Time Delay Relay – DODO-A

The Time Delay Relay – DODO-A 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 that need to remain powered temporarily after the control signal is turned off. The DODO-A is a reliable solution for maintaining power in critical systems where a controlled delay is necessary before the load is disconnected.

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 1.5 to 6 minutes, with a factory set point of 3 minutes. Both normally open and normally closed 30-amp relay contacts are provided for flexible circuit integration. The relay requires three input connections: +12 VDC power, ground, and a +12 VDC control signal. This makes it easy to integrate into existing vehicle electrical systems without requiring major modifications.

The DODO-A is designed with heavy-duty 30-amp relay contacts that provide dependable load control in demanding environments. Its compact design simplifies installation in vehicle electrical systems, making it an ideal choice for fire apparatus, ambulances, rescue vehicles, and other specialty vehicles where space is limited but performance is critical. The relay's ability to maintain power for a set period after the control signal is removed ensures that essential systems remain operational until they are no longer needed. This feature is particularly important in emergency response vehicles where reliable electrical systems are vital to safety and mission success.
