PACs comes with different numbers of IO slots to customize your system as needed. They can be x86 based and run Windows or Linux or any other PC compatible OS or be ARM based  (Cortex-A8) and typically run WINCE. PACs uses their slot based IO cards for local IO but they can also measure and control a wider area by utilizing remote IO devices over RS485/LAN (Modus etc). The 9000 series is newer and faster.
