JXK-10 Hall Effect AC/DC Current Sensor User Manual

1. Introduction

The JXK-10 Perforated AC/DC Current Transmitter is an advanced device designed for precise current measurement. It integrates mutual inductance and transformation principles to convert large measured currents into proportional DC current or voltage signals, such as analog and switch signals. Utilizing zero flux, magnetic balance, and Hall effect technologies, it is suitable for measuring DC, AC, and pulse currents, as well as other arbitrary waveform currents. This manual provides essential information for the safe and effective installation and operation of your JXK-10 current sensor.

4. Setup and Installation

4.1 Installation Method

The JXK-10 current sensor can be installed using standard rail mounting or flat screw fixation. Ensure a secure and stable mounting location.

4.2 Wiring Instructions

Refer to the wiring diagram below for correct connections. Adhere strictly to the diagram to prevent damage to the transmitter.

• Input: Connect the current to be measured through the perforated hole.
• Output:
  
  • Out+: Output signal positive.
  • Out-: Output signal negative.
• Power Supply:
  
  • PWR L: Power supply live/positive.
  • PWR N: Power supply neutral/negative.
  • GND: Ground connection.

Note:

• Only the current output has reverse polarity protection (no damage but does not work). Other output signals are reversed, causing damage to the transmitter.
• The power supply must be wired strictly according to the wiring diagram.

4.3 Installation Considerations

1. Before using, carefully check and confirm the product quantity, model, and gauge according to the packing list and product label. Read the instruction manual thoroughly.
2. The operating environment should be free of conductive dust, corrosive gas, and strong shock or vibration.
3. The current transmitter has a bodyized structure and is not designed to be removable. Avoid collision and falls. Do not alter or tear off any stickers on the product.
4. When installing multiple current transmitters, the installation distance should be at least 10mm to prevent interference.
5. After wiring, verify all connections are correct before turning on the power supply and signal.

5. Operation

The JXK-10 current sensor operates based on the principle of electromagnetic induction. An internal high-precision current transformer converts the high-current signal from the field into standard process signals (e.g., 4-20mA, 0-10V, RS485). The input, output, and power supply are fully isolated from each other, ensuring stable and accurate signal output. Once correctly installed and powered, the sensor will provide a proportional output signal corresponding to the measured current.

6. Maintenance

The JXK-10 current sensor is designed for long-term, reliable operation with minimal maintenance. To ensure optimal performance:

• Keep the device clean and free from dust and debris.
• Avoid exposing the sensor to extreme temperatures or humidity outside its specified operating range.
• Regularly check wiring connections for tightness and signs of wear.
• Do not attempt to open or repair the device yourself, as this may void the warranty and cause further damage.

7. Troubleshooting

If you encounter issues with your JXK-10 current sensor, consider the following:

• No Output/Incorrect Reading:
  
  • Verify the power supply voltage is correct (DC24V or DC12V).
  • Check all wiring connections against the diagram (Figure 3).
  • Ensure the input current is within the specified measuring range for your model.
  • Confirm the output signal type (e.g., 4-20mA, 0-10V) matches your receiving equipment.
• Intermittent Readings:
  
  • Check for loose connections or damaged wiring.
  • Ensure the operating environment is free from strong electromagnetic interference.
  • Verify that the installation distance between multiple sensors is at least 10mm.
• Physical Damage:
  
  • If the device shows signs of physical damage, discontinue use and contact support.

8. User Tips

• For applications requiring high precision, ensure the sensor is installed in an environment free from excessive vibration.
• When selecting a model, carefully match the input current range and output signal type to your specific application requirements.
• Consider using appropriate shielding for signal cables in noisy electrical environments to maintain signal integrity.

9. Safety Information

Warning!

• Always disconnect power before installing or servicing the device.
• Ensure proper grounding to prevent electrical shock.
• Do not exceed the specified input current or supply voltage ratings.
• This product is intended for use by qualified personnel familiar with electrical installations and safety procedures.
• The device contains no user-serviceable parts. Unauthorized opening or modification may result in injury or damage to the device.
