Carlo Gavazzi DUB02CT23 single phase AC/DC voltage monitoring relay designed for overvoltage and undervoltage detection in industrial control systems.
£119.76
The Carlo Gavazzi DUB02CT23 is a precise and reliable single-phase AC voltage monitoring relay designed to protect electrical systems by detecting overvoltage and undervoltage conditions. As part of the advanced Carlo Gavazzi DUB02 monitoring relay series, it provides dependable voltage supervision for industrial automation, electrical control panels and machinery protection applications.
This monitoring relay continuously measures its own supply voltage and activates its relay output when the voltage moves outside the configured window limits. With true RMS measurement, programmable latching and inhibit functions, LED status indication and a compact DIN-rail housing, the DUB02CT23 provides flexible protection for industrial electrical systems.
With a 24–240 V AC/DC monitoring range, a self-powered design and a SPDT relay output, the DUB02CT23 is ideal for applications requiring reliable overvoltage and undervoltage monitoring in industrial control systems.
Voltage monitoring relays such as the Carlo Gavazzi DUB02CT23 provide continuous supervision of electrical supplies to help protect machinery, automation equipment and control systems. By detecting abnormal voltage conditions, they can trigger alarms or switching actions before faults affect operation.
The DUB02 series is designed for industrial engineers and panel builders requiring accurate and flexible voltage monitoring solutions. Its true RMS measurement, programmable functions and relay output allow straightforward integration into modern electrical installations.
