The C66xx series includes two versions with either the Intel Core2 Duo
or Core2 Quad processors on the vendor’s ATX motherboard. These control
cabinet PCs are equipped with top-performance components and are
available in two versions: the C6640 with a more compact design, and
the C6650 with up to two hard drives built into removable frames,
making the PC suitable for RAID applications. Measuring just
370x305x200mm (14.6x12x7.9in.), the C6640 is the more compact
Industrial PC in the C66xx series. All connections face upward, so that
the connection cables can be fed directly into the cable channel.
Adding only slightly to the width and height, the C6650 is equipped
with two hard drives built into removable frames, which together with
the on-board RAID controller, form a RAID 1 system with two mirrored
hard drives. Beckhoff Automation LLCwww.beckhoffautomation.com/c66xx952.890.0000
