The **PPC-L128T-R80-XE** is an industrial-grade Panel PC manufactured by **Advantech**. It belongs to the PPC-L128 series, designed for rugged applications such as factory automation, kiosk systems, and environmental monitoring. Below is a breakdown of its primary electronic components and technical specifications. --- ### 1. Core Computing Hardware The "R80-XE" variant typically indicates a configuration involving a specific processor and memory architecture optimized for reliability. | Component | Specification | Description | | :--- | :--- | :--- | | **Processor (CPU)** | Intel Atom or Celeron | Low power consumption, fanless thermal design. | | **Memory (RAM)** | DDR2 / DDR3 (up to 4GB) | Supports industrial-grade SO-DIMM modules. | | **Chipset** | Intel Integrated | Manages I/O operations and graphics processing. | | **Storage** | HDD / SSD / CF Card | Includes a 2.5" SATA bay and often a CompactFlash (CF) slot for OS redundancy. | ### 2. Display and Touch Interface The panel is designed for human-machine interaction (HMI) in harsh environments. * **LCD Panel:** 12.1" TFT LCD display. * **Resolution:** 1024 x 768 (XGA) or 800 x 600 (SVGA) depending on specific sub-revision. * **Touchscreen:** 5-wire Resistive touch sensor. This allows operation while wearing gloves and provides high durability against dust and moisture. * **Backlight:** CCFL or LED (newer versions) with a high MTBF (Mean Time Between Failures) of 50,000 hours. ### 3. I/O Ports and Connectivity The electronic "backplane" provides various interfaces for industrial sensors and networking. | Port Type | Quantity | Purpose | | :--- | :--- | :--- | | **Ethernet** | 2x RJ45 | Dual Gigabit LAN for network redundancy. | | **Serial Ports** | 2x to 4x | RS-232/422/485 for PLC and sensor communication. | | **USB** | 4x USB 2.0 | For peripherals and maintenance. | | **VGA/DVI** | 1x | Support for an external secondary display. | | **Expansion Slot** | 1x PCI/PCIe | For adding specialized fieldbus cards or DAQ modules. | ### 4. Power and Environmental Protection The electronic design emphasizes stability under electrical noise and physical stress. * **Power Input:** 12V ~ 24V DC input (Industrial grade power protection). * **Ruggedization:** The front panel is usually **IP65 rated**, meaning the electronics are protected against water jets and dust. * **Fanless Design:** Uses a heavy-duty heatsink instead of a fan to prevent mechanical failure and dust intake. --- ### Summary of Key Features 1. **High EMI/EMC Compliance:** Designed to operate near heavy machinery without signal interference. 2. **Watchdog Timer:** A hardware electronic timer that automatically resets the system if the software freezes. 3. **Expansion Flexibility:** The R80-XE version often allows for specific riser cards to expand the electronic capabilities via PCI slots.
