A201S - M-Module Carrier Board for 4 Mezzanine Cards

The A201S is an M-Module carrier board for universal I/O on the VMEbus, allowing high flexibility in applications such as process and motion control, measuring and instrumentation, communication or special-purpose tasks.

The M-Modules are screwed tightly on the carrier board, but the board needs only one slot on the VMEbus. Please note that since all three rows of the P2 connector are used for user I/O, board models with this connector are not compatible with VME64 backplanes.

An interrupt controller handles the M-Modules individually. In VMEbus D16 systems the I/O signals of the M-Modules can be accessed from P2/J2 inside the rack.
