The mezzanine card M56 is an M-Module which has 16 relay channels with throw-over contacts. It is a switching matrix for measuring signals with different voltage levels and different ground references.
The powerless-switching relays offer great advantages: since there are no thermoelectric potentials, the M56 can "process" very small voltage and current.
The M56 is based on the M-Module ANSI mezzanine standard. It can be used as an I/O extension in any type of bus system, i.e. CPCI, VME or on any type of stand-alone SBC. Appropriate M-Module carrier cards in 3U, 6U and other formats are available from duagon or other manufacturers.
