About Siemens SIMATIC Microbox PC 427B (6ES7647-7AB20-0PA0), PROFIBUS DP (12 Mbps) interface, 1 GB replaceable CompactFlash storage, Windows XP Embedded pre-installed, ultra-compact fanless automation computer
Run robust machine control and centralized industrial data logging inside space-restricted machinery with the legacy Siemens SIMATIC Microbox PC 427B (6ES7647-7AB20-0PA0). Engineered by Siemens for maintenance-free continuous operation, this compact embedded industrial PC features an Intel Celeron M 900 MHz processor paired with 512 MB of high-stability DDR2 system memory. To guarantee zero maintenance vulnerabilities, the system features a purely fanless, diskless mechanical architecture that eliminates rotating wear parts. This setup makes it exceptionally resilient against heavy plant vibrations, high magnetic interference, and thermal stresses.
The primary engineering and hardware-build characteristics of this specific box computer configuration include:
- Embedded Control Communication: Outfitted with an integrated, high-speed PROFIBUS DP interface capable of handling transmission speeds up to 12 Mbit/s to manage legacy distributed slave networks cleanly.
- Industrial-Grade Solid Storage: Houses an easily accessible, front-replaceable 1 GB CompactFlash (CF) card that contains the pre-installed Windows XP Embedded runtime operating system image to prevent data corruption during abrupt power loss.
- Space-Saving Panel Footprint: Encased in a rugged IP20 metal housing measuring 40.50 x 22.00 x 26.40 cm, designed for horizontal or vertical DIN-rail mounting directly adjacent to machine control rails.
Lifecycle & Service Notice: This legacy hardware variant is officially
discontinued and no longer available from active factory production. For modern system migrations, network expansions, or brand-new installations, Siemens recommends evaluating the
SIMATIC IPC427E Microbox PC series driven by modern Intel Core processors to secure long-term firmware protection and future-proof automation compatibility.
