Product Details 

IC690RFH008 is an industrial‑grade 8‑port multimode reflective‑memory fiber hub developed by GE Fanuc, specially built for reflective‑memory real‑time industrial communication network, adopting star‑type network architecture instead of traditional daisy‑chain topology.

This hub provides eight independent multimode SFP fiber ports. Each port can connect reflective‑memory node boards. Multiple hubs can be cascaded, and the whole network can support up to 256 nodes. It supports automatic node identification. When one node fails, the hub will automatically bypass the faulty channel, so the fault will not spread to the whole network, greatly improving system reliability.

Equipped with Ethernet management port and RS232 diagnostic serial port. Users can view link status, channel fault information and configure network parameters. Each channel corresponds to independent LED indicator lights, which directly display power‑on, link connection and fault alarm status for quick on‑site troubleshooting.

It adopts standard 19‑inch 1U rack‑mount structure, easy to install in standard control cabinet. The unit uses AC power input, low power consumption and stable long‑time operation performance. It is widely used in power plant turbine control and other high‑speed hard real‑time industrial control scenarios, for old reflective‑memory network maintenance, upgrading and spare‑part replacement.
