# Industrial Specification: State Machine Logic

## 1. Technical Definition
A control logic component that manages sequential operations by transitioning between predefined states based on inputs and conditions.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-5 VDC input signal range, 24 VDC power supply ±10% tolerance**. Failure boundary: **Input signal exceeding 5.5 VDC causes comparator saturation, power supply voltage below 21.6 VDC or above 26.4 VDC disrupts logic circuit operation**, Mechanism: **Semiconductor junction breakdown at 5.5 VDC input due to reverse bias voltage exceeding silicon PN junction breakdown voltage of 5.1-5.5 V, power supply voltage deviation beyond ±10% causes CMOS logic gate threshold voltage misalignment**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Electromagnetic interference from adjacent 480V AC motor starters inducing 50-100 mV noise on signal lines | 8 | False state transition due to noise exceeding 10 mV Schmitt trigger hysteresis window | Shielded twisted pair cabling with 360-degree termination, ferrite chokes on all I/O lines, optical isolation for critical state signals |
| Ambient temperature exceeding 85°C for sustained operation beyond 8 hours | 8 | Timing circuit oscillator frequency drift exceeding ±0.5% causing missed state deadlines | Temperature-compensated crystal oscillator with ±0.1% stability from -40°C to 125°C, thermal management with 5 W/m·K thermal interface material to heatsink |
