Time Delay Relay – DODO-C

The Time Delay Relay – DODO-C 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 require an extended operating period after the control signal is turned off. The DODO-C is a reliable solution for maintaining power in critical systems while ensuring safe and controlled shutdowns.

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 allows for precise control, with the ability to set the time from 12 to 60 minutes. The factory default setting is 30 minutes, making it suitable for a wide range of applications. Both normally open and normally closed 30-amp relay contacts are provided, offering flexibility in circuit integration and ensuring reliable load management.

The DODO-C requires three input connections: +12 VDC power, ground, and a +12 VDC control signal. This straightforward setup makes it easy to integrate into existing vehicle electrical systems. The relay's compact design simplifies installation while maintaining high performance and durability. Its heavy-duty 30-amp contacts are built to handle the demands of demanding environments, ensuring long-term reliability. Whether used for lighting, equipment, or accessories that need to remain powered after shutdown, the DODO-C offers a dependable and efficient solution.
