The **ST6200T-R** is a specialized high-performance industrial touch terminal, typically associated with the **Pro-face (Schneider Electric)** ST6000 series. This device is designed for Human-Machine Interface (HMI) applications, acting as a bridge between operators and industrial machinery. Below is a breakdown of its core electronic and technical components. ### 1. Core Technical Specifications The ST6200T-R is built with industrial-grade silicon designed for 24/7 operation in harsh environments. | Feature | Specification | | :--- | :--- | | **Display Type** | 10.1" Wide TFT Color LCD | | **Resolution** | 1024 x 600 pixels (WSVGA) | | **Touch Panel** | Resistive Film (Analog) - often denoted by the "R" suffix | | **Processor** | ARM Cortex-A9 Single Core (800 MHz) | | **Memory** | 512 MB Device Memory / 128 KB Backup Memory (NVRAM) | | **Input Voltage** | 24 VDC | --- ### 2. Electronic Connectivity & Interfaces The board layout includes several integrated communication controllers to interface with Programmable Logic Controllers (PLCs). * **Serial Ports (COM1/COM2):** * **COM1:** RS-232C (D-Sub 9-pin). * **COM2:** RS-422/485 (D-Sub 9-pin). * **Ethernet Port:** 10/100 Base-T (RJ-45) for networking and IoT integration. * **USB Interfaces:** * **USB 2.0 Type A:** For data storage (USB sticks) or peripherals like barcode scanners. * **USB 2.0 Micro-B:** Dedicated for PC-to-HMI programming transfers. --- ### 3. Display & Touch Electronics The "R" in the model name highlights the **Resistive Touch** technology, which differs electronically from the capacitive screens found on smartphones: 1. **Resistive Layers:** Two flexible layers coated with a resistive material (Indium Tin Oxide) separated by an air gap. 2. **Voltage Gradient:** When pressed, the layers touch, creating a voltage drop detected by the internal Analog-to-Digital Converter (ADC). 3. **Benefit:** It allows operation with gloves, styluses, or in environments with heavy electrical noise/moisture where capacitive screens would fail. --- ### 4. Power Circuitry The device features an internal DC-DC converter to manage industrial power fluctuations. ```yaml Power_System: Input_Rating: 24V DC (Range: 19.2 to 28.8 VDC) Power_Consumption: 12.5W or less Isolation: Integrated isolation between power and internal circuits to prevent ground loops. Battery: Internal lithium battery for clock and backup memory data retention. ``` --- ### 5. Environmental Hardening The electronic housing is designed to meet **IP65F** standards. * **Circuit Coating:** Often features conformal coating to prevent corrosion from humidity. * **Backlight:** Uses white LED backlighting with a service life of approximately 50,000 hours.
