KS0263 keyestudio Single Solid State Relay Module

1. Introduction

Keyestudio single solid state relay is active at LOW level, that is to say, the input control signal is the low level (0-1.5 V), the relay is on; while the input control signal is high level (3-5 V), the relay is off.

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.

2. Performance Parameters

Electrical parameters:

Voltage	Static Current	Working Current	Trigger Voltage	Trigger Current
DC 5V	0mA	12.5mA	0-1.5V	2mA

Output port： AC 100V/2A

4. Sample Code

Download code : Code

int Relay = 3;

void setup()
{
   pinMode(Relay, OUTPUT);     //Set Pin3 as output
}

void loop()
{
   digitalWrite(Relay, HIGH);   //Turn off relay
   delay(1000);
   digitalWrite(Relay, LOW);    //Turn on relay
   delay(1000);
}

5. Result

Wiring as the above image, after powered-on, the solid state relay breaks for 1S and then connects for 1S, repeating alternately.
