2. Core Features

• Expanded Storage Capacity: 256MB base Flash + 32GB microSD support—accommodates large-scale data requirements (e.g., 1 year of 1-minute interval process logs, 50+ control logic versions) without frequent data purging, reducing administrative overhead.
• High-Speed DDR3 ECC RAM: 64MB DDR3 RAM with 10x faster access speeds than previous generations—enables real-time caching of high-frequency process data (e.g., 1kHz sensor readings in automotive test cells) without latency bottlenecks.
• Dual-Battery Redundancy: Hot-swappable dual lithium batteries provide 144-hour data retention—eliminates single-point failure in power backup, ensuring critical data (e.g., batch parameters in pharmaceutical production) is preserved during extended outages.
• Advanced Data Integrity: SHA-256 encryption for critical files and predictive bad block management—prevents tampering with safety logic (SIL 2 compliance) and alerts maintenance teams before Flash degradation causes data loss, reducing unplanned downtime.
• MicroSD Data Mirroring: Optional real-time mirroring to industrial microSD—enables portable disaster recovery (e.g., transferring configurations to a backup controller) and simplifies data extraction for compliance audits (e.g., FDA 21 CFR Part 11).
• Magnesium Alloy EMI Shielding: Lightweight magnesium housing with enhanced EMI shielding—blocks wideband interference (1MHz~2GHz) from industrial equipment (e.g., high-power inverters, radar systems), ensuring stable memory access in electrically dense environments.
• Extended Temperature Range (-30℃~+70℃): Functions reliably in extreme cold (e.g., arctic oil pipelines) and heat (e.g., desert solar plants)—eliminates the need for heated/cooled enclosures in remote locations, reducing installation costs.
• Seamless S800 Redundancy Integration: Compatible with DSBB175 redundant backplanes—synchronizes memory data between primary/backup controllers in <50ms, ensuring no data loss during failover in safety-critical systems (e.g., refinery emergency shutdown).

3. Application Fields

• Large-Scale Process Control: High-capacity data logging:
  • Petrochemical Refineries: Stores 1-year process logs (via 32GB microSD) and redundant control logic—dual batteries preserve real-time pressure/temperature data during grid outages; ATEX compliance supports use in Zone 2 areas.
  • Mining Operations: Caches high-frequency (1kHz) sensor data (vibration, gas levels) in DDR3 RAM—extended -30℃ operation ensures reliability in underground mines; data mirroring simplifies post-incident analysis.
• High-Speed Manufacturing: Fast data caching:
  • Automotive Test Benches: Uses DDR3 RAM to cache 1kHz torque/speed data from engine tests—high-speed access enables real-time analysis; microSD mirroring stores test results for compliance reporting.
  • Semiconductor Fabs: Stores 50+ versions of wafer processing logic (256MB base Flash)—SHA-256 validation prevents unauthorized logic changes; magnesium housing resists chemical exposure from cleanroom agents.
• Energy & Utilities: Remote data retention:
