How to Use 6 Channel DIN Fused DC Distribution: Examples, Pinouts, and Specs

The 6 Channel DIN Fused DC Distribution unit is a versatile and reliable component designed to manage and distribute DC power across six independent channels. Each channel is equipped with a built-in fuse to provide overcurrent protection, ensuring the safety and longevity of connected devices. This unit is typically mounted on a DIN rail, making it ideal for use in industrial control panels, automation systems, and other electrical installations requiring organized and protected DC power distribution.

• Industrial automation systems
• Power distribution in control panels
• Renewable energy systems (e.g., solar power installations)
• Telecommunications equipment
• Low-voltage DC lighting systems
• Any application requiring organized and fused DC power distribution

The following table outlines the key technical details of the 6 Channel DIN Fused DC Distribution unit:

The unit features screw terminals for input and output connections. The pin configuration is as follows:

1. Mounting the Unit: Securely attach the unit to a 35mm DIN rail in your electrical panel.
2. Connecting the Input:
   • Connect the positive DC supply to the Input (+) terminal.
   • Connect the negative DC supply (ground) to the Input (-) terminal.
3. Connecting the Outputs:
   • For each device or circuit, connect the positive wire to the corresponding Output (+) terminal (e.g., Output 1 (+) for Channel 1).
   • Connect the negative wire to the corresponding Output (-) terminal (shared ground).
4. Fuse Installation:
   • Insert the appropriate blade fuse (up to 10A) into the fuse holder for each channel.
   • Ensure the fuse rating matches the current requirements of the connected device.
5. Power On:
   • After verifying all connections, power on the DC supply. The unit will distribute power to the connected devices.

• Fuse Selection: Always use fuses with a rating slightly higher than the normal operating current of the connected device but below the maximum channel rating (10A).
• Wire Gauge: Use appropriately rated wires for the input and output connections to handle the expected current without overheating.
• Overcurrent Protection: The built-in fuses provide overcurrent protection, but additional circuit breakers or protection devices may be required for the input supply.
• Ventilation: Ensure adequate ventilation around the unit to prevent overheating, especially in high-current applications.
• Polarity: Double-check the polarity of all connections to avoid damage to the unit or connected devices.

The 6 Channel DIN Fused DC Distribution unit can be used to power an Arduino UNO and other peripherals. Below is an example of how to connect the unit:

1. Connect a 12V DC power supply to the Input (+) and Input (-) terminals.
2. Insert a 1A fuse into the fuse holder for Channel 1.
3. Connect the Output 1 (+) terminal to the VIN pin of the Arduino UNO.
4. Connect the Output 1 (-) terminal to the GND pin of the Arduino UNO.

Here is a simple Arduino sketch to blink an LED connected to the Arduino:

// This sketch blinks an LED connected to pin 13 of the Arduino UNO.
// Ensure the Arduino is powered via the 6 Channel DIN Fused DC Distribution unit.

void setup() {
  pinMode(13, OUTPUT); // Set pin 13 as an output
}

void loop() {
  digitalWrite(13, HIGH); // Turn the LED on
  delay(1000);            // Wait for 1 second
  digitalWrite(13, LOW);  // Turn the LED off
  delay(1000);            // Wait for 1 second
}

1. No Power to Outputs:

   • Cause: Blown fuse or incorrect input connection.
   • Solution: Check and replace the fuse for the affected channel. Verify the input connections.

2. Overheating:

   • Cause: Exceeding the maximum current rating or poor ventilation.
   • Solution: Reduce the load on the channels and ensure proper ventilation around the unit.

3. Device Not Powering On:

   • Cause: Incorrect polarity or insufficient fuse rating.
   • Solution: Verify the polarity of the connections and ensure the fuse rating matches the device's current requirements.

4. Fuse Blowing Frequently:

   • Cause: Overcurrent or short circuit in the connected device.
   • Solution: Inspect the connected device for faults and ensure the current draw does not exceed the fuse rating.

Q: Can I use this unit with an AC power supply?
A: No, this unit is designed for DC power only. Using an AC supply may damage the unit and connected devices.

Q: What type of fuses should I use?
A: Use standard blade fuses (e.g., ATC/ATO) with a rating appropriate for the connected device, up to 10A per channel.

Q: Can I connect multiple devices to a single channel?
A: Yes, but ensure the total current draw does not exceed the channel's fuse rating or the wire's capacity.

Q: Is the unit waterproof?
A: No, the unit is not waterproof. It should be installed in a dry, protected environment.
