOS-Relay switch and than closes a circuit that needs up to 4A and between 3-24 V.
This is for controlling/switching on/off via Arduino a motor.
It would be fantastic if anybody could tell me a product that would be capable to do this.
Thanks for the time!


Often you just need to know the right words to search for. In your case you want a DC SSR (solid state relay)


Thanks for the response. I knew I was looking for that. But I got lost finding an actual product that has my specifications. Is there one anyone can recommend. A link to a product?
