# Industrial Specification: Output Relay Module

## 1. Technical Definition
An electrical switching component within a temperature control panel that converts low-power control signals into high-power outputs to activate heating, cooling, or alarm devices.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **5-30 VDC control voltage, 0-10 A switching current at 250 VAC maximum**. Failure boundary: **Contact welding at 35 A sustained current for 500 ms, insulation breakdown at 600 VAC dielectric strength**, Mechanism: **Joule heating exceeding 125°C contact temperature causes contact material annealing and welding; dielectric breakdown occurs when electric field strength exceeds 15 kV/mm in air gaps**.

### 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.
