Tutorial: How to Use SSR-40DA

The SSR-40DA is a solid state relay ideal for controlling AC electrical devices from 90 to 480V with a DC input of 3 to 32V and a maximum current of 40A. Useful for electronic and automation projects.

What you need

• SSR-40DA
• Arduino or Compatible Microcontroller
• Power Cable
• Control Cable

Steps

1. 1. Ensure the AC power supply is between 90 and 480V.
2. 2. Connect the AC power supply to the relay at pins AC1 and AC2.
3. 3. Connect the AC output to the device to be controlled.
4. 4. Connect the DC input to the microcontroller at VCC and GND.
5. 5. Connect the control signal to the IN pin of the relay.
6. 6. Load the source code onto the microcontroller.
7. 7. Run the program to control the relay.
8. 8. Check the proper operation of the relay.

Example code

void loop() {
 digitalWrite(2, HIGH);
 delay(1000);
 digitalWrite(2, LOW);
 delay(1000);
}

Mini project
