Datasheet

HUL and HUH control relays are designed to control AC or DC voltages.
They automatically recognise the shape of the DC or AC signal (50 or 60 Hz).
The operating mode is set by the user.
A switch is used to select under or overvoltage modes, with or without latching.
The switch position, and hence the operating mode, is read by the product on energisation.
If the switch is set to a non-conforming position, the product goes into fault mode, the output relay stays open, and the LEDs flash to signal the position error.
If the switch position changes while the unit is operating, all the LEDs flash but the product continues to work normally with the function selected on energisation prior to the change of position.
The LEDs return to their normal state if the switch is reset to its initial position defined before the last energisation.
The under or overvoltage threshold value is set by a graduated potentiometer as a percentage of the U scale to be monitored.
The hysteresis is set by a graduated potentiometer from 5 to 50% of the preset threshold. The hysteresis value cannot be higher than the extremes of the measurement range.
