Voltage Monitoring Relays What it does Monitors supply voltage and provides a controlled signal or switching action when voltage moves outside preset limits. Protects connected equipment from damage due to undervoltage or overvoltage conditions. Delivers a clear, repeatable control output to drive relays, PLCs, or motor starters. Key benefits Reduces downtime and equipment wear by preventing operation under unsafe voltage conditions. Enables automatic protection and safe shutoff without constant supervision. Simple threshold adjustment and reliable, repeatable operation. Standout features Adjustable under and over voltage trip points to match system requirements. Hysteresis options to minimize nuisance trips and guarantee stable switching. Isolated input and output to protect control circuits and improve safety. Compact enclosure designed for easy integration into control panels and equipment racks. Robust construction and durable materials suitable for industrial environments. Function and performance Accurate voltage sensing with fast response to changes in supply. Reliable switching output compatible with standard control circuits and automation inputs. Consistent performance across a range of ambient conditions, with stable operation over time. Compatibility and mounting Designed to integrate with common control systems, PLCs, and motor protection schemes. Suitable for panel mounting in control cabinets and small electrical enclosures. Wiring designed for straightforward installation with minimized configuration effort. Size and material Compact form factor that fits in tight panel spaces without compromising visibility or accessibility. Durable enclosure suitable for industrial use, with insulated terminals and safe handling. Applications and use scenarios Industrial automation line protection: Monitors main supply voltage to a line and triggers shutdown of a motor starter if voltage drops below the safe range, helping prevent motor overheating and equipment damage. Conveyor and automation equipment protection: Keeps conveyors, robotic feeders, and drives from starting or continuing operation when voltage is outside acceptable limits, reducing wear and maintenance needs. Criticalload power supervision: Guards sensitive systems in data centers, telecom cabinets, or missioncritical cabinets by ensuring power feeds remain within specified voltage bounds, triggering alarms or isolation as needed.
