Main Functions

1. Pulse signal receiving, reshaping and distribution：Receive firing‑pulse commands from main control board; reshape and amplify pulse signals, distribute multi‑channel synchronized isolated trigger pulses to drive thyristor rectifier bridge for excitation‑current regulation. Maintain sharp pulse edges to guarantee reliable turn‑on of power semiconductors.
2. High‑voltage galvanic isolation：Isolate low‑voltage control‑logic circuit and high‑energy pulse power circuit, prevent high‑voltage surge from penetrating into main controller hardware.
3. Real‑time pulse‑channel status monitoring：Detect pulse loss, pulse‑channel open‑circuit or short‑circuit, pulse‑output abnormality.
4. Fault diagnosis & fault‑code upload：Detect pulse‑driver circuit failure, power‑supply abnormal, board hardware fault. Fault information is uploaded to excitation controller, displayed on local HMI and remote DCS alarm system for troubleshooting.
5. On‑board multi‑LED status indication
   • Green LED：Board 24 V auxiliary power supply normal, back‑plane bus link ok
   • Yellow LED：Pulse‑output active
   • Red LED：Pulse‑channel fault / board hardware failure
6. Signal‑integrity optimization：Suppress high‑frequency interference inside power cabinet, avoid pulse distortion caused by long‑distance internal wiring of cabinet, improve anti‑interference performance of trigger pulse loop.

Installation & Wiring Requirements

1. Insert board into standard Euro‑card cabinet slot, lock front‑panel handles; ensure back‑plane gold‑finger connector fully engaged. Hot‑swap is strictly forbidden; cut off cabinet total power before disassembly and assembly.
2. Ensure cabinet ventilation and heat dissipation; avoid conductive dust and corrosive gas accumulating on PCB surface.
3. Pulse‑output field wiring must be separated from high‑power main‑circuit busbar, route in independent cable ducts to reduce interference coupling.
4. Cabinet protective grounding must strictly follow ABB UNITROL / PCS6000 system grounding specification to guarantee isolation performance and anti‑interference capability.
5. Verify 24 V DC logic power supply within allowable tolerance; over‑voltage will cause permanent hardware damage.
6. After replacement, verify firmware compatibility with main CPU board; perform pulse‑phase‑sequence check according to project parameters.
