This 12 VDC Relay Driver is especially developed for Automotive use, allowing microcontroller to switch on common automotive relays with 12 VDC coils.
Command Signal of low current at low voltage (Typically 1 milliAmpere @ 3 V to 5 V DC) into the Relay Driver electronically switches ON a Higher current Load (up to 1A) at typical automotive system voltage (10 VDC to 14.4 VDC).
In constant ON applications it can carry up to 1 Ampere load, while in pulsed applications up to 2 Amperes may be switched ON momentarily.
The 12 VDC Relay Driver can be used to switch on automotive type relays, which can then control lights, fans, motors and other devices ON/OFF while keeping them isolated from the microcontroller.
The LED located on the PCB is ON when the Output Pin (To Relay 85-) is connected to Ground (GND).
Control Input can be connected directly to any output pin of PARALLAX PROPELLER microcontroller without need for any resistors.
