GE VMIACC-5595-208 Reflective Memory Hub Assembly

GE VMIACC-5595-208 is an industrial-grade reflective memory hub designed for real-time, high-speed fiber-optic communication in automation, aerospace, and distributed control systems. As a core component of GE’s reflective memory network, it delivers deterministic data transmission, seamless scalability, and robust reliability for mission-critical applications.

Key Features

8 SFP Fiber Ports: Supports multimode (300–550m) and single-mode (up to 10km) transceivers for flexible network design.

2 Gb/s High-Speed Transfer: 2.125 Gbaud serial rate, up to 174 MB/s throughput; nanosecond-level node-to-node latency (≤750ns).

Auto Bypass Function: Automatically bypasses failed/disconnected nodes in <50ms, ensuring network uptime and data integrity.

Massive Scalability: Cascades up to 256 nodes in star or ring topologies for large-scale industrial networks.

Industrial Hardened Design: IP40-rated, operates reliably in -40°C to +85°C environments.

Remote Management: Equipped with Ethernet (10BaseT) and RS232 ports for easy configuration, monitoring, and control.
