23/06/2014 www.crouzet.com EUL/EUH AC/DC voltage control EUH Part number 84872031 Voltage monitoring 2 relays to cover 6 ranges of measurement: 0.2V to 600V Automatic recognition AC/DC Frequency up to 500Hz Part numbers Measurement range Supply voltage Type EUH 15600V 24 V AC 84 872 031 Specifications Supply voltage Un 24 V, 120 V, 230 V, 50/60Hz (galvanic isolation via transformer) 24 V (no galvanic isolation). In this case, the product power supply and measuring circuit power supply must be electrically isolated. Operating range 0,85 1,15 Un Maximum power consumption 3 VA / 1 W Frequency of measured signal 40 500Hz Threshold Ue Adjustment from 10 to 100% of the measurement range Hysteresis Adjustment from 5 to 50% of the displayed threshold Display precision 10% of the full scale Delay on thresold crossing Tt 0,1 3 s 10% Output relay 1 AgNi changeover, 8 A max Temperature Use (C) -20+60 0 -30+70 Storage temperature ( C) Inputs E1-M E2-M E3-M Sensitivity E1-M: 15 to 150V E2-M: 30 to 300V E3-M: 60 to 600V Input resistance E1-M: 100k E2-M: 300k E3-M: 600k Principles When the value of the controlled voltage, AC or DC, reaches the treshold Ue displayed on the front face, the output relay changes state at the end of a time delay T1, which can be set on the front Unless otherwise specified, the characteristics given are applicable to all or part of the product range selected23/06/2014 www.crouzet.com face at between 0.1 and 3s. Once the voltage drops below 5 to 50% of the treshold (hysteresis), the output relay changes state again instantly. Changing the hysteresis onthe front face does not therefore modify the value of the preset treshold. o N Legend Treshold Ue Hysteresis UPPER function UNDER function Unit power-up Controlled voltage *** TRADUCTION MANQUANTE *** Principles When the value of the controlled voltage, AC or DC, reaches the treshold Ue displayed on the front face, the output relay changes state at the end of a time delay T1, which can be set on the front face at between 0.1 and 3s and remains latched in this position. o N Legend Treshold Ue Hysteresis UPPER function UNDER function Unit power-up Controlled voltage Dimensions (mm) EUL / EUH Unless otherwise specified, the characteristics given are applicable to all or part of the product range selected
