# Industrial Specification: Input Device

## 1. Technical Definition
A component of the Setpoint Interface that allows operators to enter, adjust, or confirm target values (setpoints) for process control.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-24 VDC input voltage, -20°C to +70°C ambient temperature, 0-100% relative humidity (non-condensing)**. Failure boundary: **Input voltage exceeding 30 VDC causes MOSFET gate oxide breakdown, ambient temperature exceeding 85°C triggers thermal shutdown, moisture ingress exceeding IP65 rating leads to electrochemical migration**, Mechanism: **Dielectric breakdown at 6.5 MV/cm electric field strength (SiO₂), semiconductor junction thermal runaway above 150°C, dendritic growth from electrochemical corrosion at &gt;60% RH with contaminant ions**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Electrostatic discharge (ESD) event exceeding 8 kV human body model | 8 | Gate oxide puncture in input protection MOSFET, resulting in permanent short circuit | Integrated silicon-controlled rectifier (SCR) clamp circuit with 5 ns response time, 100 pF capacitor in parallel with 1 kΩ series resistor |
