The **FPM-3171G-RCE** is an industrial-grade 17" SXGA TFT LED LCD monitor designed by Advantech. It is engineered for harsh environments, featuring a rugged design and specific electronic components that differentiate it from standard consumer displays. --- ### Core Electronic Specifications | Feature | Specification | | :--- | :--- | | **Display Type** | 17" SXGA TFT LED LCD | | **Max Resolution** | 1280 x 1024 | | **Luminance (Brightness)** | 350 cd/m² | | **Backlight Lifetime** | 50,000 hours | | **Input Power** | 24 VDC (Phoenix Jack) | | **Power Consumption** | 23W + 20% (Typical) | | **Touchscreen Type** | 5-wire Resistive | --- ### Key Electronic Components & Interfaces #### 1. Display Controller & Interface The unit utilizes an industrial-grade AD (Analog-to-Digital) board to convert standard video signals for the LCD panel. * **Video Inputs:** It supports both **VGA** (analog) and **Direct-VPI** (Video Port Interface). * **OSD (On-Screen Display):** Features rear-mounted buttons for electronic adjustment of brightness, contrast, and image positioning. #### 2. Touchscreen Controller The "R" in the model name signifies the **Resistive** touch technology. * **Interface:** Connects via **USB** or **RS-232 (COM port)** to the host PC. * **Mechanism:** Uses a 5-wire pressure-sensitive glass/film composite that senses input through voltage changes when the layers are pressed together. #### 3. Power Supply Circuitry Unlike consumer monitors that use AC power directly, the FPM-3171G is designed for industrial cabinets: * **DC-DC Converter:** Regulates the 24V DC input to the various voltages required by the logic board (5V) and the LED backlight (typically 12V or higher). * **Protection:** Includes industrial-grade surge protection and isolation to prevent damage from electrical noise common in factory floors. #### 4. Environmental Electronics * **LED Backlight Driver:** A high-efficiency driver ensures consistent brightness and a long MTBF (Mean Time Between Failures) of 50,000 hours. * **Anti-Interference:** The internal electronics are shielded to comply with **FCC Class A** and **CE** certifications, ensuring the monitor does not interfere with—or get disrupted by—nearby heavy machinery. --- ### Physical Connectivity Layout | Port Type | Function | | :--- | :--- | | **VGA Port** | Standard DB15 connector for video signal. | | **USB Port** | For touch screen data transmission. | | **RS-232** | Alternative touch screen data interface (Serial). | | **DC In** | 3-pin Phoenix terminal block for secure 24V wiring. | ---
