• Communications via Profibus-DP, LONWORKS or RS 485 (upon model)
• Measurement of current, voltage, active, reactive and apparent power, 
  power factor, line frequency and energy, harmonic up to 15th order
• Simultaneous display 4 measurement values with 9 digit energy
• LED display for cleary and long distance from panel. 
• Storage of selected measurement values (continuous or events triggered 
  recording of measurement values)
• Programmable ratios for current and voltage transformers
• Two limit value contacts (assigned as desired to measurement values)
• 2 analog output or 4 analog output depend on model. 
• 2 pulse output or builtin memory for data logger depend on model.
