DEHNrecord Alert sends status messages from surge protective devices (SPDs) to an evaluation system via Modbus TCP / RTU and enables forwarding to devices such as notebooks, tablets, smartphones, PCs or to the system control center. DEHNrecord Alert can be quickly put into operation using an app. The app transmits device information, e.g. article numbers, type designations and replacement modules, to DEHNrecord Alert. By sending this data to the user's evaluation device, maintenance and service work can be planned and carried out efficiently and cost-effectively.
