B&R X20CP3484-1
Intel Celeron 266 Performance with additional I/O processor Ethernet, POWERLINK and USB onboard 3 slots for modular interface expansion CompactFlash as removable application memory Fan-free Extremely compact The X20CP3484-1 is the smallest Celeron based CPU for the X20 System. However, its shortest cycle time of 800 µs still shows its power. The basic features are the same as those of the larger types. Ethernet and USB are onboard. In addition, the CPU has a POWERLINK connection for real-time communication. There are also three multi-purpose slots for additional interface modules. The CPU models X20CP3484 and X20CP3484-1 differ only by SDRAM size.
