The **TPC-312-R853B** is an industrial-grade panel PC manufactured by Advantech. It is designed for human-machine interface (HMI) applications in harsh environments. Below is a breakdown of its primary electronic components and specifications. --- ### 1. Core Processing & Memory The "brain" of the device is centered around low-power, high-efficiency architecture to support fanless operation. | Component | Specification | | :--- | :--- | | **Processor (CPU)** | Intel® Elkhart Lake Celeron® J6412 (Quad Core, 2.0 GHz) | | **System Memory** | 8GB DDR4 SO-DIMM (Expandable up to 32GB) | | **Graphics** | Integrated Intel® UHD Graphics | | **BIOS** | AMI UEFI | ### 2. Display & Touch Interface The front-facing electronics define the user interaction experience. * **LCD Panel:** 12.1" XGA TFT LCD with a resolution of 1024 x 768. * **Backlight:** LED-based with a lifespan of approximately 50,000 hours. * **Touch Controller:** 5-wire resistive touch screen (indicated by the **"R"** in the model name). This allows for operation with gloves or in wet conditions where capacitive touch might fail. ### 3. I/O Connectivity (Electronic Interfaces) The TPC-312-R853B provides various ports to interface with industrial machinery. | Interface Type | Quantity/Description | | :--- | :--- | | **Ethernet** | 2 x 2.5GbE (Intel i225) | | **USB Ports** | 2 x USB 3.2 (Gen 2), 2 x USB 2.0 | | **Serial Ports** | 1 x RS-232, 1 x RS-232/422/485 | | **Audio** | 1 x Line-out | | **Expansion** | 1 x M.2 (B Key), 1 x mPCIe (for Wi-Fi or LTE modules) | ### 4. Power & Thermal Management Industrial electronics require robust power protection and heat dissipation. * **Input Voltage:** 24VDC (±20% tolerance). * **Protection:** Includes over-voltage, over-current, and reverse-polarity protection. * **Thermal Design:** Fanless heat-sink architecture. The aluminum alloy enclosure acts as a passive radiator to dissipate heat from the CPU and internal circuitry. --- ### 5. Storage Support The device uses solid-state electronic storage to ensure high vibration resistance. * **Primary Slot:** 1 x M.2 (M Key) 2280 SATA/PCIe interface. * **Secondary:** Internal 2.5" SATA HDD/SSD bracket (optional).
