The DST-1R4P-N is a 4-channel optical isolator module, ideal for converting signals from 5V to 24V. Useful for automation projects and interfaces with PLC.

What you need

• DST-1R4P-N
• Arduino or compatible microcontroller
• 1 kΩ resistor
• 5-24V power supply cable

Steps

1. 1. Check the datasheet for the module specifications.
2. 2. Connect the module’s ground to the ground of your circuit.
3. 3. Connect the PLC’s NPN output to one of the module’s inputs.
4. 4. Connect a 1 kΩ resistor between the PLC’s NPN output and ground.
5. 5. Connect the module’s output to an Arduino input pin.
6. 6. Load the provided source code.
7. 7. Check that the module’s LED turns on when the PLC sends a signal.
8. 8. Repeat for all channels of the module.

Example code

```cpp
int ledPin = 13;
int inputPin = 2;

void setup() {
  pinMode(ledPin, OUTPUT);
  pinMode(inputPin, INPUT);
}

void loop() {
  digitalWrite(ledPin, digitalRead(inputPin));
}
```

Mini project

Create a simple control interface with a button and an LED. Connect the button to the PLC and the LED to the module’s output.

Common mistakes

• Do not follow the correct power connector.
• Connect the PLC directly to the module’s output without a resistor.
• Forget to check the ground pins.
• Do not use a compatible microcontroller.

Recommended accessories

• Arduino Uno
• Momentary Push Button
• LED
• 1 kΩ Resistor
