National Instruments NI 9754 Powertrain Controls Engine Synchronous

Introduction

The National Instruments 9754 Engine-Synchronous TTL (ESTTL) Output Module provides eight channels of high-speed digital output that can be used for engine synchronous signaling and control of external drive circuits.

Features

• Sends commands to external custom driver circuits or smart actuators with built-in driver circuits
• 200 ns output resolution
• 8-channel TTL output
• LabVIEW FPGA support for high-speed engine-synchronous, multi-pulse fuel or spark control

Powering the Module

The NI 9754 requires power from the CompactRIO backplane male high-density D-SUB 15-pin (HD15) connector, which mates with the female HD15 connector on the NI 9754. This power source provides a regulated 5 V and ground to various digital logic functions within the NI 9754. The CompactRIO 5 V source is active whenever the CompactRIO or R Series Expansion Chassis is properly powered. You can power the NI 9754 only at the HD15 connector by plugging it into a CompactRIO or R Series Expansion Chassis.

Platform Compatibility

NI Powertrain Control modules require a hardware support system to function. You cannot use the modules independently or interface with third-party devices at the backplane HD15 connector. NI Powertrain Control modules are compatible with the following National Instruments platforms:

• CompactRIO, which consists of a CompactRIO controller, chassis, or integrated controller/chassis.
• NI PXI, which consists of any NI PXI chassis, NI PXI RT controller, and NI PXI-78xxR R Series FPGA card. The NI Powertrain Control modules are inserted into an NI R Series expansion chassis. Connect an NI R Series expansion chassis to the NI PXI FPGA card using a SHC68-68-RDIO cable.

Note NI Powertrain Control modules are not compatible with the National Instruments CompactDAQ chassis.

You can use NI Powertrain Control modules with NI cRIO-911x, NI cRIO-907x, and NI R Series Expansion systems under the following conditions:

• Leave one empty chassis slot between NI Powertrain Control modules and other NI modules.
• Maintain an ambient system operating temperature of 0 °C to 45 °C.
  • Note Typical specifications of National Instruments modules might not apply when used in a system with NI Powertrain Control modules.
  • Note National Instruments guarantees warranted specifications for all National Instruments modules except thermocouple modules when used in a system with NI Powertrain Control modules.
  • Note National Instruments recommends the NI 9214 for thermocouple measurements in CompactRIO systems using NI Powertrain Control modules.
  • Note NI Powertrain Control modules do not support Scan Interface mode, auto-detection, or ID mode.

ESTTL Outputs

Each TTL output channel has a DO pin to connect a device that accepts a digital command signal from 0 V to 5 V. The eight output channels are internally referenced to COM, so you can use any of the nine COM lines as a reference for the external signal. Each channel has a pull-down resistor and includes overcurrent, overvoltage, and short-circuit protection.

Overcurrent Protection
The NI 9754 allows only a specified amount of current for switching output channels or sourcing the output load. If the NI 9754 goes into an overcurrent state by exceeding the specified maximum switching frequency or the output load, the power supply begins to drop in voltage until it completely turns off or the overcurrent condition is removed. When the NI 9754 is in this state, it can accept new output state data.

Overvoltage Protection
The TTL outputs of the NI 9754 are temporarily protected from +/-30 V one channel at a time. Continued exposure to overvoltage conditions will degrade the life of the NI 9754.
