Working Voltage: DC 12V Delay Time: T=1.1RC Input Power Light: Yes Relay Actuation Light: Yes Application: 1)Connecting it with the vehicle equipment in case the vehicle equipment being damaged for the high current. 2)It can protect several equipment from damaging for working together. Features: 1)The relay will delay to close after connecting with the power supply. 2)The time of delay can be adjusted from 0-10s 3)It can control equipment AC below 220V/10A,power below 2000W. 4)With relay current protection function 5)Increase of the potentiometer leads to time delay increase. 6)Enlarging the capacitor leads to time delay increase.
