2. Application Case

1. Central air conditioning temperature control system

In the central air conditioning system, the FX5-4AD module monitors the ambient temperature in real time by connecting the temperature sensor. The system requires that the unit will not be started when the temperature is lower than 12°C, the two units will be started in sequence when the temperature is higher than 12°C, one of the units will be stopped when the temperature is lower than 7.5°C, and the system will give an ultra-low temperature alarm when the temperature is lower than 5°C. Through the high-precision data acquisition and conversion functions of the FX5-4AD module, the efficient monitoring of the ambient temperature and the precise execution of the control logic are realized.

1. Industrial Process Control System

FX5-4AD module is used to collect analog signals of various sensors (such as pressure sensors, liquid level sensors, etc.) in industrial process control systems. Through the analysis and processing of the collected data, the PLC system can adjust the control parameters in real time to ensure the stability and efficiency of the production process. For example, in the chemical production process, the FX5-4AD module can monitor the temperature and pressure in the reactor, and adjust the heating power and material delivery amount according to the preset control logic, so as to improve the production quality and efficiency.

3. Usage

1. Module connection and numbering

The FX5-4AD module can be installed on the right side of the FX5 series PLC basic unit, and the number is 0~7 from the beginning closest to the basic unit. When connecting, pay attention to the relationship between the total points of the module and the points of the basic unit to ensure the correctness of the system configuration.

1. Buffer Register (BFM) Allocation

Data communication between the FX5-4AD module and the PLC basic unit is performed through FROM instruction and TO instruction, and both read and write operations are performed for the buffer register BFM of the module. The BFM consists of 32 16-bit registers for storing data exchange information with the module. The specific BFM distribution table should be formulated according to the actual application requirements.

Conclusion

FX5-4AD Mitsubishi PLC analog module has been widely used in the field of industrial automation control for its high precision, multi-channel, easy installation and high reliability. Through this module, the PLC system can efficiently collect and process analog data, realize complex control logic, and improve production efficiency and system stability. In the future, with the continuous development of industrial automation technology, the application prospect of FX5-4AD module will be broader.

Plain language sourcing guide for FX5-4AD Mitsubishi PLC Analog Module

Start with the full model name. Check the brand name. Check the part number. Check the code on the old unit. These small checks help you avoid a wrong order.

Take one clear photo of the front label. Take one photo of the side label. If the part has a cable, plug, port, seal, coil, or screen, take a photo of that area too.

Tell us the quantity you need. Tell us your country. Tell us the date when the plant needs the part. We can then check stock, lead time, safe packing, and the best shipping plan.

If the exact model is no longer made, do not guess. Send the old model and the use case. LEHIY can compare close options and explain which choice is safer for repair work.

Use simple order notes. Write the model in one line. Write the quantity in one line. Write the delivery country in one line. This helps our team reply faster.

Check the old part before removal. Look at the label. Look at the connector. Look at the mounting size. Look at the voltage or pressure rating if it is shown.

Do not rely on a short nickname for a part. Many industrial items have close versions. A small suffix can change the plug, output, range, or software setting.

Ask for a stock check if the plant is stopped. Ask for a lead time if the order is planned. Ask for packing photos if the part is fragile or heavy.

For a replacement order, tell us what failed. Tell us where the part is used. Tell us if an equal model is acceptable. This makes the first answer more useful.

For repeat orders, send the last invoice, old label, or old packing photo. The same reference can help us match the correct product again.

For urgent service, keep the message simple. One model, one quantity, one photo, and one delivery target are enough for a fast first check.
