The **TPC-312-R833B** is a specific industrial Panel PC manufactured by Advantech. It is designed for human-machine interface (HMI) applications in harsh industrial environments. Below is a breakdown of its primary electronic components and technical specifications. --- ### 1. Core Processing Unit (CPU) The "R833B" designation typically refers to the internal board configuration. * **Processor:** Intel® Atom™ E3845 Quad-Core processor. * **Clock Speed:** 1.91 GHz. * **Architecture:** x86 64-bit, offering a balance between low power consumption (TDP 10W) and sufficient processing power for automation software. ### 2. Display and Touch Interface | Feature | Specification | | :--- | :--- | | **Panel Size** | 12.1" TFT LED LCD | | **Resolution** | 1024 x 768 (XGA) | | **Luminance** | 600 cd/m² (High brightness for industrial visibility) | | **Touch Type** | 5-wire Resistive Touch (Ideal for use with gloves) | | **Backlight Life** | 50,000 hours | ### 3. Memory and Storage * **RAM:** Supports DDR3L 1333 MHz SO-DIMM (usually comes with 4GB, expandable to 8GB). * **Storage Interfaces:** * 1 x mSATA slot for OS and application storage. * 1 x 2.5" SATA SSD/HDD bay for high-capacity data logging. ### 4. Input/Output (I/O) Connectivity The electronic "brain" of the unit communicates with factory equipment via several physical ports: * **Ethernet:** Dual 10/100/1000 Mbps RJ45 ports (Intel I210). * **Serial Ports:** 1 x RS-232, 1 x RS-232/422/485 (for PLC communication). * **USB:** 1 x USB 3.0 and 3 x USB 2.0 ports. * **Expansion:** 1 x Full-size Mini PCIe slot for Wi-Fi, Bluetooth, or Fieldbus modules. ### 5. Electrical Power Requirements * **Input Voltage:** 24VDC (+/- 20% tolerance). * **Power Consumption:** Typical load is approximately 18W to 40W depending on peripheral usage. * **Protection:** Includes reverse polarity protection and chassis grounding to prevent damage from electrical surges. --- ### Summary of Key Features * **Fanless Design:** The electronic components are cooled via a passive heatsink (the aluminum chassis itself), preventing dust intake. * **Ingress Protection:** The front panel is IP66 rated, meaning the electronics are protected against high-pressure water jets and dust. * **Operating Temp:** Rated for -20 ~ 60°C (-4 ~ 140°F).
