Profibus-DP Controller 3 Phase Motor Overload Protection

Product Name: WDH-31-500 Profibus-DP communication fan controller 3 phase motor overload protection

The motor protection controller can provide up to 12 programmable digital inputs (optional dry and wet contacts), 7 programmable relay outputs, all programmable inputs and outputs, all of which meet the requirements of different protection control requirements on site. The function can set the alarm value and the action value at the same time, and can respectively retreat and retreat, and the protection parameters can be adjusted by the professional according to the actual working condition of the field motor, and the power failure is not lost.
