The **PPC-6121-R8IA** is a specialized industrial panel PC designed by IEI Integration Corp. It is built to serve as a Human-Machine Interface (HMI) in harsh environments, featuring a 12.1-inch display and a modular internal architecture. Below is a breakdown of its core electronic components and technical specifications. --- ### 1. Core Computing Architecture The system is built around an Intel-based architecture designed for a balance between processing power and thermal efficiency. | Component | Specification | | :--- | :--- | | **Processor (CPU)** | Intel® Core™ i5/i3 or Celeron® processor (Socket G2) | | **Chipset** | Intel® HM65 Chipset | | **Memory (RAM)** | 2 x 204-pin DDR3 SO-DIMM slots (Up to 16GB) | | **Graphics** | Integrated Intel® HD Graphics | --- ### 2. Display and Touch Interface The front panel integrates the visual and tactile components necessary for industrial operation. * **LCD Panel:** 12.1" TFT LCD with a resolution of 1024 x 768 (XGA). * **Touch Controller:** 5-wire resistive touch screen. This type of touch sensor is chosen for industrial use because it can be operated while wearing gloves and is resistant to dust and water. * **Backlight:** LED backlight with a Mean Time Between Failure (MTBF) of approximately 50,000 hours. --- ### 3. Internal Connectivity & Expansion The PPC-6121-R8IA is notable for its expansion capabilities, allowing it to interface with legacy industrial hardware. * **Expansion Slots:** * One PCIe x16 slot (for high-speed expansion cards). * Two PCI slots (for legacy industrial interface cards). * **Storage Interface:** 2 x SATA 3Gb/s ports for HDD/SSD integration. * **Networking:** Dual GbE (Gigabit Ethernet) controllers for redundant network connections. --- ### 4. Input/Output (I/O) Electronic Interfaces The rear and bottom I/O panels provide various electronic signaling standards: | Port Type | Quantity | Purpose | | :--- | :--- | :--- | | **USB 2.0** | 4 | Peripheral connectivity (Keyboard, Mouse, Sensors) | | **RS-232** | 2 | Serial communication for legacy PLC/Sensors | | **RS-422/485** | 1 | Long-distance differential serial communication | | **VGA** | 1 | External monitor output | | **Audio** | 2 | Line-out and Mic-in (Realtek ALC892 codec) | --- ### 5. Power Supply & Thermal Management * **Power Input:** Usually supports a wide range DC input (9V ~ 36V) or a standard 12V DC input depending on the specific power module installed. * **Cooling System:** Uses a robust fan-based cooling system designed to pull heat away from the socketed CPU, ensuring the electronics do not throttle under high ambient temperatures. * **Construction:** Heavy-duty aluminum front bezel which acts as a heat sink and provides IP65-rated protection against water and dust.
