The **PPC-L62T-R80-AXE** is an industrial-grade Panel PC, typically part of the Advantech PPC series. It is designed for HMI (Human Machine Interface) applications in harsh environments. Below is a breakdown of its key electronic components and technical specifications. --- ### 1. Core Processing & Memory The internal electronics are centered around a low-power, high-efficiency architecture designed for 24/7 operation. | Component | Specification | | :--- | :--- | | **CPU** | Intel Atom N270 (1.6 GHz) or similar low-power Intel mobile processor. | | **Chipset** | Intel 945GSE + ICH7M. | | **RAM** | 1x 200-pin DDR2 SO-DIMM socket (Supporting up to 2GB). | | **Storage** | Support for 2.5" SATA HDD/SSD and a CompactFlash (Type II) slot. | --- ### 2. Display and Touch Interface The front-facing electronics involve the LCD panel and the digitizer controller. * **LCD Panel:** 6.5" TFT LCD. * **Resolution:** 640 x 480 (VGA). * **Touch Controller:** Analog resistive 5-wire touch screen connected via internal USB or RS-232 interface. * **Backlight:** CCFL or LED-based (depending on the specific revision), usually featuring high MTBF (Mean Time Between Failures) for industrial longevity. --- ### 3. I/O Connectivity & Circuitry The main logic board (motherboard) integrates various controllers to handle industrial peripherals: | Port Type | Description | | :--- | :--- | | **Ethernet** | Dual 10/100/1000 Mbps RJ-45 ports (Intel 82574L / 82567V controllers). | | **Serial Ports** | 2x RS-232, 1x RS-232/422/485 (Software selectable). | | **USB** | 2x USB 2.0 ports. | | **Audio** | AC’97 or HD Audio codec with internal 1W speakers. | | **Expansion** | 1x PCI slot or 1x PCIe slot (depending on the riser card configuration). | --- ### 4. Power Supply & Protection The power circuitry is designed to handle the fluctuations found in factory floor environments. * **Input Voltage:** Wide range DC input (typically 12V ~ 24V DC). * **Protection:** Includes Over-Voltage Protection (OVP), Over-Current Protection (OCP), and Reverse Polarity Protection. * **Power Adapter:** Usually bundled with a 60W AC/DC power brick for standard AC outlets. --- ### 5. Environmental Ruggedization The electronic parts are mounted within a specific chassis to ensure durability: * **IP Rating:** The front panel is IP65 rated (dust-tight and protected against water jets). * **Cooling:** Fanless design (passive cooling) using heat pipes and aluminum heatsinks to prevent dust intake. * **Watchdog Timer:** 255-level timer to automatically reset the system if the software hangs. ---
