I: Overview of junction box for load cell

The junction box for load cell is a device that converts the wiring between the load cell and the display instrument, and its function is to complete the electrical signal connection between the load cell and the display instrument. The correctness of the connection directly affects the display results of the weighing instrument.

II: Wiring principle of junction box for load cell

The wiring principle of the junction box for load cell is to convert the output signal of the load cell into a standard signal, and then connect it to the display instrument through a cable. There are two cables in the junction box for load cell, one connected to the power line and the other connected to the signal output line of ip65 electrical box. In theip65 electrical box, connecting the cable to the corresponding terminal post can be used for wiring.

III: How to connect wires

1. Connect the power cord

The power cord is divided into two input terminals and two output terminals, with the input terminal (red) connected to the positive pole of the power supply and the output terminal (black) connected to the negative pole of the power supply. After connecting the power cord to the input terminal, connect the power supply through the output terminal. When connecting, be careful not to reverse the positive and negative poles of the power supply, otherwise it may burn out the sensor.

2. Connect the signal output line

Connect the signal output line to the output port of the junction box for load cell. It should be noted that the polarity of the output line cannot be wrong, otherwise it will not generate correct weighing data.

IV: Precautions

1. Before wiring, it is necessary to check whether the voltage of the power supply and sensor matches;

2. When connecting, ensure that the connection between the sensor and the load cell summing board is firm and stable;

3. It is necessary to ensure that the power supply is connected correctly, and the positive and negative poles of the power supply cannot be reversed;

4. When wiring, it is necessary to disconnect the power supply first to avoid the risk of electric shock;

5. After wiring, be sure to check if the wiring is correct to avoid making mistakes.

【 Conclusion 】

Through the introduction of the above content, we can understand the wiring method of the load cell summing board, including the connection methods and precautions of power lines, signal output lines, etc. These contents are very important for personnel using weighing instruments. Only the correct connection method can ensure the accuracy of the weighing instrument.
