1. About the NI Expandable Direct Injector Driver System
The NI Expandable Direct Injector Driver System features an NI cRIO-9082 controller, NI 9751 Direct Injector (DI)
driver module(s), and NI 9411 digital input module(s). The system can synchronize injector channels with production
crank/cam position sensors or 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 Expandable Direct Injector Driver System comes in four different base models corresponding to different
direct injector channel configurations: the NI EDIDS-2403 drives 3 solenoid injectors (or 2 piezoelectric injectors),
the NI EDIDS-2406 drives 6 solenoid injectors (or 4 piezoelectric injectors), the NI EDIDS-2409 drives 9 solenoid
injectors (or 6 piezoelectric injectors), and the NI EDIDS-2412 drives 12 solenoid injectors (or 8 piezoelectric
injectors). 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 Expandable Direct Injector Driver System supports optional C-series modules in slots 7 & 8 of the
cRIO-9082. The optional NI 9220 analog input module (slot 7) can be used for a variety of analog sensors. The
optional NI 9862 XNET CAN module (slot 8) can be used to send and receive parameter values within the system
to/from other CAN communication devices. The cRIO-9082 controller may be expanded with a NI-9155 MXIe
Expansion Chassis for additional optional modules with designated slots. Examples of optional modules designated
to expansion slots are NI-9758 Port Fuel Injector Driver Module, NI-9754 Engine Synchronous TTL Output Module,
NI-9757 Bosch LSU 4.2 and 4.9 O2 Sensor Module, NI-9759 Throttle Driver Module and the NI 9760 VR/Hall Sensor
Module.
Throughout this manual, the module model numbers NI 9XXX (ex. NI 9751) and module model names (ex. DI Driver
module) are used interchangeably. Also, the NI Expandable Direct Injector Driver System will be referred to as the
NI Direct Injector Driver System.
