The **PPC-412-R750AU** is an industrial-grade Panel PC typically used in automation, human-machine interface (HMI) applications, and edge computing. It is designed to operate in harsh environments while providing the processing power of a desktop system. --- ## 1. Core Processing Unit (CPU) At the heart of the PPC-412-R750AU is the **AMD Ryzen™ Embedded R750** series processor. | Feature | Specification | | :--- | :--- | | **CPU Architecture** | AMD Ryzen™ Embedded R1000/R2000 Series (Variant dependent) | | **Core Count** | Dual-core or Quad-core (typically 2 cores / 4 threads) | | **Graphics** | Integrated AMD Radeon™ Vega Graphics | | **TDP** | Low power consumption (12W - 25W range) for fanless cooling | --- ## 2. Memory and Storage Interface The electronic design emphasizes reliability and data integrity through high-speed interfaces. * **RAM:** Utilizes **DDR4 SODIMM** slots. Many industrial versions support **ECC (Error Correction Code)** memory to prevent data corruption during continuous 24/7 operation. * **Storage:** * **M.2 Slot:** Supports NVMe or SATA SSDs for high-speed OS booting. * **SATA III:** Internal headers for 2.5" industrial SSDs/HDDs. * **Expansion:** Includes Mini-PCIe or M.2 E-key slots for wireless modules (Wi-Fi/BT) or 4G/5G LTE modules. --- ## 3. Display and Touch Electronics The "412" designation usually refers to the 12.1-inch display category. * **Panel Type:** TFT LCD with LED Backlighting. * **Touch Controller:** Multi-touch **Projected Capacitive (P-CAP)** touch screen. The controller is usually connected via an internal USB or I2C interface to the motherboard. * **Brightness:** High-nit options (often 500-1000 nits) for sunlight readability. --- ## 4. I/O Connectivity (Electronic Ports) The motherboard integrates various industrial communication controllers: | Port Type | Electronic Implementation | | :--- | :--- | | **Ethernet** | Dual Gigabit Ethernet (GbE) using Intel or Realtek controllers. | | **Serial Ports** | RS-232/422/485 (Software selectable) for legacy PLC connections. | | **USB** | USB 3.2 Gen 2 ports for high-speed peripheral data transfer. | | **Video Out** | DisplayPort or HDMI for dual-display setups. | --- ## 5. Power Supply and Protection Industrial electronics require robust power management to survive voltage spikes. * **Wide DC Input:** Typically supports **9V to 36V DC** input. * **Protection Circuits:** * **OVP:** Over-Voltage Protection. * **OCP:** Over-Current Protection. * **Reverse Polarity Protection:** Prevents damage if power leads are swapped. * **Isolation:** Some models feature 2.5kV isolation for COM and LAN ports. --- ## 6. Physical Construction (Environmental) * **Cooling:** Fanless design using an aluminum heatsink chassis to dissipate heat from the AMD Ryzen CPU. * **IP Rating:** The front bezel is typically **IP65/IP66** rated, meaning the electronic seals prevent dust and water ingress.
