Main Functions

1. Genius‑bus signal media converter, converts electrical Genius‑bus signal to optical signal, extends communication transmission distance for Genius distributed I/O network.
2. Provides complete electrical isolation between copper bus segments, suppresses ground‑loop noise and heavy‑industrial electromagnetic interference.
3. Transparent repeater device, no PLC software configuration, does not consume Genius bus address resource.
4. LED status indication:   ‑ Green POWER：Module 24VDC power‑on indicator   ‑ Green LINK‑A / LINK‑B：Fiber‑link status for each optical channel   ‑ BUS‑ACT：Genius‑bus communication activity indicator

Installation & Wiring Requirements

1. Cut off module 24VDC power before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling unit.
2. Mount IC690RFH008 firmly on panel or DIN‑rail; connect multi‑mode ST fiber cables; connect copper Genius‑bus wiring to electrical terminal ports.
3. System wiring strictly follow GE Genius hardware manual; install bus terminator resistor at both physical ends of every copper bus segment; keep fiber path away from high‑voltage / high‑power cables.
4. Complete protective grounding according to GE system specification.
5. After replacement: power‑on module, verify POWER, LINK‑A/B LED status, perform Genius‑bus scan and full I/O‑loop commissioning test.
6. Replacement note: Confirm fiber core cleanliness and ST connector installation; match system Genius baud‑rate; full Genius‑bus‑loop simulation test mandatory before unit put‑into‑service.
