The Carlo Gavazzi PUB01CB23500V is a compact and reliable single-phase AC/DC voltage monitoring relay designed for overvoltage and undervoltage monitoring in industrial automation and electrical protection systems. As part of the Carlo Gavazzi PUB01 monitoring relay series, it provides accurate true RMS voltage supervision with adjustable parameters and a dependable relay output for control and protection applications.
This monitoring relay continuously supervises external voltage levels and switches its relay output when configured limits are exceeded. The PUB01CB23500V includes adjustable monitoring settings, hysteresis and delay functions, providing flexible operation for demanding industrial environments where reliable voltage protection is required.
With a 115/230 V AC supply voltage, a selectable 2–500 V AC/DC monitoring range and a SPDT relay output, the PUB01CB23500V is suitable for industrial machinery, automation systems and electrical monitoring applications requiring dependable voltage supervision.
Voltage monitoring relays such as the Carlo Gavazzi PUB01CB23500V continuously supervise electrical voltage conditions and provide a switching output when user-defined limits are exceeded. This enables control systems to trigger alarms, disconnect equipment or initiate protective actions during abnormal voltage conditions.
The PUB01 series is designed for industrial automation engineers and electrical installers requiring accurate voltage monitoring with configurable operating parameters. Its compact plug-in format, relay output and adjustable functions allow straightforward integration into control panels and protection systems.
