Main Functions

1. High‑speed timing‑pulse pre‑processing: Receives trigger‑related digital commands from main processor, completes high‑precision timing‑logic pre‑processing, outputs processed pulse signals to valve trigger interface board.
2. Power‑valve feedback‑signal logic processing: Receives status feedback signals from thyristor power valve unit, completes filtering and logic judgment, transmits valid status data to main processor.
3. Inter‑board high‑speed data forwarding: Realizes high‑speed data exchange between main processor and other functional boards inside rack, optimizes real‑time performance of control loop.
4. Hardware‑level time‑sequence monitoring: Monitors trigger‑pulse time‑sequence validity, detects pulse loss and time‑sequence abnormality, reports fault codes to main processor.
5. Daughter‑board expansion support: Provides multiple internal slot interfaces for supporting plug‑in daughter‑boards, expands system signal‑processing capacity for large‑capacity unit configuration.
6. Board‑level comprehensive self‑diagnosis: Monitors on‑board power‑supply, FPGA logic and back‑plane link status; uploads hardware‑fault‑alarm information to UNITROL6000 system.
7. On‑board multi‑LED status indication
   • Green LED：Board power supply normal, board logic running healthy
   • Yellow LED：High‑speed signal processing & data transmission active
   • Red LED：Time‑sequence fault / board hardware fault alarm

Installation & Wiring Requirements

1. Cut off cabinet total power before disassembly and assembly. Insert UDD406A into designated rack slot and fasten fixing screws firmly. Hot‑swap is strictly forbidden.
2. Confirm internal daughter‑board plug‑in status; connect 24 V DC power‑supply terminals strictly according to drawing.
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 parameters; perform back‑plane link test and trigger‑time‑sequence function test before unit commissioning.
5. Replacement note: Cannot run independently; must match corresponding main‑processor hardware and full‑system firmware version.
