Why Choose the Carlo Gavazzi DBB01D724 True Delay-on-Release Timer?

The Carlo Gavazzi DBB01D724 is a capacitor-powered true delay-on-release timer relay designed to maintain two changeover outputs for a controlled period after its DC power supply is removed. As part of the Carlo Gavazzi DBB01 timer series, it provides dependable timed switching for industrial machinery, automation equipment and electrical control systems.

When power is applied, the relay energises automatically. Removing the supply starts the selected timing period, during which both output contacts remain energised before releasing at the end of the delay. Because its release delay is capacitor powered, the timer performs this function without a separate trigger input or continued external supply during timing.

With four selectable timing ranges covering 0.1–600 s, a 12–24 V DC supply and an 8 A DPDT relay output, the DBB01D724 is ideal for controlled shutdown and run-on applications requiring two changeover contacts. Its 22.5 mm DIN-rail housing enables straightforward installation inside industrial control panels.

Key Advantages

  • Capacitor-powered true delay-on-release operation.
  • Wide adjustable timing range from 0.1–600 s.
  • Flexible 12–24 V DC operating supply.
  • Versatile 8 A DPDT relay output with two changeover contacts.
  • Four timing ranges selectable using internal DIP switches.
  • Automatic timing start when the power supply is removed.

Key Features

  • Carlo Gavazzi DBB01 true delay-on-release timer series.
  • Four selectable ranges covering 0.1–600 s.
  • 12–24 V DC supply range.
  • DPDT relay output rated at 8 A at 250 V AC for resistive loads.
  • Timing repeatability of ≤ 0.2%.
  • Knob-adjustable delay setting with DIP-switch range selection.
  • Green LED indication for power-supply status.
  • DIN-rail housing with screw-terminal connections.

True Delayed Release with Two Changeover Contacts

A true delay-on-release timer uses stored internal energy to keep its relay energised for a preset period after supply power is removed. This makes it suitable for applications where a controlled delay must continue even though the initiating power source is no longer present.

The DBB01D724 begins timing automatically following supply interruption and releases both changeover contacts when the selected period expires. If power returns before the relay releases, the timing cycle resets and the relay remains energised, supporting reliable multi-circuit control in automated shutdown and run-on systems.

Typical Applications

  • Delayed machinery shutdown sequences.
  • Fan, blower and pump run-on control.
  • Simultaneous switching of two control circuits.
  • Motor control centres and electrical panels.
  • Packaging and production machinery.
  • Lighting, alarms and ventilation systems.

Frequently Asked Questions

What is the Carlo Gavazzi DBB01D724 used for?

This timer keeps two changeover contacts energised for an adjustable period after the DC power supply is removed, making it suitable for controlled shutdown and run-on applications.

What does true delay on release mean?

True delay on release means the timer uses internally stored energy to maintain its outputs during the delay period without requiring continuous external power.

What timing range does the DBB01D724 provide?

The timer provides four selectable ranges covering adjustable delays from 0.1–600 s.

What supply voltage does the timer require?

The DBB01D724 operates from a 12–24 V DC supply.

What type of output does the DBB01D724 have?

It has an 8 A DPDT relay output providing two changeover contacts for switching two circuits.
