Key Features
Measures voltage, current, energy, frequency, power, active power, reactive power, power factor, active factor and reactive power compensation.
Supports Rogowski coils and current-voltage converters with a 333 mV interface; current measurement supports max. 3 + neutral conductor.
Rated supply voltage is 24 V DC, with a permissible range of 19.2 V DC to 28.8 V DC; usable BaseUnit is BU type U0.
Provides cyclic and acyclic measured value access, fixed and freely definable measured value sets, and a 50 ms typical cycle time for consistent updates of all channels.
Configurable via GSD file; STEP 7 V16 or higher with HSP is supported. PROFINET GSD revision is V2.3, and PROFIBUS uses Revision 3 and 5 and higher.
Any mounting position is supported. Diagnostic, limit value and hardware interrupt functions are available, with green channel-status and red channel-diagnostic LEDs.
