The 8 Relay Module comes with Opto-insulated inputs and can be driven by an input voltage of 3-24V DC. The relays are 5V models, needing a 5V DC power supply to work. The maximum switchable load is 10A at 250V AC or 30V DC (max.).

The 2 different power supply modes of the 2 Relay Modules can be selected by jumpers.

Our 8 Relay Module needs about 70mA per activated relay (at 5V).

Please make sure, your power supply is strong enough.

Because of the optocoupler is the necessary input current just about 1mA (but shouldn’t exceed 20mA), and the relay board can be directly controlled by any development board like Arduino or Raspberry, and also by every available microcontroller (Atmel, ST, PIC etc.) with a logic level of 3V or above.

The dimensions are 55 (W) 138 (L) 19 (H) mm.

Other relay modules with 2 relays, 4 relays and 8 relays are also available.

High-Current relay modules (30A) are available as well.

Finally, we offer relay modules for the ESP-01 IoT module, WeMos D1 Mini, remote-controlled relays, and a WiFi 4-Channel relay DIY kit.

    Item arrived quicker than i tought. Well built, nice product!I am a bit disapointed that the relays are activated at low signal (GROUND) , it means you have to use a NPN transistor to use an high output (VCC) of the raspberry, this prevent the relay from being ON for no reason after a reboot before program initiate… BUT, this was clearly indicated in the description, ordered too fast, my fault, not a big deal im using transitor
