Siemens H8016-2400-4 Digital Energy Monitor

Siemens Digital Energy Monitor (DEM), Series 1000/2000, is an electrical-energy monitoring instrument designed for main and branch distribution panels in commercial and light-industrial facilities. The H8016-2400-4 designation places this unit in the 2400 A class of the DEM 2000 family, a high-current monitoring option used where large feeders must be tracked. The device collects voltage and current signals via built-in transducers and provides real-time data on energy use, enabling operators to observe load patterns across the monitored circuits. As documented in Siemens’ technical literature, the DEM 1000/2000 line is designed to integrate with APOGEE building-management components, enabling centralized energy monitoring within a broader automation strategy. Originating around the year 2000, the DEM line represented Siemens’ early digital energy-monitoring approach for integrated control systems, and it remains a reference point for historical building automation deployments. Common applications include monitoring feeders in offices, data centers, and light-industrial facilities where energy visibility supports optimization and demand-management decisions within an APOGEE-enabled ecosystem.
