The GE ACC-5595-208 (350-805595-208N) Reflective Memory Managed Hub is a high-performance, real-time data sharing and synchronization device designed for mission-critical industrial and aerospace/defense applications.
Here are its key functions:
1. Real-Time Data Sharing (Reflective Memory Technology)
Enables ultra-low-latency (<500ns), deterministic data sharing between multiple nodes (computers, PLCs, or controllers) across a distributed system.
Creates a shared memory space where all connected devices see identical data simultaneously, eliminating traditional network delays.
2. High-Speed Fiber Optic Network Backbone
Uses fiber-optic connections (typically 2.5Gbps) for noise-immune, long-distance (up to 10km per segment) communication.
Supports ring or star topologies with redundant paths for fault tolerance.
3. Managed Hub Functionality
Acts as an active repeater and switch, regenerating signals to maintain signal integrity across large systems.
Provides network management features like error detection, node status monitoring, and traffic optimization.
4. Deterministic Performance for Critical Systems
Guarantees sub-microsecond latency for time-sensitive applications where traditional Ethernet/IP networks are too slow.
No software overhead – operates at hardware level for consistent performance.
5. Rugged Industrial Design
Built for harsh environments with wide temperature tolerance and vibration resistance.
Supports hot-swapping of nodes for maintenance without system shutdown.
6. Compatibility and Scalability
Works with GE/VMIC reflective memory cards (e.g., ACC-5595 series) and compatible third-party hardware.
Scalable to 256 nodes in a single network.
7. Typical Applications
Industrial Automation: Real-time control of high-speed manufacturing systems
Aerospace/Defense: Flight simulators, radar systems, test platforms
Energy: Power plant control systems
Transportation: Railway signaling systems
