ARD2F Motor Protection Controller

General

ARD2F smart motor protectors can protect motors from many faults during the motor running and display the running state clearly and intuitively through LCD.The protector has RS485 remote communication interface and DC4-20mA analog output, which is convenient to form a network system together with control machines like PLC and PC.
