The output capacity can meet the driving needs of most industrial on-site control equipment, realizing precise start-stop, forward-reverse rotation and other control operations of the equipment.

Current Monitoring: For specific circuits, the rated working current can reach 10A (the "10" in "M405A" in the model is related to this rated current). It can monitor the current in the circuit in real-time. Through high-precision current sensors, it can accurately measure the current value and quickly respond to abnormal current conditions such as overcurrent and short circuit.

Voltage Monitoring: Can accurately monitor three-phase AC voltage or DC voltage, and can adapt to different types of power supply systems. The voltage measurement range is set according to industrial standards, with high measurement accuracy, and can timely detect abnormal conditions such as voltage fluctuations, overvoltage, and undervoltage, providing reliable guarantee for the stable operation of the power system.

Power Monitoring: Can calculate and monitor parameters such as active power, reactive power, and apparent power. By mastering these power parameters in real-time, users can clearly understand the power consumption and power factor status of the system, which helps optimize energy utilization, reduce operating costs, and achieve the production goal of high efficiency and energy saving.

Electric Energy Metering: Has the function of cumulative electric energy metering, which can accurately count the electric energy usage within a period of time, providing accurate data support for energy management and cost accounting, and meeting the strict requirements of industrial enterprises for electric energy metering.

Communication Protocols: Supports multiple mainstream industrial communication protocols, such as Modbus, Ethernet/IP, DeviceNet, etc. It can realize seamless communication with industrial automation equipment of different brands and types, facilitating the construction of heterogeneous industrial automation networks, realizing rapid data exchange and sharing, and ensuring the collaborative work of all parts of the system.

Communication Interfaces: Equipped with rich communication interfaces, including RS-485 serial ports, Ethernet interfaces, etc. The RS-485 interface has a long communication distance and strong anti-interference ability, which is suitable for harsh communication environments in industrial sites and can connect devices such as smart electric meters, sensors, and actuators; the Ethernet interface provides high-speed and stable data transmission capabilities, meeting communication scenarios with large data volume and high real-time requirements, and facilitating remote data interaction and monitoring management with upper computers and cloud platforms.

Control Methods: Provides a variety of flexible control methods, such as control logic based on parameters such as voltage, current, power, and time. Users can freely choose and combine through programming or parameter settings according to actual production process requirements, realizing precise regulation of equipment operating status to adapt to the diverse control requirements of different industrial application scenarios.

Response Time: The response time of control commands is extremely short. From receiving the control signal to executing the corresponding action, it is usually within milliseconds, ensuring that the system can quickly respond to various changes, effectively improving the dynamic performance and real-time control ability of the system, and ensuring the efficiency and stability of the industrial production process.

Overcurrent Protection: When the module detects that the current in the circuit exceeds the rated value, it will quickly trigger the overcurrent protection mechanism, automatically cut off the relevant circuit or limit the current output, preventing damage to the module itself and connected equipment due to overcurrent. The protection action time is short, which can effectively avoid the expansion of faults.

Short-Circuit Protection: Once a short-circuit fault at the output end is detected, the short-circuit protection function takes effect immediately, cutting off the power supply in a very short time to avoid irreversible damage to the equipment caused by excessive short-circuit current and ensure the safe operation of the system.

Overvoltage Protection: When the input voltage or the internal circuit voltage of the module rises abnormally and exceeds the set safety threshold, the overvoltage protection function is activated. It protects the sensitive components inside the module through measures such as voltage reduction and voltage limitation, preventing damage due to overvoltage and maintaining the normal working state of the system.

Undervoltage Protection: When the input voltage is lower than the normal working range, the undervoltage protection function is turned on, timely sending out an alarm signal and taking corresponding measures (such as stopping the operation of some non-critical equipment) to prevent the module and connected equipment from working in a low-voltage state, which may affect equipment performance or cause equipment damage, ensuring the reliability of the system operation.

Overheating Protection: The module is integrated with a high-precision temperature sensor to monitor the working temperature of the module in real-time. When the temperature exceeds the maximum allowable value, the overheating protection mechanism is automatically activated. It makes the module temperature return to the normal range by means of accelerating heat dissipation through cooling fans, reducing the working power of the module, or temporarily stopping work, avoiding performance degradation or damage of components due to overheating, and prolonging the service life of the module.

Operating Temperature: Can work stably within a relatively wide temperature range. Usually, the operating temperature range is -20°C to +60°C (specific range is subject to the product manual). It can adapt to the temperature conditions of different industrial places, whether it is a high-temperature production workshop or a low-temperature storage environment, it can ensure the normal operation of the module and protect the industrial automation system from the impact of temperature changes.

Relative Humidity: Can operate reliably in an environment with a relative humidity of 5%-95% (non-condensing state), with good moisture-proof performance. It is suitable for industrial environments with high humidity such as textile factories and food processing factories, effectively avoiding circuit short circuits, corrosion and other faults caused by humidity problems, and ensuring long-term stable operation of the module.

Protection Level: Generally, the protection level is IP20, which is suitable for indoor installation environments. It can prevent the intrusion of solid foreign objects larger than 12mm and avoid damage to the module caused by dust accumulation; at the same time, direct contact with liquids should be avoided. In practical applications, it is often installed in a control cabinet, and the overall protection effect is further improved by means of the protective measures of the control cabinet to adapt to the complex and changeable industrial on-site environment.
