| Datasheet | Download Datasheet |
The Amperite 12D2HADOD is a time delay relay with SPST-NO (1 form A) contacts, driven by a 12 V DC input.
It has a fixed delay of 2 h, set at the factory.
It is a Delay on Dropout timer.
12 volt power is applied to the relay at all times. When the ignition circuit of the vehicle is activated the relay contacts close. When the ignition circuit is turned off the timing cycle begins. At the end of the time delay the relay contacts open. Reset is accomplished by reactivating the ignition circuit of the vehicle.
