EUL/EUH AC/DC voltage control
Voltage control
■ Voltage monitoring
■ 2 relays to cover 6 ranges of measurement : 0.2 V to
600 V
■ Automatic recognition AC/DC
■ Frequency up to 500 Hz
General characteristics
Supply voltage Un 24 V, 120 V, 230 V, 50/60 Hz (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 40 500 Hz
Threshold Use Adjustment from 10 to 100 % of the measurement range
Hysteresis Adjustment from 5 to 50 % of the displayed threshold
Display accuracy ± 10 % of the full scale
Delay on energization T1 0.1 3 s ±10 %
Output relay 1 AgNi changeover, 8 A max
Temperature Use (°C) -20 ➞ +60
Storage temperature ( 0 C) -30 ➞ +7
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.
Once the voltage drops below 5 to 50 % of the threshold (hysteresis) , the output relay changes state
again instantly. Changing the hysteresis on the front face does not therefore modify the value of the
preset threshold.
