# Industrial Specification: Data Acquisition &amp; Processing Unit

## 1. Technical Definition
A specialized electronic component within the Automated Metrology Module responsible for collecting, digitizing, and preprocessing measurement data from sensors before transmission to the control system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-10 VDC input range, 16-bit resolution, 100 kS/s sampling rate, -40°C to 85°C operating temperature**. Failure boundary: **Input voltage exceeding 12 VDC causes ADC saturation, sampling rate dropping below 10 kS/s violates Nyquist criterion for 5 kHz signals, temperature exceeding 90°C triggers thermal shutdown**, Mechanism: **Semiconductor junction breakdown at 12 VDC due to reverse bias voltage exceeding PN junction breakdown voltage, thermal runaway in CMOS circuits above 90°C due to positive temperature coefficient of leakage current**.

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

> **Primary Equation**: $u_c = \sqrt{\sum u_i^2}$
