The Carlo Gavazzi DBB01DM24 is a capacitor-powered true delay-on-release timer relay designed to maintain two changeover outputs for a controlled period after its 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 wide 24–240 V AC/DC supply and an 8 A DPDT relay output, the DBB01DM24 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.
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 DBB01DM24 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.

This timer keeps two changeover contacts energised for an adjustable period after the power supply is removed, making it suitable for controlled shutdown and run-on applications.
True delay on release means the timer uses internally stored energy to maintain its outputs during the delay period without requiring continuous external power.
The timer provides four selectable ranges covering adjustable delays from 0.1–600 s.
The DBB01DM24 operates from a wide 24–240 V AC/DC supply.
It has an 8 A DPDT relay output providing two changeover contacts for switching two circuits.
Carlo Gavazzi timer relays are widely used by control-panel builders, machine manufacturers and automation engineers for reliable timed switching in industrial equipment and building automation systems.
