# Industrial Specification: Central Process Control System

## 1. Technical Definition
The central control unit that monitors and regulates all automated operations within a precision casting production line.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **24-48 VDC input voltage, 0-100% CPU load, 0-60°C ambient temperature**. Failure boundary: **Input voltage &lt;22.8 VDC or &gt;50.4 VDC sustained for &gt;100ms, CPU temperature &gt;85°C, ambient temperature &gt;65°C**, Mechanism: **Semiconductor junction thermal runaway at &gt;150°C silicon temperature, electrolytic capacitor electrolyte evaporation at &gt;105°C case temperature, MOSFET gate oxide breakdown at &gt;20V gate-source voltage**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$
