Why Choose the Carlo Gavazzi DUB72D724EX Voltage Monitoring Relay?

The Carlo Gavazzi DUB72D724EX is a robust DC double undervoltage monitoring relay designed to monitor 24 V DC power systems and provide reliable protection against brownout and low-voltage conditions in industrial and hazardous environments. As part of the advanced Carlo Gavazzi DUB72 monitoring relay series, it is designed for demanding applications including industrial automation, energy systems and potentially explosive environments.

This monitoring relay provides two independently adjustable undervoltage thresholds with two separate relay outputs, allowing one output to be used as a pre-alarm and the second as a main alarm or load disconnect function. Its compact DIN-rail housing and tropicalised PCB construction provide reliable operation in industrial cabinets and harsh environmental conditions.

With a monitored voltage range of 15–30 V DC and dedicated relay outputs rated for different load requirements, the Carlo Gavazzi DUB72D724EX is ideal for monitoring battery systems, DC power supplies and critical 24 V control circuits where reliable undervoltage protection is required.
