DS4004 HIL Digital I/O Board

96 bidirectional digital I/O channels with signal conditioning

The DS4004 HIL Digital I/O Board enables a flexible HIL simulation for widely varying configurations of body electronics. The DS4004 provides 96 digital I/O channels with signal conditioning. Each channel is software-configurable as digital I/O or timing I/O. The DS4004 can be connected to up to six independent external supply voltages.

  • 96 digital I/O channels with general signal conditioning up to 60 V
  • Measures and generates automotive signals and TTL signals
  • All channels configurable via software 

Key Benefits

The DS4004 comprises 96 digital I/O channels with signal conditioning for customary TTL levels and typical automotive systems with electrical system voltages of 12 V, 24 V, 36 V, and 48 V. The 96 digital I/O channels of the DS4004 are arranged in three identical groups, each with two different voltage systems, ranging from 5 V to 60 V. Each of the 96 I/O channels of the DS4004 can be configured via software as digital I/O for PWM measurement or PWM generation, for frequency measurement, or for square wave generation. The digital I/O channels can be used individually, or synchronized in 32-bit words. You can set the values of the I/O channels for the initialization phase and for terminating the model.

Application Areas

The automotive signal conditioning on the DS4004 HIL Digital I/O Board is a cost-efficient way to start using HIL simulation for body electronics ECUs. The DS4004 can be used hassle-free and at low cost in an expansion box, dSPACE Simulator Mid-Size, and dSPACE Simulator Full-Size. These simulators are frequently used to test body electronics ECUs with the DS4004.
