Multifunction monitoring relay VARIMETER PRO | UG 9400

under-voltageover-voltageover-current

The multifunctional measuring relay UG 9400 of the VARIMETER PRO series allows easy parameter setting, monitoring and diagnosis via a Modbus RTU interface. The measuring relay simultaneously monitors up to 9 different measured variables such as voltage, voltage asymmetry, current, cos phi, active, apparent and reactive power as well as frequency and phase sequence.The measurement in three-phase and single-phase networks is very easy and without much wiring effort. Features • Multifunctional measuring relay acc. to IEC/EN 60255-1 • With galvanic separated Modbus RTU interface • Voltage monitoring (1- or 3-phase) • Current monitoring • Frequency monitoring • Power factor cos phi • Phase sequence, phase failure • Voltage / angular asymmetry • Active, reactive and apparent power • Start up time delay, response delay • Adjustable hysteresis 0.2 ... 50 % of the response value • Error memory • 2 changeover contacts • Relay function energized / de- energized on trip parameterizable • Width 22.5 mm Advantages / Customer benefit • Simple parameterization, monitoring and diagnosis • Compact design • Simultaneous monitoring of up to 9 measured variables • Large measuring range 3 AC 24 ... 690 V • Min-, Max-value or window monitoring • Auxiliary voltage ranges AC/DC 24 ... 230 V or AC 24 ... 400 V • Early detection of irregularities • Increases plant availability and productivity • Differentiated error messages • Space and cost saving • Reduced wiring • Lower investment, operating and maintenance costs
