Voltage Monitoring Relays Purpose A compact relay module that monitors supply voltage and energizes or deenergizes its output when the voltage moves outside preset limits. Benefits Protects equipment from undervoltage and overvoltage conditions Reduces downtime caused by voltage faults Supports safe restart sequences Easy integration with existing control circuits Key attributes Adjustable voltage thresholds with clear hysteresis Fast response to voltage excursions Galvanic isolation between sensing and output Compact enclosure suitable for panel mounting Durable construction for industrial environments Function and performance Monitors voltage levels and provides a reliable relay output Status indication via an LED Low power consumption for continuous operation Designed for consistent performance in varying electrical conditions Compatibility and mounting Integrates with standard control circuits and control cabinets Compatible with common control voltages Small form factor for easy installation in control panels Physical characteristics Compact size with a robust enclosure Material chosen for industrial reliability and longevity Use scenarios Protect motor starters and contactors in conveyors by tripping on undervoltage Shield data center equipment from voltage sags to prevent unexpected reboots Manage building automation circuits for lighting and HVAC to avoid damage from voltage excursions Setup and maintenance Thresholds adjusted with a small screwdriver LED provides immediate status feedback Optional test function to verify operation without load
