Multifunction Measuring Relay, for Modbus, UG 9400

Type:  Monitoring Hardware
Description:  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.
Connectivity:  Modbus RTU
Features:  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
Specifications:  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
