Time Delay on Release Relay - 12V DC, 30 Amp
The 12 volt change over relay is an adjustable relay that can maintain a power supply for as short as 2 seconds, or for as long as 3 minutes after power is switched off. Essentially, the solid state timing circuit with variable resistor within the relay allows for this to happen. In order to adjust the timing, the easy access top waterproof adjusting cover must be removed, and the adjustable potentiometer must be turned. A common use for this type of change over relay is to power a vehicle's dome lights, which allows drivers and passengers additional time to exit the vehicle before the courtesy lights go dark. This is just one example of many applications for timer relays. This particular change over time delay relay is normally closed/normally open and fits a standard 5 terminal harness configuration.
- Solid state timing circuit with variable resistor allows for an adjustable time from 2 seconds to 3 minutes (must remove cover to reach adjustment screw on base).
- Fits standard relay 5 terminal harness configurations.
- Built in diode to stop timer feedback issues.
- SPDT Change Over NC/NO (form C).
- Rated up to 20/30 Amp, 12V DC.
- Voltage range: 8.2 ~ 14.8V DC.
- Operating temperature range: -40°C to 80°C (-40°F to 176°F).

Hella Time Delay on Release Relay - 12V DC
A time delay relay may be used for event sequencing, instrumentation control, in an alarm circuit or watchdog circuit. Sometimes two time-delay relays are used in conjunction with each other to provide a pulsing signal. These two time delay relays can be combined to form what is commonly known as a repeat cycle timer. Delay on Release relay can be used to power a vehicle's dome lights, which allows passengers and drivers additional time to exit the vehicle. Delay on Operate relay can be used to protect sensitive, critical equipment during system power-up by providing a brief time delay during start-up until the system is fully energized. These relays offer easy access to timing adjustments without having to remove a cover or the relay from the circuit. 12V. Time Delay Range: 0-900 seconds (0-15 minutes). Includes mounting bracket.
