# Industrial Specification: Control Panel (PLC/HMI)

## 1. Technical Definition
Integrated control interface for monitoring and operating the depyrogenation tunnel's heating, conveyor, and sterilization processes.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **24V DC ±10% (21.6-26.4V), 0-60°C ambient temperature, 5-95% relative humidity non-condensing**. Failure boundary: **Voltage drop below 18V DC causes PLC processor halt, temperature exceeding 70°C triggers thermal shutdown of HMI display backlight**, Mechanism: **Semiconductor junction breakdown at 18V insufficient gate voltage, liquid crystal alignment degradation above 70°C glass transition temperature**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| 24V power supply ripple exceeding 500mV peak-to-peak | 8 | PLC analog input signal distortion causing ±5°C temperature measurement error | Install π-filter (100μF electrolytic + 100nF ceramic) at power entry point with 1Ω series resistor |
| Conductive dust accumulation exceeding 10mg/cm² on HMI touchscreen | 8 | Capacitive touch sensor false triggering at 5pF parasitic capacitance threshold | IP65-rated sealed front panel with 0.5mm neoprene gasket and positive pressure purge system |
