Which of the red and white wires should be connected to the REXROTH solenoid valve in Germany

The German REXROTH solenoid valve plays an important role in industrial automation and fluid control systems, and correct wiring and installation methods are crucial for its normal operation. This article will elaborate on the connection method and correct installation method of the two wires of the solenoid valve.

1、 Connection of 2 wires for German REXROTH solenoid valve

German REXROTH solenoid valves usually have two wires, usually red and black. Before wiring, it is necessary to determine the operating voltage of the solenoid valve, which is commonly 12V or 24V DC voltage. It is important that DC voltage solenoid valves cannot be directly connected to 220V AC power sources.

1. Connect the red wire of the German REXROTH solenoid valve to the positive pole of the power supply. This is the control line of the solenoid valve, responsible for receiving control signals.

2. Connect the black wire of the German REXROTH solenoid valve to the negative terminal of the power supply. This is the common line of the solenoid valve, forming a current circuit.

During the wiring process, it is essential to ensure that the power is turned off to avoid the risk of electric shock. After completing the wiring, it should be checked whether the wiring is secure and confirmed to be correct before conducting a power test.

2、 The correct installation method of German REXROTH solenoid valve

In addition to proper wiring, the installation of solenoid valves is also crucial. Here are some suggested steps and precautions:

1. Choose the appropriate location: It is very important to choose a suitable installation location before installing the solenoid valve. Usually, solenoid valves should be installed in easily accessible and maintainable locations, while ensuring that the surrounding environment is clean, dry, and free of corrosive gases.

2. Installation direction: The installation direction of the solenoid valve is also important. In general, solenoid valves should be installed vertically with the coil facing upwards to ensure their normal operation. If space limitations require horizontal or inclined installation, the manufacturer's recommendations should be consulted.

3. Pipeline connection: When connecting pipelines, ensure that the connection is firm and well sealed to prevent leakage. Use appropriate sealing materials and connection methods, such as flanges, threads, etc.

4. Installation environment: Avoid installing solenoid valves in environments with severe vibration, impact, or temperature changes, as these environmental factors may affect their performance and lifespan.

5. Debugging and testing: After installation, perform necessary debugging and testing to ensure that the solenoid valve works properly. This includes checking the power connection, control signals, and whether the actions of the actuator are smooth.

6. Regular maintenance: To ensure the long-term stable operation of the solenoid valve, regular maintenance and inspection should be carried out. This includes cleaning up accumulated dust, inspecting the condition of seals and connectors, and replacing damaged components.

By following the above steps and precautions, the correct installation and efficient operation of the solenoid valve can be ensured. This not only helps to extend the service life of solenoid valves, but also ensures the stability and safety of industrial automation and fluid control systems.

1、 The function of the red and white wires of the solenoid valve

The German REXROTH solenoid valve is a controller that uses electromagnetic force to achieve gas or liquid flow control. Its working principle is to use the coil on the solenoid valve to generate a magnetic field and control pressure or liquid flow.

The red and white wires on the REXROTH solenoid valve in Germany are used for power supply. Among them, the red line is the positive pole and the white line is the negative pole. By connecting the power supply, the solenoid valve can work normally.

2、 Connection method of red and white wires for German REXROTH solenoid valve

The red and white wires of the German REXROTH solenoid valve need to be connected to an external power source in order to function properly. When wiring, the following points should be noted:

1. Connect the red line to the positive pole of the external power supply and the white line to the negative pole of the external power supply so that the solenoid valve can work properly.

2. When wiring, attention should be paid to matching the voltage of the power supply with the rated voltage of the German REXROTH solenoid valve itself, otherwise the solenoid valve may not work properly and may even burn out.

3. Before connecting the power supply, it is necessary to confirm the model and wiring method of the German REXROTH solenoid valve to avoid connecting the wrong wires, which may cause the solenoid valve to malfunction.

3、 Operation steps and precautions

Attention should be paid to the following points when wiring:

1. Firstly, it is necessary to ensure that the input voltage of the power supply matches the rated voltage of the solenoid valve, and do not connect it to the opposite polarity.

2. On the premise of confirming the correct direction of the solenoid valve, insert the red line into the positive pole of the power supply and the white line into the negative pole of the power supply.

3. After connection, pay attention to the working condition of the solenoid valve. If it is found that the solenoid valve is not working properly, it may be necessary to check whether the rated voltage and wiring are correct.

4. When maintaining the German REXROTH solenoid valve, attention should be paid to whether there are oxidation, aging, and other issues, and it should be replaced in a timely manner.

In short, the connection of the red and white wires of the German REXROTH solenoid valve is very simple. As long as it is correctly connected to the power supply, the solenoid valve can work normally. During operation, attention should be paid to the polarity and rated voltage of the power supply to avoid affecting the normal operation of the solenoid valve.
