Overview

The Carlo Gavazzi DUB02CT23 is a 1-phase True RMS over/under voltage monitoring relay (SKU: DUB02CT23). It measures AC/DC voltage from 19.2 to 275V and protects equipment by disconnecting power when voltage falls outside adjustable upper/lower limits. Housed in a 22.5x83.5x99.5mm DIN-rail mountable IP20 enclosure, it operates on 24/115/230Vac power and includes a 1 SPDT relay output rated 16A @ 240V AC. An adjustable 0.1-10 second drop-out delay prevents nuisance tripping. Ideal for safeguarding sensitive loads from damaging voltage fluctuations in industrial, commercial, or automation applications.
  • True RMS voltage monitoring for AC/DC from 19.2 to 275V
  • Adjustable over/under voltage setpoints with hysteresis control
  • 1 SPDT relay output rated 16A @ 240V AC, 16A @ 24V DC
  • Adjustable drop-out delay (0.1-10s) to prevent nuisance tripping
  • Compact DIN-rail mountable IP20 housing (22.5x83.5x99.5mm)

Frequently Asked Questions

What are the available AC voltage measuring ranges for this relay?

The relay can measure AC voltages in ranges of 24 VAC, 115 VAC, or 230 VAC.

What is the output relay type and its contact ratings?

The output is a 8 A SPDT relay. For resistive loads (AC 1), it is rated for 8 A @ 250 VAC.

What is the operating temperature range for the DUB02 and PUB02 relays?

These relays can operate in a temperature range of -20 to 60°C with a relative humidity below 95%.

How is the power supply voltage for the relay selected?

The power supply voltage (24, 115, or 230 VAC) is selectable by DIP-switch.

What is the function of the latch and inhibit features?

The latch function keeps the relay energized after an alarm condition, while the inhibit function prevents relay operation when not desired.

What are the dimensions of the DUB02 and PUB02 housings?

The DUB02 has a 22.5 mm housing, and the PUB02 has a 36 mm plug-in module housing.

What is the adjustable delay range for alarms or recovery?

The delay on alarm or recovery can be adjusted from 0.1 to 30 seconds.

What is the Power ON delay time for the relay?

The Power ON delay is selectable by DIP-switch and can be either 1 second or 6 seconds, each with a tolerance of ± 0.5 seconds.
