The SA8 is a 1-channel CAN ISO high-speed interface adapter with optical isolation.
SA-Adapters are small universal boards providing the physics for legacy serial I/O, fieldbus interfaces and other small I/O functions. One serial line is provided per adapter, which can be plugged directly to the CPU board as a mezzanine. Alternatively, the adapter can be connected to the front panel via ribbon cable. The SA concept allows to add additional I/O interfaces to many of MEN's CPU boards, enhancing flexibility with regard to the line transceivers and isolation requirements. Whether a specific SA-Adapter (or a mix of different SA-Adapters) fits on a specific CPU board is determined by a combination of mechanical, performance, FPGA and operating system criteriaand needs to be verified for every board configuration requested.
