DS4004 HIL Digital I/O Board1)

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.

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.

1)The end of life of the dSPACE PHS (peripheral high-speed) hardware for modular systems is planned for December 31, 2024. You can still buy the related products up to and including December 31, 2021. New Releases of dSPACE software will still support the dSPACE PHS hardware for modular systems until at least the end of 2023. After the end of life, no services of any kind will be available for these products. We advise against using the PHS hardware products in new projects. For new projects we recommend that you use SCALEXIO, the latest dSPACE technology for modular real-time systems.
