Basic Information
Manufactured in accordance with IEC international industrial electronic standards and B&R global quality management systems, this touch screen uses industrial-grade touch sensing layer and high-transmittance protective panel, with the outer frame made of high-strength flame-retardant engineering plastic featuring good impact resistance, corrosion resistance and anti-aging performance, adapting to long-term continuous operation at industrial sites. It is equipped with a 3-inch LCD display with a physical resolution of 160 × 80 pixels, paired with a long-life LED backlight system that provides uniform and stable brightness across the entire screen area, ensuring clear display content under different ambient brightness conditions. The touch sensing layer adopts resistive touch technology suitable for industrial scenarios, with stable sensing performance and strong adaptability, supporting accurate touch operation even when operators wear work gloves.
The touch screen is electrically connected to the main control board of the 4PP035.E300-36 host through a dedicated internal interface, realizing real-time transmission of touch signals and display signals. The rated working voltage is 24 VDC, consistent with the power supply specification of the whole terminal, and it can work normally within the voltage fluctuation range of 18 VDC to 30 VDC. The internal drive circuit integrates overvoltage, undervoltage, overcurrent and short-circuit protection functions to avoid touch failure or component damage caused by power supply anomalies. Before leaving the factory, every finished touch screen undergoes strict tests including touch accuracy test, response speed test, display uniformity test, brightness calibration and long-term aging test to ensure consistent quality of each product. This model is classified as an obsolete legacy product of B&R, and related supply and maintenance services are still available through official channels.
Function and Positioning
Positioned as the dedicated touch interaction and display component for the B&R 4PP035.E300-36 integrated HMI terminal, this touch screen undertakes core visual display and touch operation tasks, and works together with the supporting 26-key membrane keypad to build a comprehensive human-machine interaction system.
In terms of information display, the 3-inch LCD screen can clearly present equipment operating parameters, real-time process status, set values, running indicators, fault alarm codes and system prompt information. The high-precision pixel design ensures that characters and simple graphics are displayed without distortion or blur, facilitating operators to quickly read and judge equipment operating conditions. The LED backlight maintains stable brightness in both dim workshop environments and strong light conditions, ensuring that display content is always readable.
In terms of touch operation, the resistive touch layer features fast response speed and high positioning accuracy, supporting single-point touch for parameter modification, page switching, function selection and equipment start-stop control. Each touch action can generate synchronous signal feedback, and the display content updates in real time along with the operation, effectively reducing the risk of misoperation. The touch screen supports multi-angle conventional operation, and can still maintain stable sensing performance under slight vibration environments. As a replaceable maintenance component of the integrated terminal, it features a standardized assembly structure, which allows for quick disassembly and on-site replacement during equipment maintenance, effectively shortening production downtime. It can meet the operation and display requirements of small and medium-sized standalone equipment, and also serve as a local interaction node in large-scale distributed production lines to cooperate with the central control system to complete partitioned equipment monitoring and operation.
Core Performance Parameters
Regarding display performance, the touch screen is equipped with a 3-inch LCD panel with a resolution of 160 × 80 pixels, delivering clear character and graphic display effects. The LED backlight provides even brightness across the whole screen with no dark areas or color cast after long-term operation. The liquid crystal panel has a fast response speed, and the display content can be updated synchronously with system data without lag or ghosting. The viewing angle conforms to industrial application standards, enabling normal viewing from multiple conventional operation directions.
For touch performance, the resistive touch sensing layer has a long service life, supporting a large number of repeated touches. It has moderate sensing force and fast response time, ensuring accurate and sensitive touch operation. The touch surface is equipped with a wear-resistant and anti-scratch protective layer, which can resist daily friction and accidental scratches at industrial sites and extend the service life.
In terms of electrical performance, the rated working voltage is 24 VDC, with an allowable voltage fluctuation range of 18 VDC to 30 VDC. The power consumption is low, which will not increase the overall energy consumption of the terminal. The internal circuit has complete electrical protection mechanisms to resist instantaneous voltage surges and current impacts. The signal transmission interface adopts shielding and anti-interference design, which can effectively suppress electromagnetic interference from surrounding motors and frequency converters, ensuring stable transmission of touch signals and display signals.
For environmental adaptability, the touch screen can operate normally within an ambient temperature range of 0°C to +50°C, and the storage temperature ranges from -20°C to +60°C. It can withstand ambient relative humidity of 10% to 90% under non-condensing conditions, with good moisture-proof and mildew-proof capabilities. The whole module passes industrial standard vibration and impact tests; the touch function and display content will not flicker or malfunction when subjected to mechanical vibration from operating equipment. The internal circuit boards are coated with conformal coating to enhance anti-corrosion and anti-aging performance, adapting to long-term use in complex industrial environments.
General Matching Accessories
For installation and replacement, the touch screen is matched with dedicated sealing gaskets and fixing fasteners. The sealing gaskets ensure the sealing performance between the touch screen and the terminal front panel, maintaining the IP65 protection level. The fixing fasteners are designed for easy disassembly and assembly, facilitating quick on-site replacement during maintenance. Professional disassembly tools are recommended during replacement to avoid scratching the touch surface or damaging internal wiring.
In terms of electrical connection, the touch screen uses original dedicated signal cables and power cables that match the 4PP035.E300-36 host. These cables have excellent shielding performance, which can reduce external electromagnetic interference and ensure stable signal and power transmission. Damaged cables must be replaced with original or fully compatible cables to avoid touch failure or display abnormality caused by poor contact or signal distortion.
For daily maintenance, clean soft cloths and neutral cleaning agents are supporting supplies. It is strictly prohibited to use corrosive liquids, sharp tools or hard objects to wipe the touch surface, so as not to damage the touch sensing layer and protective film. Spare touch screen modules of the same model can be stored as maintenance spare parts, and all spare parts need to be stored in a dry, dust-free environment within the specified temperature range. All supporting accessories and spare parts comply with B&R unified industrial standards, featuring high versatility and easy procurement. It should be noted that 2 pieces of TB718 terminal blocks and 1 piece of TB103 terminal block required for the whole terminal need to be ordered separately.
