The **TPC-317-R873B** is a high-performance industrial Touch Panel PC (TPC) 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 specifications. --- ### 1. Core Processing & Memory The "R873B" variant typically features the Intel® Core™ i7 processor, providing significant computational power for multitasking and complex automation software. | Component | Specification | | :--- | :--- | | **CPU** | Intel® Core™ i7-6600U (2.60 GHz Dual-Core) | | **RAM** | 8 GB DDR4 (upgradable to 16 GB or 32 GB depending on board revision) | | **Storage** | 2.5" SATA SSD/HDD slot & mSATA support | | **BIOS** | AMI UEFI | ### 2. Display and Touch Interface The unit features a large-format display designed for visibility and durability. * **Panel Size:** 17" SXGA TFT LED LCD. * **Resolution:** 1280 x 1024. * **Touch Type:** 5-wire resistive touch (ideal for use with gloves in industrial settings). * **Luminance:** ~350 cd/m². * **Backlight Life:** 50,000 hours. ### 3. I/O Connectivity & Electronics The mainboard (carrier board) provides various communication interfaces to connect with PLCs, sensors, and enterprise networks. | Interface Type | Quantity/Details | | :--- | :--- | | **Ethernet** | 2 x 10/100/1000 Mbps (RJ45) | | **USB Ports** | 4 x USB 3.0 | | **Serial Ports** | 1 x RS-232, 1 x RS-232/422/485 | | **Video Output** | 1 x HDMI (for secondary display) | | **Expansion** | 1 x Full-size mPCIe slot | ### 4. Power Circuitry Industrial computers require robust power management to handle fluctuations in factory power grids. * **Input Voltage:** 24VDC (±20% tolerance). * **Power Consumption:** Typically 30W to 60W depending on load. * **Protection:** Reverse polarity protection and chassis grounding to prevent ESD damage. ### 5. Mechanical and Environmental Construction * **Enclosure:** Die-cast aluminum alloy front bezel (provides heat dissipation). * **Ingress Protection:** IP66 rated front panel (protected against dust and high-pressure water jets). * **Cooling:** Fanless design (uses the chassis as a heat sink to prevent dust intake). --- ### Typical Wiring Example Below is a conceptual pinout representation for the Power Connector commonly used in this series: ```markdown Pin 1: V+ (24VDC) Pin 2: V- (0V/Ground) Pin 3: Chassis Ground (Earth) ```
