Functional characteristics
Comprehensive protection function: with overload, short circuit, phase loss, grounding fault and other protection functions, can effectively protect the motor from various faults. For example, by monitoring the current, voltage and other parameters of the motor, when there is an overload situation, the relay can act in time to cut off the power and prevent the motor from being damaged due to overheating.
Accurate temperature monitoring: Integrated multiple RTD inputs, can be connected to 100 ohms nickel, 120 ohms nickel, 10 ohms copper and 100 ohms platinum and other three-wire RTDS, accurate monitoring of the actual temperature and hot spot temperature of the motor system, help to detect the motor overheating problem in advance, avoid the fault caused by excessive temperature.
Powerful communication capability: support a variety of communication protocols, such as Modbus RTU, etc., can be easily integrated with PLC, DCS and other control systems to achieve remote monitoring and management. Users can view the running status and parameter information of the motor in real time through the upper computer software, and carry out remote control and parameter setting.
User-friendly front panel design: Equipped with an enhanced front panel with a large LCD display that can display 40 characters, and can clearly present information such as diagnostic messages, motor and output status. At the same time, it also has a numeric keyboard, control and programming keys, which is convenient for users to perform local operation and parameter setting.

Application scenario: The relay is designed for medium voltage motor, widely used in industrial fields, such as manufacturing, petrochemical, electric power, water treatment, metallurgy and other industries, suitable for various types of large and medium-sized three-phase motor and its related system control and protection, can improve the reliability and efficiency of motor operation, reduce downtime, reduce maintenance costs.
