TWO PRODUCT TYPES: EUL (.2 TO 60V) AND EUH (10 TO 600V) PROVIDE SELECTABLE OVER OR UNDER VOLTAGE CONTROL. Control of AC / DC voltage without memory When the value of the controlled voltage, AC or DC, reaches the threshold Ue displayed on the front face, the output relay changes state at the end of a time delay T which can be set on the front face at between 0.1 and 3 s. 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. Control of AC / DC voltage with memory When the value of the controlled voltage, AC or DC, reaches the threshold Ue displayed on the front face, the output relay changes state at the end of a time delay T which can be set on the front face at between 0.1 and 3 s, and stays locked in this position.

*Important: For 24 VDC Input power models, the supply voltage and the measured voltage must be from separate sources. The “negative” poles of the auxiliary power and the measurement circuit are connected inside the unit.
