El relé viene con 8 relés de activación de 5 V de un solo canal, listo para controlar 250 V CA a 10 A. Aislamiento adicional con optoacoplador en el extremo frontal del control, y la lógica de activación para relé se puede configurar a través de un mini puente.
Disparador de nivel alto/bajo:
- 1. Gatillo de bajo nivel cuando el puente y el cortocircuito L;
- 2. Gatillo de alto nivel cuando el puente y el cortocircuito H.
El paquete incluye:
1 módulo de relé de ocho canales de 5 V con módulo optoacoplador
Interfaz de entrada:
CC +: conecta a la potencia positiva (según el rango de voltaje del relé) CC-: conecta a la potencia negativa: pin de disparo del módulo de relé (disparador de nivel alto o bajo opcional)
Salida de relé:
Normalmente abierto (NO): pin normalmente abierto del relé. Ningún pin no se conecta al pin COM cuando el relé se apaga. Sin pin se conecta al pin COM cuando se enciende el relé; pin común (COM): Pin común del relé; normalmente cerrado (NC): normalmente cierra el pin del relé.

I've bought 4 of these, only because it's my only option without waiting 30-40 days for a better product direct from Asia.The 1st was DOA (1 or more channels did not work at all).The 2nd worked initially, but because I slightly "overtightened" (wasn't really too tight) the DC+ input terminal, the connection from that terminal to the board became loose and the unit would not reliably stay on. These things are made SOOOO cheaply!!!The 3rd and 4th were DOA (each had a different channel non-functional). I ordered 2 even though I just needed one, because I needed to work on it this weekend and knew my chances of getting a bad one were high. Guess I should have ordered 10 and hoped for 10% success rate?So now I'm waiting on replacements for the last couple of DOA units. And even if they work, I'll be forever worried that something is going to break and I'll have to take my entire project apart to replace the relay. What are the odds something like this will last 10 years or even 1 year, given how incredibly poorly it is made the the unbelievably high failure rate?I would gladly pay more for something that just works, but this seems to be the only option other than waiting a month or more. (And I will be ordering a couple of those to have on hand, but for now I can't wait that long to use them.)

Update: I'm dumb. Not the manufacture or Amazons fault, for the failures. I made a miscalculation and was able to fix it. Even the company reached out to see what was wrong!!!Pre purchased these for a project that took a year and a half to finish. I am finally finishing up just to come to find out none of them work even with direct current to the coil leads. Out $15 and have to order something different. Will update as needed. At current time stay away from the single pack ones.
