Time Delay on Release Relay - 12V DC, 30 Amp
Adjustable 12V Timer Relay for Extended Power Supply
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.
