# Industrial Specification: Station Controller (PLC/I/O)

## 1. Technical Definition
A programmable logic controller (PLC) with integrated input/output (I/O) modules that manages and coordinates the operations of an individual assembly station within a production line.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **24 VDC ±10% (21.6-26.4 VDC) at 2 A continuous current**. Failure boundary: **Dielectric breakdown at 1500 VAC for 1 minute between I/O terminals and ground, or thermal shutdown at 85°C junction temperature**, Mechanism: **Electromigration in aluminum interconnects at current densities exceeding 1×10⁵ A/cm², causing open circuits in PLC processor**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$  
> **Engineering Impact**: Governs heating element sizing for shrink tunnels/sealers.
