Main Functions

1. Convert electrical bus signals to optical signals for long‑distance communication.
2. Receive optical signal and convert back to electrical signal for controller interaction.
3. High anti‑interference performance, suppress ground loop and strong electromagnetic disturbance.
4. Support point‑to‑point duplex communication for Advant field‑bus extension.
5. Module self‑diagnosis: detect power failure, fiber break, link loss, report fault status.
6. LED status indication:
   • Green LED：Power supply normal, module healthy
   • Yellow LED：Optical link communication active
   • Red LED：Fiber fault / link loss / module hardware fault

Installation & Wiring Requirements

1. Cut off cabinet power before installation or replacement. Mount PFSK151 firmly on DIN‑rail. Hot‑swap is forbidden.
2. Connect 24 V DC power and bus signal wiring strictly per wiring diagram; keep fiber cable separate from high‑power cables.
3. Keep ST fiber connector clean, avoid dust and mechanical damage to fiber end‑face.
4. Complete system grounding according to ABB Advant system specification.
5. After replacement, verify optical link communication status; confirm controller data exchange is normal before commissioning.
6. Replacement note: Check firmware compatibility; optical link loss test is required after replacement.
