Fuel Injector Driver Module
(Fully Assembled Module)

Product Use

This 12 VDC Fuel Injector Driver Module is especially developed for Automotive use.

It is also used in OKA modular Fuel Injection System for Small Engines.

The 12 VDC Fuel Injector Driver Module is major component of the Electronic Fuel Injection System (EFI). It controls the opening and closing of solenoid type Fuel Injector to deliver the required volume of fuel.

When "Injector ON" control signal (+3 VDC to +5 VDC) is applied to the 12 VDC Fuel Injector Driver Module the Output is automatically turned ON through a high current Darlington Transistor, and then goes OFF when the signal is switched to Ground (0 VDC).

The 12 VDC Fuel Injector Driver Module is used to provide power signal Switched Ground (0 VDC), which is used  to switch ON the Fuel Injector for the duration of the control signal that is provided by the EFI Controller.

There is Status Indicator LED located on the Module:

Red LED is ON when the Module is operational.

The 12 VDC Fuel Injector Driver Module contains internal automatic power logic which limits the current flow after the initial Injector Opening. This not only reduces the power consumption but also allows for control of both HIGH and LOW resistance Injectors.
