<br>
==Introduction==
Keyestudio eight-channel solid state relay is '''active at HIGH''' level, that is to say, the input control signal is the high level (3.3-5 V), the relay is on; while the input control signal is high level (0-2.5 V), the relay is off. <br>

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

Compared with the electromagnetic relay, it has higher reliability, with the features of non-contact, long service life, fast speed and less outside interference. <br>
<span style=color:red> 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. </span><br>

==Sample Code==
<pre>
int BASE = 3 ;  //The first relay I/O port
int NUM = 8 ;  //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 relay
     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
   }  
}
</pre>

<br>
==Result==
Wiring as the above image, after powered-on, eight-channel solid state relays are first connected and then broken successively,repeating alternately.<br>
