Voltage Monitor Relays

Voltage Monitor Relays monitor either AC single phase (50-60Hz) or DC voltages to protect equipment against voltage fault conditions. No separate supply (input) voltage is required on any Macromatic Voltage Monitor Relay since each unit is powered by monitored voltage. Versions are available in either a compact plug-in case utilizing an 8 pin octal socket or a 17.5mm DIN Rail mounted case.
