# Industrial Specification: Data Acquisition Unit

## 1. Technical Definition
Electronic component that collects and digitizes sensor data for monitoring systems

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-10 VDC input, -40°C to 85°C ambient temperature, 0-100% relative humidity (non-condensing)**. Failure boundary: **Input voltage exceeding 12 VDC causes analog-to-digital converter saturation, ambient temperature exceeding 125°C triggers thermal shutdown, moisture ingress exceeding IP65 rating leads to corrosion**, Mechanism: **Semiconductor junction breakdown at 12 VDC due to reverse bias voltage exceeding 0.7 V silicon diode threshold, thermal runaway above 125°C where heat generation exceeds dissipation rate, electrolytic corrosion when chloride ions exceed 15 ppm in presence of moisture**.

### 2.1 Analytical Physics Model
Governed by the **Combined Measurement Uncertainty**:
