Technical Specifications Shared Redundancy Memory Size: 16MB Backplane Power Consumption: 350mA @5VDC Redundancy Communication Interface: Dedicated differential high‑speed sync port Dielectric Isolation Voltage: 1500V RMS Operating Ambient Temperature: 0°C to +60°C Storage Temperature: ‑40°C to +85°C Relative Humidity: 5%‑95%, non‑condensing Certification: CE, UL, cUL
Functional Features ED‑revision optimized internal hardware circuit. Real‑time bidirectional data mirroring between dual CPUs. Built‑in diagnosis for redundancy link faults. Front‑panel LED status indication for operation status. Full mechanical and electrical compatibility with standard RX7i chassis backplane.
Application Scenarios RX7i hot‑standby redundant system spare‑part replacement High‑reliability industrial control cabinet Projects requiring ED hardware revision redundancy memory hardware
Performance Parameters Low‑delay synchronization for redundancy data. Accurate real‑time recognition of link faults. Shock and Vibration: Complies with IEC 60068 industrial environmental standard
Material Composition Module housing: Flame‑retardant high‑strength industrial plastic PCB substrate: FR‑4 high‑temperature resistant printed‑circuit board Bus contact fingers: Gold‑plated copper alloy Internal components: ED‑revision industrial‑grade memory and signal processing chips
Structural Characteristics Standard RX7i plug‑in rack module form factor. Front‑panel multi‑color LEDs show sync activity, link status and fault alarm. Dedicated high‑speed differential redundancy signal connector. Gold‑plated backplane bus contact fingers. Internal ED‑revision memory and differential signal processing circuit assembly. Spring‑loaded mechanical locking latch.
Working Principle Its core working logic matches standard IC698CMX016. Primary CPU runtime data continuously writes into shared memory region. Standby CPU keeps reading mirrored datasets to maintain synchronized state. ED revision tunes internal components. It improves long‑term stability without changing external interfaces or functions.
Installation Requirements Mount the module into dedicated redundancy slot within RX7i redundant chassis. Finish cabinet protective earthing work. Use original matched redundancy cable for paired hardware interconnection. Route redundancy signal wiring away from high‑voltage power cables.
Usage Notes Pair it with matching redundancy memory module under redundant architecture. Check cable connection condition periodically.
