The compact C6640 industrial PC is equipped with top-performance components with Intel® Celeron®, Pentium® or Core™ i3/i5/i7/i9 of the latest generation on an ATX motherboard.
Industrial design
All slots are available for plug-in cards with a length of up to 210 mm. Graphics and Ethernet adapters are already available on-board, without taking up a slot.
All PC connections face upwards, so that the connecting cable can be taken directly to the wiring channel. The side walls are completely passive, and allow the Industrial PC to be fitted immediately next to other control cabinet devices.
Component accessibility
The C66xx series is designed for optimum space utilization and easy accessibility of all components. The C6640 is the most compact PC with an ATX motherboard but nevertheless offers convenient access to drives, memory and plug-in cards.
Maximum data availability and security
The C66xx Industrial PCs are equipped with an M.2 SSD on the motherboard. The option is also available to install a second M.2 SSD that occupies one plug-in card slot to create a RAID 1 system with two mirrored SSDs. This ensures a high level of data security. A further option is available to order up to two hard disks of up to 4 TB for storing large amounts of data.
Flexible expansion options
The housing design of the C66xx series ensures long-term compatibility with new PC components. The motherboard, processor, memory or hard disk are upgradable, while the same housing can be used for years to come.
The device can be equipped with a multi DVD drive. Card holders for the plug-in cards ensure resistance to impacts and vibrations. The C6640 is supplied with a 100 to 240 V AC full range power supply unit. A 24 V DC power supply is available as an alternative, optionally with UPS, so that an external battery can be connected.
A nameplate is located on the top of the front cover, giving detailed information about the PC configuration.
The housing design offers plenty of scope for adjustment to the respective application.
