Humidity: It can withstand an environment with a relative humidity of up to 95%, provided there is no condensation. Others: The weight is approximately 0.3kg.

Application Areas Industrial Automation: It is used for the control and monitoring of production lines, manufacturing processes, and mechanical equipment, achieving precise control and optimization of the production process, and improving production efficiency and product quality. Process Control: In process industries such as chemical, pharmaceutical, and petroleum industries, it is used to monitor and control various parameters in the production process, such as temperature, pressure, flow rate, liquid level, etc., to ensure the stability and safety of the production process. Energy Production: It can be applied in places such as power plants and substations to monitor and control the operating status of equipment such as generator sets, transformers, and transmission lines, ensuring the stable supply of energy. Environmental Control Systems: It is used in building automation and environmental control systems, such as controlling HVAC systems, lighting systems, elevator systems, etc., to achieve intelligent management of buildings and energy conservation. Data Acquisition and Communication: As a data acquisition module, it can collect analog data of various field devices and transmit the data to a host computer or other control systems through a communication network, realizing remote monitoring and management.

Faults and Solutions: Abnormal Input Signal Fault Description: The module cannot correctly read the millivolt signal input by the sensor, or the read value has a large deviation from the actual value. Solution: First, check whether the connection between the sensor and the module is loose, open-circuited, or short-circuited, and ensure a reliable connection. Then confirm whether the sensor is working properly, which can be tested by replacing it with a normal sensor of the same type. If the sensor is normal, check whether the input range setting of the module matches the output signal range of the sensor. If there is an error, reset the correct range.

Abnormal Output Signal Fault Description: The analog signal output by the module is unstable, distorted, or the module cannot output a signal. Solution: Check whether the output connection line of the module is in good condition, and whether there is any damage or poor contact. Check the configuration parameters of the module to confirm whether the settings of the output signal type, range, etc. are correct. If the output signal is still abnormal, try to reset or reinitialize the module to see if it can return to normal. If the problem still exists, it may be that the output circuit inside the module has a fault, and professional maintenance personnel need to be contacted for repair or module replacement.

Communication Fault Fault Description: The module cannot communicate normally with the host computer or other devices, resulting in the inability to transmit or receive data. Solution: Check the communication line, including cables, plugs, etc., to ensure that they are correctly connected and not damaged. Confirm whether the communication parameter settings, such as baud rate, data bits, stop bits, parity, etc., are consistent with those of other devices. Try to restart the module and related communication devices to see if communication can be restored. If it is network communication, check whether the network configuration and permission settings are correct. If none of the above methods work, it may be that the communication interface of the module has a fault, and professional personnel need to be consulted for repair.

Module Overheating Fault Description: The module overheats during operation, which may lead to a decline in performance or a fault. Solution: Check the installation environment of the module to ensure that there is enough heat dissipation space around it and it is not blocked by sundries. Clean the surface of the module to prevent dust accumulation from affecting heat dissipation. Confirm whether the ambient temperature is too high. If the ambient temperature exceeds the operating temperature range of the module, measures need to be taken to reduce the ambient temperature, such as adding cooling devices like air conditioners or fans. If the module is still overheating, it may be that the internal heat dissipation components have a fault, and repair or replacement is required.

Power Supply Fault Fault Description: The module cannot start normally or its operation is unstable, which may be due to a problem with the power supply. Solution: Check the power input line to ensure that the power supply voltage is normal and the voltage fluctuation is within the allowable range of the module. Check whether the power plug and socket are in good contact and there is no looseness or oxidation. If a DC power supply is used, check whether the positive and negative poles of the power supply are correctly connected. If the power supply line is normal, it may be that the power supply circuit inside the module has a fault, and professional personnel need to be consulted for repair or replacement of the power supply module.
