Why Choose the Carlo Gavazzi DBB51CM2410S True Delay-on-Release Timer?
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.
Key Advantages
- Capacitor-powered true delay-on-release operation.
- Precisely adjustable timing range from 1–10 s.
- Flexible 24 V DC or 24–240 V AC supply.
- Reliable 5 A SPDT changeover relay output.
- Automatic countdown begins when supply voltage is removed.
- Slim 17.5 mm housing conserves DIN-rail space.
Key Features
- Carlo Gavazzi DBB51 true delay-on-release timer series.
- Dedicated 1–10 s timing range.
- Front-mounted knob with an absolute time scale.
- SPDT relay output rated at 5 A at 250 V AC for resistive loads.
- Timing repeatability of ≤ 0.2%.
- Green power-supply LED and yellow relay-status LED.
- Automatic timing reset when supply power is reapplied.
- Compact DIN-rail housing with screw-terminal connections.
Compact True Off-Delay Control
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.
Typical Applications
- Short delayed machinery shutdown sequences.
- Fan, blower and pump run-on control.
- HVAC and refrigeration equipment.
- Packaging and material-handling machinery.
- Lighting and alarm control systems.
- Industrial control panels and OEM equipment.
