Measurements are Analog Inputs (energy, power, demand, volts, amps, power factor, frequency), setup is in eleven writable Analog Values (system type, CT and PT ratios, system voltage, demand intervals), and alerts are Binary Inputs that also roll up into AI 52. The E50H5 also has three Trend_Log objects.",
