B202S - M-Module Carrier Board (Product Discontinued)

The B202S is an M-Module carrier board for universal peripheral input/output applications on the VMEbus. M-Modules are screwed tightly on the carrier board, but the board needs only one slot on the VMEbus. MEN's B202S offers VMEbus developers instant access to more than 70 different M-Modules for I/O in fields such as process I/O, measurement, instrumentation, motion control, communication, and development.
