£115.57
The Carlo Gavazzi DUB71CB2310V is a precise and reliable single-phase AC/DC overvoltage and undervoltage monitoring relay designed to protect electrical systems by continuously monitoring external voltage signals. As part of the advanced Carlo Gavazzi DUB71 monitoring relay series, it provides accurate voltage supervision for industrial automation, electrical control panels and machinery protection applications.
This monitoring relay uses true RMS measurement technology and selectable measuring ranges to provide accurate voltage monitoring across a wide variety of applications. Adjustable hysteresis, adjustable delay functions, programmable latching and inhibit functions provide flexible configuration for demanding industrial environments.
With a 0.1–10 V AC/DC monitoring range, a 115/230 V AC supply voltage and a SPDT relay output, the DUB71CB2310V is ideal for low-voltage signal monitoring applications requiring dependable overvoltage and undervoltage protection.
Voltage monitoring relays such as the Carlo Gavazzi DUB71CB2310V provide continuous supervision of electrical signals to help protect sensitive equipment, machinery and automation systems. By detecting abnormal voltage conditions, they can trigger alarms or switching actions before faults affect system operation.
The DUB71 series is designed for industrial engineers and panel builders requiring accurate and flexible voltage monitoring solutions. Its true RMS measurement, adjustable parameters and relay output allow straightforward integration into modern electrical installations.
