Used with 12v push buttons to control 240v lightning.
Really cool and so easy to use! I ordered single module to test it and ended up with this one as I wanted to control 2x under cabinet lights and 1x ceiling LED in the living room. All devices are smart but I wanted to have an option to ON/OFF them in case of Home Assistant failure. So I figured out, that the easiest and safest way will be to used 12v push buttons in the worktop and they worked really well with this device. Just needed to swap the yellow jumper to low voltage as it didn't work at the beginning. Really cool device.

All good so far, it appears to work well.
Appears to work very well I'm only holding off from a full five stars because I don't know how long it will last.

Worked out of the box without issues
This a great interface board. The board needs a 5v DC supply for the relay coils but are driven by drivers which can be triggered using 3,3v so ideal for IOT devices like Arduino, ESP, Rasoberry Pi etc It can also use either logic hi or low switching by the use of jumpers on board.

Beware
Beware, this board does NOT provide optical isolation.

Funciona perfecto con raspberry pi

Uso queste schede per separare l'out. delle centrali antifurto dall'inp. dei combinatori telefonici. Utilissimi i led che indicano il funzionamento dei quattro canali. Le schede funzionano bene e costano molto meno di quelle del mio fornitore abituale in Italia. Ne acquisterò ancora. Soddisfatto anche della puntualità della consegna (coma da abitudine Amazon).

Die Auswahlmöglichkeit Low oder High level trigger bietet vielseitige Einsatzmöglichkeiten. Perfekt wäre noch die Angabe der Abstände der Bohrungen.

5V versionen. Helt ok reläkort som klarar att aktiveras med styrspännig under 2V. Vid så låg styrspänning bottnar inte optokopplaren vilket leder till spänningsfall och lägre spänning till reläspolen, men den verkar klara att dra ändå. Med 3,3V styrspännig drar ingången ca 2mA och relät sluter utan problem.
