The **TPC-312-R873B** is a high-performance industrial Touch Panel PC manufactured by Advantech. It is designed for demanding HMI (Human Machine Interface) applications, leveraging the Intel 8th Generation Core i7 processor architecture. --- ### ## Core Electronic Specifications | Component | Technical Specification | | :--- | :--- | | **Processor (CPU)** | Intel® Core™ i7-8665UE Quad-Core (1.7 GHz base, up to 4.4 GHz) | | **Memory (RAM)** | 8GB DDR4 SO-DIMM (Expandable up to 64GB) | | **Storage Interface** | 1 x M.2 (M Key) 2280 NVMe/SATA and 1 x 2.5" SATA SSD/HDD | | **Display Panel** | 12.1" XGA TFT LED LCD (1024 x 768 resolution) | | **Touch Controller** | 5-wire Resistive Touch (USB Interface) | | **Power Input** | 24 VDC ± 20% | | **OS Support** | Windows 10 IoT, Linux (Ubuntu/Yocto) | --- ### ### Key Electronic Subsystems #### 1. Processing Power & Logic Unlike entry-level HMI panels that use Atom or Celeron chips, the **R873B** utilizes an **8th Gen Whiskey Lake** processor. This allows for: * **Virtualization support:** Running multiple OS or containers simultaneously. * **TPM 2.0:** Integrated hardware security for encrypted data protection. * **iAMT (Intel Active Management Technology):** Remote management and out-of-band monitoring. #### 2. Display and Touch Layer * **Luminance:** 600 cd/m², making it readable in high-glare industrial environments. * **Backlight Life:** Rated for 50,000 hours. * **Resistive Touch:** The "R" in the model number denotes a resistive touch screen, which is ideal for industrial environments where operators wear thick gloves or where liquid splashes might trigger false inputs on capacitive screens. #### 3. Connectivity & I/O The motherboard provides robust electrical isolation for industrial safety: * **Dual Gigabit Ethernet:** Realtek/Intel controllers for redundant network paths. * **Serial Communication:** 2 x RS-232/422/485 ports with auto-flow control. * **Expansion:** iDoor technology support, allowing the addition of fieldbus protocols (Profinet, EtherCAT, CANopen) via internal mini-PCIe slots. #### 4. Thermal and Power Design * **Fanless Cooling:** The electronic components are heat-synced to the aluminum alloy chassis, preventing dust ingestion. * **Protection:** Includes over-voltage, over-current, and reverse-polarity protection on the power input stage. --- ### ### Environmental Durability The electronic parts are selected to withstand harsh conditions: * **Operating Temperature:** -10 ~ 50°C (14 ~ 122°F). * **Ingress Protection:** The front panel is IP66 rated (dust-tight and protected against powerful water jets). * **Vibration Resistance:** 2 Grms (5 ~ 500 Hz) during operation with SSD.
