Introduction
The National Instruments 9758 Port Fuel Injector (PFI) Driver Module includes a CompactRIO
(cRIO) module for driving low and high impedance Port Fuel Injectors (PFI) and general
purpose automotive solenoid valves and actuators. The NI 9758 includes a LabVIEW FPGA VI
for controlling each driver channel. Each PFI channel is individually controlled for timing and
duration. Each general purpose low-side solenoid driver is PWM controlled, capable of 0% to
100% duty cycle operation.
Features:
• 4-channel low or high impedance PFI driver
–
Two phase current control
– Turnable current level and duration for each phase
– Optional recirculation at end of pulse
– Open and short circuit detection and reporting with short circuit disable
• 4-channel general purpose low-side solenoid driver
–
1.5 A continuous duty
– PWM controlled
•
0% to 100% duty cycle operation
• 2 Hz to 10 kHz frequency operation
• 500 ns resolution
– Open and short circuit detection and reporting with short circuit disable
• External power supply of 7 V to 32 V
