DS2655M1 Multi-I/O Module

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

The DS2655M1 Multi-I/O Module is an I/O module for the DS2655 FPGA Base Board. The module provides five parallel 14‑bit A/D channels, five parallel 14‑bit D/A channels, and ten bidirectional digital I/O channels. The DS2655M1 can be extended by a SC (signal conditioning) for decoupling the five DAC channels of the DS2655M1 module from system ground.

The DS2655M1 Multi-I/O Module can be used with all SCALEXIO FPGA boards.
