A203N - M-Module Carrier Board for 4 Mezzanine Cards

The A203N is an M-Module carrier board for universal I/O on the VMEbus, allowing high flexibility in applications such as process and motion control, measurement and instrumentation, communication or special-purpose tasks. The M-Modules are screwed tightly on the carrier board, and the board needs only one slot on the VMEbus.

The A203N is a VME64 slave card and supports four D16/D32 M-Modules with the signals either at the front or via rear I/O. An interrupt controller handles the M-Modules individually.

For rugged requirements the A203N is equipped with a stiffener front panel, allows a standard -40 °C to +85 °C operation temperature and is prepared for conformal coating.

Additionally, the A203N is prepared for DMA transfer support.
