ARD2F LCD Display Smart Motor Protector
Inquire NowDescription
The ARD2F LCD Display Smart Motor Protector is a cutting-edge device designed to ensure comprehensive protection for motors in various industrial applications. This intelligent protector offers a wide range of measurement functions, including basic current parameters and advanced co-selection measurements such as voltage, power, phase sequence, and residual current (leakage). It effectively safeguards against critical issues like overload, phase failure, unbalance, and ground leakage, making it indispensable for industries such as coal, petrochemical, smelting, electric power, shipping, and civil construction.
Equipped with a user-friendly LCD display, the ARD2F provides real-time monitoring and fault event recording, allowing maintenance personnel to quickly identify and address any operational issues. Its robust design includes a standard RS485 communication interface supporting Modbus-RTU and Profibus-DP protocols, ensuring reliable communication with host systems. Additionally, it features a DC 4-20mA analog output for seamless integration with DCS systems, enabling efficient monitoring of field devices.
