The Time Delay Relay – DODO-D is a field-adjustable relay designed to keep an electrical load energized for a predetermined time interval after the controlling signal is removed. This compact relay is specifically engineered for use in fire apparatus, ambulances, rescue vehicles, command vehicles, and other specialty vehicle electrical systems. It provides dependable delayed shutoff control for interior lighting and other 12 VDC electrical accessories, making it an essential component in applications where precise timing of electrical load activation and deactivation is required.
When a +12 VDC control signal is applied, the relay closes immediately and energizes the connected load. Once the control signal is removed, the relay remains energized for the selected delay interval before automatically returning to its normal state. The field-adjustable delay can be set from 4 to 15 seconds, with a factory set point of 10 seconds. Both normally open and normally closed 30-amp relay contacts are provided, allowing for flexible circuit integration in various vehicle electrical systems. The relay requires three input connections: +12 VDC power, ground, and a +12 VDC control signal, ensuring reliable operation in demanding environments.
Designed with heavy-duty 30-amp relay contacts, the DODO-D is built to handle the rigorous demands of vehicle electrical systems. Its compact design simplifies installation while maintaining high reliability and performance. The relay's adjustable time delay feature allows for precise control over when electrical loads are turned off, which is critical in applications such as interior lighting where power should remain on until a specific moment after the initial signal is removed. This makes the DODO-D an ideal choice for emergency response vehicles where timing and safety are paramount.
