Description

Hardware & Electrical Specifications

• Model：PFSK152
• Part Number：3BSE018877R2
• Module Type：Fiber‑Optic Communication Module
• Mounting：DIN‑rail mounting, IP20
• Power supply：24 V DC, power consumption 8 W
• Optical interface：Dual‑channel duplex ST fiber connector
• Transmission medium：Multimode optical fiber
• Max transmission distance：2000 m

Main Functions

1. Convert electrical control bus signal into optical signal for long‑distance transmission.
2. Receive optical signal and convert back to electrical signal for controller and remote I/O communication.
3. Eliminate ground loop disturbance and strong electromagnetic interference in heavy‑industrial environment.
4. Point‑to‑point duplex fiber communication for Advant system bus extension.
5. Module self‑diagnosis: detect power failure, fiber break, optical link loss, report fault status.
6. LED status indication:
   • Green LED：Power supply normal, module healthy
   • Yellow LED：Fiber 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 PFSK152 firmly on DIN‑rail. Hot‑swap is forbidden.
2. Wire 24 V DC power and bus signal strictly follow wiring drawing; lay fiber cable separately from high‑power cables.
3. Keep ST fiber connector end‑face clean, prevent dust and scratch damage.
4. Perform protective grounding according to ABB Advant system specification.
5. After replacement, test optical link attenuation and verify bus data exchange before commissioning.
6. Replacement note: Confirm firmware compatibility; do not directly swap with PFSK151 without function verification.
