Why Choose the Carlo Gavazzi DBA52CM24 Delay-on-Release Timer?
The Carlo Gavazzi DBA52CM24 is a compact and reliable delay-on-release timer relay designed for timed switching in industrial automation, machinery and electrical control systems. As part of the Carlo Gavazzi DBA52 timer series, it combines flexible delay adjustment with a multi-voltage power supply and an SPDT changeover relay output.
The output relay operates when the external trigger contact closes, and the selected delay period begins when that contact opens. The relay remains energised until the delay expires, enabling controlled run-on periods, shutdown sequences and delayed disconnection functions.
With seven selectable timing ranges covering 0.1 s to 100 h, a 24 V DC or 24–240 V AC supply and a 5 A SPDT relay output, the DBA52CM24 provides versatile control in a space-saving format. Its slim 17.5 mm DIN-rail housing is ideal for installation in densely populated control panels.
Key Advantages
- Versatile delay-on-release function for automated control sequences.
- Wide adjustable timing range from 0.1 s to 100 h.
- Combined 24 V DC and 24–240 V AC supply input.
- Reliable 5 A SPDT changeover relay output.
- Simple knob selection of the timing range and delay setting.
- Slim 17.5 mm housing conserves DIN-rail space.
Key Features
- Carlo Gavazzi DBA52 delay-on-release timer series.
- Seven selectable ranges covering 0.1 s to 100 h.
- 24 V DC and 24–240 V AC multi-voltage operation.
- 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.
- Manual timing reset through the trigger input.
- Compact DIN-rail housing with screw-terminal connections.
Reliable Timed Control for Automation Systems
Delay-on-release timers maintain an energised relay output for a preset period after the control trigger is removed. This controlled delay is useful when machinery, ventilation equipment or other electrical loads must continue operating briefly after a switch, sensor or controller changes state.
The DBA52CM24 allows its delay to be configured using front-mounted controls, while green and yellow LEDs provide clear indication of supply, timing and relay status. Its wide supply range and changeover output simplify integration into new equipment and existing control panels.
Typical Applications
- Delayed shutdown and equipment run-on circuits.
- Industrial machinery and process control systems.
- Motor control centres and electrical control panels.
- Packaging and production machinery.
- HVAC fans, pumps and ventilation equipment.
- Lighting, alarms and automated sequencing systems.
