Crowtail- Solid-State Relay
Description
Crowtail- Solid-State Relay is a non-contact electronic switch module that has relay features.It has a maximum output of 240VAC/4A, with a switching speed less than 10ms. The featured LED indicates that the relay is on. It can be widely used in various areas such as computer peripheral interfaces, temperature/speed light adjustment, servo control, petrochemical, medical instrumentations, financial devices, coal, meters, traffic signals, etc.
Model: CT009739R
Features
- Compatible with both 3.3V and 5V control level
- Low switching latency（≤10ms）
- LED on-state indicator
- Level trigger
- Crowtail compatible
- Dimensions(mm):40.0(L)x20.0(W)x22.9(H)
Application Ideas
- Operations that require low-latency switching, e.g. stage light control
- Devices that require high stability, e.g. medical devices, traffic signals
- Situations that require explosion-proof, anticorrosion, moisture-proof, e.g. coal, chemical industries.
- For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.
Usage
1.Trigger signal voltage:
- Low level: 0-1.5 V the relay ON
- High level: 2.5-5 V the relay OFF
2.Connect Crowtail- Solid-State Relay to port D2(one button to D5) of Crowtail - Base Shield and plug it into Arduino/Crowduino.
3.Copy and paste code below to a new Arduino sketch, and upload it to your Arduino.
int relay=2;
int buttonPin=5;
int buttonState = 0;
void setup ()
{
pinMode(relay,OUTPUT);
pinMode(buttonPin, INPUT);
}
void loop()
{
buttonState = digitalRead(buttonPin);
if (buttonState == HIGH) {
digitalWrite(relay, LOW);
}
else {
digitalWrite(relay, HIGH);
}
}
4.When upload the code complete. Press the button, the yellow indicator light turns on , Relay on. Loosen the button, indicator light off and relay is off yet.
