M51 - Mezzanine Card with 4 CAN Bus Interfaces (Product Discontinued)

The mezzanine card M51 is a CAN bus interface M-Module based on the SJA1000. It is available with one or four CAN bus controllers. The M-Module is equally suitable in fieldbus applications and for test and diagnosis equipment for the CAN bus or CAN bus devices. All channels are optically isolated from the system and from each other.

The four-channel version has been designed for example for use of SLIO CAN devices (serial linked I/O) to increase the I/O capabilities of your system in a very cost-effective way.

The M51 also supports network configurations that require high speed with short distances and low speed over long distances.

The M51 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.
