Technical Specifications: Input Signal Type: Fiber reflective memory signal, VME bus differential signal Input Voltage Range: +5VDC bus power supply Input Impedance: Standard VME‑bus impedance Input Current: Typical operating current, maximum limited current Response Time: Deterministic microsecond‑level latency Channel‑to‑Backplane Isolation Voltage: 500V RMS Transient Surge Suppression: 1500V Operating Power Supply: +5VDC Communication Protocol: VME64 backplane bus protocol, reflective memory fiber protocol Operating Temperature: 0 °C to +60 °C Storage Temperature: -50 °C to +85 °C Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Standard 6U single‑slot VME rack module Certifications: CE, UL, industrial EMC standard compliance
Functional Features: Deterministic real‑time shared‑memory data synchronization among multiple distributed nodes. Hardware filter circuit suppresses industrial electromagnetic interference. Hardware fault detection for fiber link and VME‑bus channel condition. Integrated self‑diagnosis for link, power supply and internal circuit status. 
Application Scenarios: Distributed VME‑bus control rack system. Hardware‑in‑loop real‑time simulation platform. Multi‑rack coordinated control for power generation equipment. Distributed control units for large‑scale petrochemical plant. Low‑latency safety interlock control system.
Structural Characteristics: Standard 6U single‑slot plug‑in VME module structure. Front‑panel LED indicators for power, link fault and communication status, fiber interface. Front‑panel optical port for inter‑rack fiber connection. Golden‑finger connector for VME backplane bus interconnection.
Working Principle: Incoming fiber signals from other nodes and VME‑bus signals from backplane go into module. Hardware filter eliminates high‑frequency noise. Isolation unit achieves electrical separation between backplane bus and local logic. Reflective‑memory controller executes shared‑memory mapping and cross‑node data synchronization.
Installation Requirements: Install module into designated slot of standard 6U VME rack. Follow system specification strictly for cabinet grounding implementation. Optical fiber must obey minimum bending‑radius restriction. Keep fiber path away from power cables.
