Basic Information
Manufactured in accordance with IEC international industrial electronic standards and B&R global quality management systems, this controller uses industrial-grade resistive touch sensing layer, high-stability main control chips and anti-aging circuit components, with the outer frame made of high-strength flame-retardant engineering plastic that features good impact resistance, corrosion resistance and anti-aging properties. It is equipped with a 3-inch LCD display with a physical resolution of 160 × 80 pixels, matched with a long-life LED backlight module to ensure clear display under different ambient brightness. The resistive touch layer supports accurate operation even when operators wear work gloves, with stable sensing performance and strong environmental adaptability.
The controller is powered by 24 VDC, allowing a voltage fluctuation range of 18 VDC to 30 VDC, and the built-in circuit integrates overvoltage, undervoltage, overcurrent and short-circuit protection functions to avoid component damage caused by power supply anomalies. It connects with the terminal’s mainboard through dedicated internal interfaces to complete real-time transmission of touch signals, display signals and control signals. Before delivery, each unit undergoes strict tests including touch accuracy test, response speed test, signal stability test and 72-hour continuous aging test to ensure consistent quality. This model is a legacy product of B&R, and relevant supply and technical support services are still available through official channels.
Function and Positioning
Positioned as the core control and interaction component of the 4PP035.E300-36 integrated HMI terminal, this touch screen controller undertakes three core tasks: touch signal acquisition and processing, display content driving and output, and linkage control with the system and peripheral keys. As an independent functional control subsystem inside the terminal, it cooperates with the host control unit, display system and membrane keypad to build a complete industrial human-machine interaction system.
In terms of touch control, the controller collects touch coordinates and action signals in real time, and converts them into standard control instructions after internal algorithm processing, so as to realize functions such as parameter modification, page switching, function selection and equipment start-stop control. It features fast signal response and high positioning accuracy, and can effectively filter interference signals generated by slight vibration to reduce misoperation risks. In terms of display control, it receives data instructions from the main system and drives the LCD screen to display equipment operating parameters, process status, alarm codes and system prompts, ensuring synchronous update of display content and operating actions. In terms of system linkage, it realizes signal interaction with the 26-key membrane keypad, supports combined operation of touch and physical keys, and uploads on-site operation data and equipment status information to the upper control system through the internal bus.
Adopting a modular design, the controller can be quickly disassembled and replaced during equipment maintenance, which helps shorten production downtime. It can meet the control and interaction requirements of small and medium-sized standalone automated equipment, and also serve as a local control node in large-scale distributed production lines to cooperate with the central control system to complete partitioned equipment monitoring and operation.
Core Performance Parameters
For touch control performance, the built-in resistive touch unit has a long service life and supports millions of repeated touches. The touch response time is short, with moderate sensing force, and the positioning error is controlled within the industrial standard range to ensure accurate and sensitive operation. The touch surface is equipped with a wear-resistant and scratch-proof protective layer to adapt to long-term use in industrial sites. The internal signal processing circuit has strong anti-interference ability, which can suppress electromagnetic interference from surrounding motors and frequency converters and ensure stable transmission of touch signals.
In terms of display driving performance, the controller supports a 3-inch 160 × 80 pixel LCD screen, which can drive the screen to output uniform and stable images and characters without distortion, blur or ghosting. It adjusts the brightness of the LED backlight dynamically according to ambient brightness, maintaining good visibility in both dim and strong light environments. The display refresh rate matches the system data update speed, realizing synchronous display of data.
Regarding electrical performance, the rated working voltage is 24 VDC, with an allowable voltage range of 18 VDC to 30 VDC and low overall power consumption. The internal circuit has complete electrical protection mechanisms to resist instantaneous voltage surges and current impacts. The signal interface adopts shielding design to further enhance anti-interference capability.
In terms of environmental adaptability, the controller can work normally at an ambient temperature of 0°C to +50°C, and the storage temperature ranges from -20°C to +60°C. It can withstand a relative humidity of 10% to 90% (non-condensing), with good moisture-proof and mildew-proof performance. The whole machine passes industrial vibration and impact tests, and the touch and display functions will not fail when subjected to mechanical vibration. The internal circuit boards are coated with conformal coating to enhance corrosion resistance and aging resistance.
General Matching Accessories
For installation and replacement, the controller is equipped with dedicated sealing gaskets and fixing fasteners. The sealing gaskets ensure the sealing between the controller and the terminal front panel, maintaining the IP65 protection level. The fasteners are designed for easy disassembly and assembly, facilitating quick on-site replacement. It is recommended to use professional disassembly tools during replacement to avoid scratching the touch surface or damaging internal wiring.
In terms of electrical connection, supporting original dedicated signal cables and power cables are provided. These cables have excellent shielding performance, which can reduce external electromagnetic interference and ensure stable transmission of power and signals. Damaged cables must be replaced with original or fully compatible cables to avoid signal distortion or poor contact faults.
For daily maintenance, supporting supplies include clean soft cloths and neutral cleaning agents. It is forbidden 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 controllers of the same model can be stored as maintenance parts, which need to be placed in a dry and dust-free environment within the specified temperature range. All accessories and spare parts comply with B&R unified industrial standards, featuring high versatility and easy procurement. It should be noted that TB718 and TB103 terminal blocks required for the complete terminal need to be ordered separately.
