1. About the NI Direct Injector Driver System
The NI Direct Injector Driver System features an NI CompactRIO controller, NI 9751 Direct Injector (DI) driver
module(s), and a NI 9411 digital input module. The system can synchronize injector channels with production crank/
cam position sensors or research optical encoders. The system will also accept external digital fuel command
signals from a production engine controller. The included DI driver module(s) provide the power electronics
necessary to drive high-power solenoid or piezoelectric direct injectors.
The NI Direct Injector Driver System comes in four different models corresponding to different direct injector channel
configurations: the NI DIDS-2103 drives 3 solenoid injectors (or 2 piezoelectric injectors), the NI DIDS-2106 drives
6 solenoid injectors (or 4 piezoelectric injectors), the NI DIDS-2109 drives 9 solenoid injectors (or 6 piezoelectric
injectors), and the NI DIDS-2112 drives 12 solenoid injectors (or 8 piezoelectric injectors). Additionally, the NI
DIDS-2109 and DIDS-2112 feature a NI 9760 VR/Hall module capable of accepting variable reluctuance engine
position signals. The systems provide a digital input per injector channel for directly commanding each injector.
The system controller is delivered with a pre-installed, feature-rich application. The deployment version of the NI
Software Calibration Manager Toolkit (SCM) is included for interfacing with and calibrating the system.
The NI Direct Injector Driver System supports two optional C-series modules. The optional NI 9758 PFI driver
module can be used to drive port fuel injectors, proportional solenoid valves and relays. The optional NI 9201 analog
input module can be used for a variety of analog sensors. Common-rail fuel pressure control is an example feature
of the NI Direct Injector Driver System that utilizes these modules. Also, NI DIDS-2103 and DIDS-2106 customers
can optionally add a NI 9760 module for VR sensor support.
Throughout this manual, the model number NI 9751 and model name DI Driver module are used interchangeably.
Similarly, the model number NI 9758 and model name PFI Driver are used interchangeably.
