• Industrial automation and control systems
• PLCs (Programmable Logic Controllers) and HMIs (Human-Machine Interfaces)
• Sensors, actuators, and relays
• Communication systems and industrial networking devices
• Test and measurement equipment

The Phoenix QUINT4-PS/1AC/24DC/10 features screw terminal connections for input and output wiring. Below is the pin configuration:

1. Mounting: Secure the power supply to a DIN rail or panel using the provided mounting clips. Ensure proper ventilation around the unit to prevent overheating.
2. Input Connection:
   • Connect the AC input wires to the L (Live) and N (Neutral) terminals.
   • Connect the ground wire to the PE terminal for safety.
3. Output Connection:
   • Connect the load to the + (Positive) and - (Negative) terminals.
   • Ensure the load does not exceed the maximum output current of 10A.
4. Signal Connection (Optional):
   • Use the DC OK terminal to monitor the output status. This can be connected to a PLC or indicator circuit.
   • Use the Remote terminal for remote on/off control if required.
5. Power On:
   • After verifying all connections, apply AC power to the input terminals. The power supply will automatically regulate the output to 24V DC.

• Input Voltage: Ensure the input voltage is within the specified range (100-240V AC). Operating outside this range may damage the unit.
• Load Capacity: Do not exceed the maximum output current of 10A. Use a fuse or circuit breaker for additional protection.
• Ventilation: Maintain at least 50mm of clearance around the unit for proper airflow.
• Wiring: Use appropriately rated wires for both input and output connections. Tighten all terminal screws securely to prevent loose connections.
• Monitoring: Utilize the DC OK signal to monitor the health of the power supply in critical applications.

The Phoenix QUINT4-PS/1AC/24DC/10 can be used to power an Arduino UNO. Below is an example wiring and code snippet:

1. Connect the + terminal of the power supply to the Arduino's VIN pin.
2. Connect the - terminal of the power supply to the Arduino's GND pin.

// Example code to monitor the DC OK signal from the power supply
const int dcOkPin = 2; // Connect DC OK signal to digital pin 2

void setup() {
  pinMode(dcOkPin, INPUT); // Set DC OK pin as input
  Serial.begin(9600);      // Initialize serial communication
}

void loop() {
  int dcOkStatus = digitalRead(dcOkPin); // Read DC OK signal
  if (dcOkStatus == HIGH) {
    Serial.println("Power supply is operating normally.");
  } else {
    Serial.println("Power supply output is not OK!");
  }
  delay(1000); // Wait for 1 second before checking again
}

1. Can this power supply be used with a 12V DC load?

   • No, the output voltage is fixed at 24V DC. Using it with a 12V load may damage the connected device.

2. What happens if the load exceeds 10A?

   • The power supply will activate overload protection and may shut down to prevent damage.

3. Is the power supply suitable for outdoor use?

   • No, this unit is designed for indoor use only. Use an enclosure for outdoor applications.

4. Can I connect multiple units in parallel for higher current?

   • Yes, the QUINT4 series supports parallel operation. Refer to the manufacturer's manual for detailed instructions.

By following this documentation, users can effectively integrate the Phoenix QUINT4-PS/1AC/24DC/10 into their systems for reliable and efficient power delivery.
