Carlo Gavazzi DUB01CD48500V Voltage Level Relay

Carlo Gavazzi DUB01CD48500V is a 1-phase AC/DC voltage monitoring relay with a single SPDT (form C) output housed in a compact 22.5 mm DIN-rail module. It runs from a 24–48 V AC/DC supply and monitors an external voltage in the 2–500 VAC/DC range, offering selectable modes for overvoltage, undervoltage, or both. The device provides one relay contact for signaling or interlocking in control circuits and incorporates a 30-second delay on alarm to prevent nuisance triggering from transients. This voltage level relay is designed for panel installations in industrial environments, enabling reliable voltage supervision in single-phase power systems and easy integration with PLCs or other control logic through its normally open/normally closed relay configuration. Its DIN-rail mounting and clear, voltage-based trip behavior make it a practical choice for safeguarding equipment and ensuring appropriate responses when supply conditions exceed or fall below set thresholds.
