Introduction

Keyestudio four-channel solid state relay is active at HIGH level, that is to say, the input control signal is the low level (0-2.5 V), the relay is off; while the input control signal is high level (3.3-5 V), the relay is on.

Solid State Relay is a new kind of contactless switching device, which is composed of all solid state electronic components.

Compared with the electromagnetic relay, it has higher reliability, with the features of non-contact, long service life, fast speed and less outside interference.
The output control terminal of keyestudio solid-state relay must be connected to the circuit, can only be AC (Alternating Current) ,so that the solid state relay can be disconnected normally.

Sample Code

int BASE = 3 ;  //The first relay I/O port
int NUM = 4;   //Total number of relay
void setup()
{
   for (int i = BASE; i < BASE + NUM; i ++) 
   {
     pinMode(i, OUTPUT);   //Set the digital I/O port to output
   }
}

void loop()
{
   for (int i = BASE; i < BASE + NUM; i ++) 
   {
     digitalWrite(i, HIGH);    //Set the digital I/O port outputs to "HIGH", that is, gradually open
     delay(200);        //delay
   }
   for (int i = BASE; i < BASE + NUM; i ++) 
   {
     digitalWrite(i, LOW);    //Set the digital I/O port outputs to "LOW", that is, gradually close relay
     delay(200);        //delay
   }  
}


Result

Wiring as the above image,after powered-on,four-channel solid state relay is first connected and then broken successively,repeating alternately.
