4. Setup and Installation
4.1 Mounting
The JXK-10 current transformer can be mounted using either a 35mm DIN rail or screws. Ensure the mounting location is stable, free from excessive vibration, and within the specified operating temperature range.
4.2 Wiring Connections
Refer to the product label and the following general wiring diagram for correct connections. The device typically features screw terminals for power input, ground, and signal output.

- Power Supply (PWR): Connect the DC12V or DC24V power supply to the designated terminals (e.g., 24V and GND).
- Input Current (IN): Pass the conductor carrying the current to be measured through the central hole (22mm diameter) of the transformer. Ensure the current direction is consistent if polarity matters for your application.
- Output Signal (OUT): Connect the output terminals (e.g., Io+, Io-) to your monitoring or control device. The output signal will be 0-5V, proportional to the measured current.

5. Operating Instructions
Once properly installed and wired, the JXK-10 current transformer operates automatically. The device converts the measured AC or DC current into a proportional 0-5V analog output signal. This signal can then be read by a PLC, microcontroller, or other data acquisition system.
- Ensure the input current is within the specified range of your JXK-10 model (e.g., 0-20A, 0-50A, 0-100A, etc.).
- Monitor the 0-5V output signal. A 0V output typically indicates no current, while 5V indicates the maximum rated current for your specific model.
- For precise measurements, ensure the power supply to the JXK-10 is stable and within its specified voltage range.
