FPGA I/O Modules

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

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

Application Areas

The FPGA I/O modules provide a high number of the digital and analog I/O channels needed for applications such as electric drives. To include more I/O channels to the DS6601, DS6602, and DS2655 FPGA Base Boards, you can connect up to five I/O modules to each of the boards.

For the DS2655M1, there is also the DS5450 SC module, available as an add-on. It contains five switchable transformers for decoupling the five DAC channels of the DS2655M1 module from system ground.
