Optoisolated Relay Modules - 3.3V - Various Configurations
Now available from PMD Way are a huge range of popular and often-used general relay modules with 3.3V coils.
Ideal for use with Raspberry Pi or other projects that have a lower 3.3V GPIO control system.
You can select the number of relays per board using the options menu. LEDs on relay board show relay on/off status.
Furthermore you can select whether the relay is controlled by a high or low signal via the jumper shunt on each board. Awesome!
- All relays handle AC 250V/10A, DC 30V/10A
