Voltage Monitoring Relays

Voltage monitoring relays sense and evaluate AC single-phase (50 to 60 Hz) or DC voltages to protect equipment from fault conditions.

• Over/under voltage relays with fixed or adjustable time-delay drop-out will protect equipment from over- or under-voltage conditions.
• Voltage band relays protect equipment that is required to operate within an upper and lower voltage limit. The relay is energized and will remain that way as long as the monitored voltage remains within the adjustable range.

Features

• Monitors AC single-phase (from 90 to 600 VAC) and DC voltages (from 9 to 138 VDC)
• True RMS voltage measurement supports non-sinusoidal waveforms and ensures more accurate sensing
• All relays offer 10A contact rating
• Wide range of user adjustable pick-up voltages
• 8-pin socket mount (sold separately)
• LED indicates output relay status
• Select models support an adjustable drop-out delay (0.1 to 10 seconds)
• 1-year warranty
