Why Choose the Carlo Gavazzi DBB01C724 True Delay-on-Release Timer?
The Carlo Gavazzi DBB01C724 is a capacitor-powered true delay-on-release timer relay designed to maintain a controlled output 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 the output remains energised before releasing at the end of the delay. Because its release delay is capacitor powered, the timer performs this function without requiring 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 SPDT relay output, the DBB01C724 is ideal for controlled shutdown and run-on applications. Its 22.5 mm DIN-rail housing enables straightforward installation inside industrial control panels.

True Delayed Release Without a Continuous Supply
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 DBB01C724 begins timing automatically following supply interruption and releases its output when the selected period expires. If power returns before the relay releases, the timing cycle resets and the relay remains energised, supporting reliable operation in automated shutdown and run-on circuits.
Typical Applications
- Delayed machinery shutdown sequences.
- Fan, blower and pump run-on control.
- Industrial automation and process equipment.
- Motor control centres and electrical panels.
- Packaging and production machinery.
- Lighting, alarms and ventilation systems.
