Description

Hardware & Electrical Specifications

• Model：UFC911B106
• Part Number：3BHE037864R0106
• Module Type：High‑Speed Serial Communication Interface Board
• Bus Interface：Internal high‑speed back‑plane connector for main‑processor interaction
• External Interface：High‑speed serial optical / electrical communication ports
• Power supply：24 V DC cabinet internal power supply (18‑32 V DC)
• Max power consumption：11 W
• Galvanic isolation：≥2000 V AC between external communication side and control‑logic side

Main Functions

1. High‑speed serial communication processing: Executes dedicated high‑speed serial protocol, realizes real‑time bidirectional data transmission between main controller and other functional boards or remote units.
2. Real‑time control‑data transmission: Transmits trigger timing‑sequence data, measurement sampling data, interlock status and fault information across board‑level links.
3. Communication link diagnosis: Detects link break, frame error, signal loss and abnormal transmission, reports communication fault codes to main processor.
4. Data buffering & forwarding: Provides hardware data buffer, optimizes real‑time performance for power‑electronic control loop.
5. Board‑level comprehensive self‑diagnosis: Monitors on‑board power‑supply, communication chip and back‑plane link status; uploads hardware‑fault‑alarm information to UNITROL6000 system.
6. On‑board multi‑LED status indication
   • Green LED：Board power supply normal, board logic running healthy
   • Yellow LED：Serial communication data transmission active
   • Red LED：Communication‑link fault / board hardware fault alarm

Installation & Wiring Requirements

1. Cut off cabinet total power before disassembly and assembly. Insert UFC911B106 into designated rack slot and fasten fixing screws firmly. Hot‑swap is strictly forbidden.
2. Connect high‑speed serial cables or optical fibers to corresponding front‑panel ports; complete shielding grounding for electrical communication cables to restrain electromagnetic interference.
3. Cabinet protective grounding must comply with ABB AC800‑PEC / UNITROL6000 system grounding specification.
4. After replacement, verify full‑system firmware compatibility with main processor board; download matching project configuration parameters; perform communication link test and data‑point verification before unit commissioning.
5. Replacement note: Cannot run independently; must match corresponding main‑processor hardware and full‑system firmware version; verify hardware variant compatibility before cross‑revision replacement with UFC911B101 / B104.
