This voltage monitoring relay monitors single-phase supplies of 20-80 VAC/DC (50-60 Hz) for exceeding or falling below an adjustable threshold in window mode. It features a relay changeover contact rated for up to 5 A. The lower and upper limits, as well as a shutdown delay, are adjustable. Settings are made via control elements on the front, which can be protected against changes under a transparent cover. Two LEDs indicate the status. The device is powered from the measurement voltage (rated voltage 24-48 VAC/DC, 50-60 Hz). The width of the device is 17.5 mm, and it is mounted on a DIN rail.
