Why Choose the Carlo Gavazzi DUB01CB23500V Voltage Monitoring Relay?

The Carlo Gavazzi DUB01CB23500V is a compact and reliable single-phase AC/DC voltage monitoring relay designed to protect electrical systems by detecting overvoltage and undervoltage conditions. As part of the proven Carlo Gavazzi DUB01 monitoring relay series, it provides accurate voltage supervision for industrial automation, electrical control panels and machinery protection applications.

This monitoring relay continuously monitors an external voltage signal and switches its relay output when the measured voltage exceeds or falls below configured limits. Its selectable measuring ranges, adjustable voltage threshold, hysteresis control, latch function and compact DIN-rail housing make it suitable for reliable industrial voltage monitoring.

With a 2–500 V AC/DC monitoring range, a 115/230 V AC supply voltage and a SPDT relay output, the DUB01CB23500V is ideal for applications requiring dependable overvoltage and undervoltage protection in industrial control systems.
