NEC FC‑9801F

Technical Specifications: 32‑bit industrial processor; 256 KB SRAM memory; 1 MB ROM memory; power consumption 5 W; operating voltage 24 V DC; operating temperature ‑20 °C ~ +70 °C; storage temperature ‑40 °C ~ +85 °C; communication interfaces RS‑232, RS‑485, Ethernet; support Modbus RTU, DeviceNet industrial protocols; rack‑mount plug‑in structure.

Functional Features: High‑speed execution of industrial control logic; multi‑channel serial and Ethernet communication; built‑in hardware fault diagnosis; status LED indicator; support hot‑swap replacement; fan‑less passive cooling design; ECC memory error detection function; compatible with FC‑9800 series peripheral I/O modules.

Application Scenarios: Manufacturing production line automation control, machine equipment controller, factory process monitoring system, industrial equipment data acquisition, automated assembly‑line control system.

Performance Parameters: Logic instruction execution speed 0.1 μs per step; maximum communication baud rate 115200 bps; MTBF ≥ 120000 hours; memory data retention by backup battery.

Material Composition: FR‑4 industrial‑grade printed circuit board; metal front panel with LED indicators; gold‑plated rack‑mount connector; industrial‑grade processor, memory chips, isolation communication chips; metal alloy housing.

Structural Characteristics: Eurocard plug‑in rack‑mount module; front panel with status indicator lamps and communication connectors; rear high‑density backplane connector; passive cooling without fan, no ventilation holes on front panel.

Working Principle: Industrial processor reads user control program stored in ROM; collects field I/O signals through backplane bus; executes logic and arithmetic operations; outputs control commands to peripheral modules; completes data interaction with upper host computer via serial or Ethernet interfaces; hardware circuit monitors internal operating status and reports fault information.

Installation Requirements: Install in NEC FC‑9800 series standard industrial rack; insert into designated CPU slot; connect 24 V DC power supply according to specification; cabinet requires good ventilation; keep away from strong electromagnetic interference sources; protective ground connection required.

Usage Notes: Implement electrostatic protection during handling; module power must be cut before plug‑out; regularly check backup battery voltage; firmware can only use official release version; prohibit mechanical impact; operating humidity 5%‑95% non‑condensing; do not use beyond rated temperature range.
