DL3 Datalogger

Data logging with an extended range of functions
The DL3 Datalogger is used for logging data of up to 6 RESOL controllers and permits the visualisation via www.VBus.net and the parameterisation via RPT. Get a comprehensive overview of all controllers connected with the large full graphic display, all important settings are directly adjustable on the DL3. The integrated sensor and impulse inputs can measure and log temperatures – even without a controller. The DL3 is furthermore equipped with a BACnet functionality for BACnet conform transmission of data and can thus be used in a building management system.
