DS4003 Digital I/O Board1)

Large number of digital I/O channels

The DS4003 Digital I/O Board provides a large number of digital I/O channels for various applications in rapid control prototyping and hardware-in-the-loop simulation.

  • 96 TTL lines (three 32-bit ports)
  • 3 handshake control lines per port
  • 2 interrupts per port plus one on I/O error

Handling digital I/O channels

In rapid control prototyping and hardware-in-the-loop simulation, many digital signals have to be handled. This means that digital I/O lines have to be controlled. The DS4003 Digital I/O Board provides 96 digital I/O lines grouped into three I/O ports of 32 bits, each with handshake and strobe signals.

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.
