# Industrial Specification: Communication Interface Modules

## 1. Technical Definition
Hardware modules that enable data exchange between the Central Control System and external devices or networks.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-70°C ambient temperature, 0-95% relative humidity non-condensing, 4.75-5.25V DC supply voltage**. Failure boundary: **Ambient temperature &gt;85°C sustained for &gt;15 minutes, supply voltage &lt;4.5V or &gt;5.5V for &gt;100ms, electrostatic discharge &gt;8kV contact discharge**, Mechanism: **Semiconductor junction thermal runaway at &gt;150°C die temperature, dielectric breakdown in isolation barriers at &gt;2500Vrms, electromigration in copper traces at &gt;10^6 A/cm² current density**.

### 2.1 Analytical Physics Model
Governed by the **EMI Shielding Effectiveness (SE)**:

> **Primary Equation**: $SE = 20 \log(\frac{E_{in}}{E_{out}})$
