Architecture Overview: A robust, RF-transparent DIN-rail enclosure houses the local webserver and network gateway. A remote, wireless Phidgets bridge communicates state changes from a ruggedized industrial pushbutton over the local Wi-Fi network.
| Component | Manufacturer / Model | Purpose & Specifications |
|---|---|---|
| Main Cabinet Infrastructure (RF-Transparent) | ||
| Enclosure | Altelix 14x11x5 Polycarbonate NEMA | Houses DIN rail and 120VAC outlet. Polycarbonate material allows unimpeded Wi-Fi broadcast to the remote Phidget bridge. |
| Power Supply | Mean Well HDR-30-5 | 5V DIN-Rail PSU. Direct hardwire to Pi and router for maximum stability. |
| Network Gateway | GL.iNet GL-AXT1800 (Slate AX) | OpenWrt-compatible router to act as a downstream gateway and Wi-Fi access point for the wireless bridge. |
| Compute Engine | Raspberry Pi 4 (4GB) | Local webserver host. |
| Compute Housing | Phoenix Contact RPI-BC | Industrial DIN-rail mounting bracket for the Raspberry Pi. |
| Storage | SanDisk Industrial MicroSD | High-endurance storage to prevent corruption from sudden power losses or constant read/writes. |
| Remote Interface (Wireless) | ||
| Wireless Bridge | Phidgets HUB5000_0 (VINT Hub) | Connects to the GL.iNet router via Wi-Fi to transmit button state changes back to the Pi. |
| Signal Isolator | Phidgets DAQ1300_0 | Isolated digital input module. Protects the hub from static or surges originating at the button. |
| Physical Input | Schneider Electric Harmony XB4 | 22mm metal NEMA-rated momentary pushbutton. Heavy-duty construction for chaotic environments. |
| Essential Accessories | ||
| Cable Management | Nylon Cable Glands (Assorted) | Strain relief and dust-sealing for incoming AC power and upstream Ethernet entering the Altelix enclosure. |
| Mounting Hardware | DIN Rail End Brackets | Metal stops to prevent the Pi, Router, and PSU from sliding off the rail due to vibration. |
