Central I/O expansion PC IO

The PC IO central I/O expansion is a signal input/output module for the SIMATIC Microbox PC 427B. The I/O mounted into the PC facilitates particularly fast and realtimecapable measuring, e. g. with a response time to a digital or analog input within 100 µsec, for example with pick-and-place machines, robot controls and filling systems. This combination offers a powerful control solution to machine, system and control cabinet manufacturers providing: maximum compactness, high efficiency and flexibility, and minimized costs. The PC IO is equipped with all drivers for application in C/C++-based automation solutions with the realtime operating system RMOS3 as well as applications based on Windows XP Embedded and XP Professional, e.g. WinAC RTX. Highlights PC IO Components Technical Data

Ultra-compact integration of central I/O, e. g. for axis applications with sensor connection

Highlights
