Product Name: WDH-31-531 Intelligent Motor Control and Protection Management System

ELECNOVA WDH-31-531 intelligent motor control and management system is a brand new design motor controller for the open-door type and drawer type Motor Control Center(MCC Cabinet). The motor controller combines the protection and control function in a compact unit, which is available for the 35mm standard din rail installation. Besides the Modbus-RTU communication protocol, the WDH-31-531 is available for the Profitbus-DP and Modbus-TCP communication protocol, which covers the requirement of the major PLC such as Siemens and Omron brand. 

WDH-31-531  intelligent motor control and management system is equipped with the residual current protection and temperature protection without external accessories. There are two types of HMI for the WDH-31-531 as optional choice, the LCD display and the TFT colorful display. It’s the best choice for the intelligent motor control center(iMCC).
