Main Functions

1. Multi‑channel analog signal acquisition & conditioning: Collects generator voltage, current analog signals, completes filtering, isolation and signal conditioning before A/D conversion.
2. High‑precision A/D conversion: Converts conditioned analog signals into digital measurement values, sends data to main processor board for excitation closed‑loop control calculation.
3. Binary status signal input processing: Samples cabinet auxiliary binary signals, converts field contact status into digital data for system logic judgment and interlock protection.
4. Real‑time measurement data transmission: Transmits measurement data and binary status to main processor via VME back‑plane bus.
5. Input‑channel fault detection: Monitors analog input signal amplitude, detects signal loss, over‑range and channel abnormal condition, reports fault codes to main processor.
6. Board‑level self‑diagnosis: Monitors on‑board power supply, A/D unit and hardware logic running status; uploads hardware fault information to UNITROL6000 system.
7. On‑board multi‑LED status indication
   • Green LED：Board power supply normal, board logic running healthy
   • Yellow LED：Signal acquisition active, data transmission ongoing
   • Red LED：Input‑channel fault / board hardware fault alarm

Installation & Wiring Requirements

1. Cut off cabinet total power before disassembly and assembly. Insert UAC383AE01 into designated VME rack slot, lock front‑panel handles firmly. Hot‑swap is strictly forbidden.
2. Connect generator measurement analog cables and cabinet binary‑signal cables to corresponding terminal blocks; strictly follow excitation cabinet wiring specification; separate high‑power cables and weak‑signal cables to reduce 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 matched project parameters; perform analog‑channel calibration and binary‑input function test before unit commissioning.
5. Replacement note: Cannot operate independently; must cooperate with PPC series main‑processor hardware and matched full‑system firmware version.
