Voltage Monitor Relays

Voltage sensing 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.

Plug-in: Used with 8-pin octal sockets. Allows for easy replacement without having to remove any control wiring. Macromatic sockets can either be mounted on 35mm DIN track or to the panel with two screws. All Macromatic plug-in time delay relays are UL Listed for use in both United States and Canada (cULus) when used with the appropriate Macromatic socket as well as Component Recognized (cURus) using any recognized socket. 

17.5mm Modular: Narrow compact design is ideal for saving space in control panels. These products are designed for easy mounting to 35mm DIN track. All Macromatic 17.5mm relays are UL Listed for use in the United States and Canada (cULus).
