FPGA I/O Modules

For expanding the I/O channels of the dSPACE FPGA base boards

Three I/O modules are available for expanding the I/O channels of the dSPACE FPGA base boards: the DS6651 Multi-I/O Module, the DS2655M1 Multi-I/O Module, and the DS2655M2 Digital I/O Module.

  • Providing a high number of digital and analog I/O channels
  • Three I/O modules available for dSPACE's FPGA base boards
  • Add-on with five switchable transformers

Application Areas

Three I/O modules are available for expanding the I/O channels of the dSPACE FPGA base boards. They provide a high number of the digital and analog I/O channels required for applications such as electric drives:

  • The DS6651 Multi-I/O Module, which provides a tailored channel set for controlling and simulating electric drives and power electronic components.
  • The DS2655M1 Multi-I/O Module with five analog in and out channels as well as ten digital channels. The DS2655M1 can be extended by the DS5450 SC add-on module. The add-on module contains five switchable trans­formers for decoupling the five DAC channels of the DS2655M1 module from system ground.
  • The DS2655M2 Digital I/O Module with 32 digital channels.

The I/O modules can be combined as desired to meet any use case requirements.
