In general, our CompactRIO DI Driver Module Kits are intended to be used within a full authority engine control system where the CompactRIO controller or PXI controller are executing full authority engine control algorithms. However, some customers may already have a full authority gasoline engine controller and need only direct injector drivers commanded by their pre-existing gasoline port fuel injector outputs or other engine synchronous TTL outputs. We now have a family of driver systems that enable this configuration.

We have 3 channel, 6 channel, 9 channel, and 12 channel stand-alone DI driver systems available.  Each system includes the following:

3 Channel Stand Alone DI Driver System

1 cRIO-9012 RT Controller

1 cRIO-9111 4-Slot FPGA Chassis

1 Drivven DI Driver Module

1 cRIO-9411 Digital Input Module

6 Channel Stand Alone DI Driver System

1 cRIO-9012 RT Controller

1 cRIO-9111 4-Slot FPGA Chassis

2 Drivven DI Driver Modules

1 cRIO-9411 Digital Input Module

9 Channel Stand Alone DI Driver System

1 cRIO-9012 RT Controller

1 cRIO-9112 8-Slot FPGA Chassis

3 Drivven DI Driver Modules

2 cRIO-9411 Digital Input Modules

12 Channel Stand Alone DI Driver System

1 cRIO-9012 RT Controller

1 cRIO-9112 8-Slot FPGA Chassis

4 Drivven DI Driver Modules

2 cRIO-9411 Digital Input Modules

Each system is delivered with an installed executable application which allows an external digital fuel control signal to be input to the digital input module and routed directly to the DI Driver modules.  The system provides a user interface which allows the user to calibrate the injector current profile and save the settings.  The calibration settings are stored on the cRIO controller and used immediately upon system boot.  The user interface is accessed by connecting a computer directly to the CompactRIO controller via an Ethernet cable or by putting the system on a network.  LabVIEW development tools are NOT required, but the free LabVIEW Run-time Engine IS required, as well as Drivven's free version of CalVIEW used to run the user interface.  The user interface is not required for normal operation.  The system is ready to run after the 20 second power-on boot time.   No other products from National Instruments or Drivven are required for this system to operate.  Just provide an external power source from 9V to 30V, connect the injectors, and connect the external controller digital commands.  If you send us your injector ahead of time, we will calibrate the current profile for you so that you can run right out of the box, for no additional charge.

Due to the specialized software for these configurations, it is not possible for customers to build these systems by piecing together the above listed components.  These are sold as complete systems, without the need for LabVIEW development tools.
