Carlo Gavazzi DBB51CM2410S capacitor-powered true delay-on-release timer relay with a 1–10-second adjustable range, 24 V DC or 24–240 V AC supply and 5 A SPDT output.
£79.76
The Carlo Gavazzi DBB51CM2410S is a compact, capacitor-powered true delay-on-release timer relay designed to maintain its changeover output for a preset period after the power supply is removed. As part of the Carlo Gavazzi DBB51 timer series, it provides reliable short-duration timed switching for industrial machinery, automation equipment and electrical control systems.
When power is applied, the relay energises automatically. Removing the supply starts the countdown period, during which the output remains energised before releasing at the end of the selected delay. If power returns before the relay releases, the timing cycle resets and the output remains energised.
With an adjustable timing range of 1–10 s, a 24 V DC or 24–240 V AC supply and a 5 A SPDT relay output, the DBB51CM2410S is ideal for controlled shutdown and brief run-on applications. Its slim 17.5 mm DIN-rail housing conserves valuable space inside electrical 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 allows a controlled delay to continue without a separate trigger input or continuous external power during the countdown.
The DBB51CM2410S provides straightforward adjustment over a 1–10 s range using its front-mounted dial. Its status LEDs, compact housing and wide AC supply compatibility make it easy to integrate into machinery and control-panel applications.

This timer keeps its changeover output energised for an adjustable period after supply power is removed, making it suitable for controlled shutdown and brief equipment run-on applications.
The timer provides an adjustable delay range of 1–10 s.
The DBB51CM2410S operates from either a 24 V DC supply or a 24–240 V AC supply.
It has one SPDT changeover relay output rated for resistive loads up to 5 A at 250 V AC.
The timer is designed for DIN-rail mounting inside machinery cabinets, HVAC control systems and industrial electrical panels.
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.
