Keyestudio Four-channel Solid State Relay Module

Introduction

Keyestudio four-channel solid state relay is a high level effective solid state relay, that is to say, the input control signals 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, its reliability is more higher, with the features of non-contact, long service life, fast and less outside interference.
The output control terminal of the keyestudio solid-state relay must be connected to the circuit, and its working current needs to be bigger than 50mA, so that the solid state relay can be disconnected normally.

Connection Diagram

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.
