# Industrial Specification: Checkpoint Record Manager

## 1. Technical Definition
A component within the Checkpoint Coordinator system that manages and maintains records of checkpoints in industrial processes.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-5.0 VDC signal input range, 24 VDC power supply ±5% tolerance**. Failure boundary: **Signal input exceeding 5.5 VDC causes analog-to-digital converter saturation at 4095 counts, power supply voltage below 22.8 VDC triggers undervoltage lockout**, Mechanism: **Semiconductor junction breakdown at 5.5 VDC due to Zener diode clamping failure, MOSFET gate threshold voltage dropout at 22.8 VDC causing regulator instability**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Electromagnetic interference from variable frequency drives exceeding 85 dBμV/m at 10 MHz frequency | 8 | Bit-flip errors in non-volatile memory causing checkpoint record corruption | Shielded twisted-pair cabling with ferrite chokes and differential signaling using RS-485 protocol with 120Ω termination |
| Thermal cycling between -20°C and +85°C at 5°C/minute rate exceeding 10,000 cycles | 8 | Solder joint fatigue at QFP-64 package leads causing intermittent data bus connection failures | Underfill epoxy application with 12 MPa shear strength and conformal coating meeting IPC-CC-830B Class 3 requirements |
