NEC FC‑9821X MODEL2

Technical Specifications: Industrial‑grade x86 architecture processor; onboard graphics accelerator CIRRUS LOGIC GD5430; support resolution 640×400, 640×480, 1024×768; onboard RAM and ROM storage; operating temperature 0 °C ~ +50 °C; storage temperature ‑20 °C ~ +65 °C; operating humidity 20%‑90% non‑condensing; multiple serial communication interfaces; rack‑mount eurocard structure; CE certification.

Functional Features: Industrial real‑time operating‑system support; integrated graphics display output; multi‑channel serial communication interfaces; hardware watchdog for system fault reset; built‑in power‑failure data protection function; rich expansion bus resources; passive cooling design; anti‑vibration industrial‑grade hardware.

Application Scenarios: Industrial on‑site real‑time monitoring host, production‑line equipment control host, factory automation man‑machine processing unit, industrial test equipment control core, workshop data recording and processing unit.

Performance Parameters: Graphics display supports 256‑color and multi‑million‑color output; hardware watchdog timeout range adjustable; system power‑failure protection for memory data; MTBF ≥90000 hours.

Material Composition: FR‑4 high‑reliability multilayer printed circuit board; metal rack‑mount front panel; gold‑plated eurocard backplane connector; industrial‑grade CPU, graphics chip, memory chips; tantalum capacitor energy‑storage components for power‑failure protection; metal shielding housing.

Structural Characteristics: Eurocard plug‑in rack‑mount structure; front‑panel equipped with status indicator and external interface connectors; rear side high‑density gold‑plated backplane connector connected to system rack bus; integrated on‑board backup battery module for data retention.

Working Principle: Industrial‑grade processor runs real‑time industrial operating‑system and application software; completes field‑data collection and operation calculation via backplane bus; outputs graphics signal to external display equipment; communicates with peripheral industrial equipment through serial interfaces; hardware watchdog monitors system running status and triggers automatic reset upon system crash; backup battery protects memory data when power fails.

Installation Requirements: Install into NEC FC‑9800 series standard industrial rack; insert into specified slot position; cabinet internal temperature must be controlled within 0 °C‑50 °C; shielded cables for display and communication wiring; protective ground connection required; keep away from high‑power interference equipment.

Usage Notes: Electrostatic protection must be adopted during handling; power‑off before module removal; regularly inspect aging status of backup battery; avoid mechanical vibration and impact; operating environment must keep non‑condensing humidity; do not modify internal hardware circuit arbitrarily.
