Carlo Gavazzi PUA01CB23500V Voltage Monitoring Relay

The Carlo Gavazzi PUA01CB23500V is a 1‑phase AC/DC voltage monitoring relay with overvoltage and AC overcurrent sensing and a single SPDT relay output, designed for quick integration in control panels. It uses a 115/230 V AC supply and comes in a 36 mm plug‑in housing for straightforward installation. The device supports a broad nominal range of 2–500 V AC/DC or 0.4–4 Vp AC (MI/MP), with monitored external voltages specified across 24–240 Vac/dc; 208–480 Vac; and 2–500 Vac/dc. Output characteristics include one relay with no adjustable time delay, enabling immediate signaling or interlock actions when voltage conditions exceed preset limits. This monitoring relay is suited for safeguarding equipment and signaling when the monitored voltage deviates from safe operating ranges, making it a practical choice for power supplies, drives, and control circuits that require fast, reliable voltage supervision.
