Product Overview

Basic Information

Manufactured in strict accordance with IEC international industrial standards, VDE specifications and B&R global quality management system, each unit undergoes full-function calibration and 72-hour continuous aging test before delivery to ensure consistent and reliable quality. The high-strength aluminum alloy and composite metal structure provides excellent mechanical strength and vibration resistance, and the overall dimensions are optimized for flush embedded installation to save cabinet internal space.

This system is equipped with a 15-inch XGA color TFT LCD display with a native resolution of 1024×768 pixels, a contrast ratio of 1000:1 and a color gamut of 16.2 million colors, presenting vivid and delicate visual effects. It adopts long-life LED backlight with a standard brightness of 450 cd/m² and low brightness attenuation. The front surface is coated with anti-glare material to reduce ambient light reflection, ensuring clear viewing under strong light or dim working environments. The horizontal and vertical viewing angles both reach 85 degrees, meeting multi-angle viewing requirements for on-site operators. The built-in industrial analog resistive touch screen supports operation with bare fingers, industrial styluses or thick protective gloves, maintaining accurate positioning and sensitive response even under strong electromagnetic interference from on-site inverters and high-power equipment. The touch panel features high scratch resistance and can withstand millions of repeated tapping operations. There are no additional physical function keys on the front frame, and all operation instructions are completed via the touch panel to adapt to space-constrained installation scenarios.

In terms of hardware configuration, the system is driven by an industrial embedded processor with stable and powerful computing performance. It is equipped with 128 MB DDR SDRAM, 2 MB Flash memory and a 256 kB battery-backed SRAM module for storing user programs, configuration parameters and historical operation data. A Type I CompactFlash expansion slot is reserved for external storage expansion, supporting flexible system upgrading and large-capacity data backup according to project requirements. The built-in hardware real-time clock is powered by a replaceable lithium backup battery, which can accurately record the timestamps of system alarms and operation logs. Independent hardware watchdog circuit and power-off protection mechanism effectively prevent system crashes and key data loss caused by program exceptions and instantaneous power failures. Multiple status LED indicators on the rear side clearly display power, operation, communication and storage working status, facilitating daily on-site inspection and maintenance.

For power supply, the rated input voltage is 24 VDC, with a wide adaptive voltage range of 18 VDC to 30 VDC to cope with common voltage fluctuations on industrial power grids. The rated operating current ranges from 0.4 A to 1.8 A. The internal circuit integrates comprehensive protection functions including overvoltage, undervoltage, overcurrent, short circuit and reverse polarity protection to protect core electronic components from damage caused by abnormal power supply. Onboard communication interfaces include one 10/100 Mbps adaptive Ethernet port, one 9-pin D-Sub RS232 serial port and two USB 2.0 Type A ports, supporting mainstream industrial communication protocols and realizing stable data interconnection with upper PLC, industrial computers, printers and mobile storage devices.

The standard package only contains the main unit of the HMI system. Wiring terminals including screw type 0TB103.9 and spring cage type 0TB103.91, shielded communication cables and installation fixtures need to be purchased separately. All programming and parameter configuration of the system are completed through the B&R Automation Studio software platform. The net weight of a single unit is approximately 6.12 kg, which is convenient for handling and installation during equipment assembly and maintenance.

Positioned as a large-sized high-definition color embedded HMI system for medium and large industrial automation systems, the 4PP320.1505-31 serves as a core human-machine interaction node in large-scale automation control networks. It can work independently as the display and operation unit of standalone large automated equipment to complete real-time process data display, full-range equipment running status monitoring, dynamic trend curve presentation and multi-level fault alarm prompting. Meanwhile, it can also be deployed as a distributed field terminal in large centralized control systems to cooperate with upper controllers for regional equipment data collection, parameter batch configuration and linkage operation management.

In terms of display performance, the 15-inch XGA high-resolution TFT screen can clearly present complex process data, equipment operating states, multi-group dynamic trend graphs and multi-interface parameter setting pages. The long-life LED backlight ensures consistent and vivid color display effects during long-term continuous operation. The anti-glare coating and wide viewing angle design meet the multi-angle viewing needs of on-site operators in different positions. The optimized display drive circuit ensures smooth screen refreshing without image lag or color distortion even in complex electromagnetic environments.

For touch operation functions, the analog resistive touch panel features fast response speed and excellent wear resistance. The built-in vibration filtering circuit effectively suppresses accidental misoperation caused by equipment shaking, ensuring reliable input when operators wear protective gloves in harsh working conditions. The full-touch operation mode simplifies the panel structure and adapts to various compact installation spaces, improving the flexibility of equipment layout.

In terms of data processing and control functions, the industrial embedded processor can run complex user programs, process multi-channel real-time data and execute medium and high-complexity logic control tasks. The equipped memory and reserved CompactFlash slot fully meet the storage and function expansion requirements of medium and large complex automation projects. Multiple hardware protection mechanisms enhance the overall system stability and reduce unplanned downtime.

In terms of communication and expansion functions, the 10/100 Mbps Ethernet port supports standard TCP/IP protocol, enabling high-speed remote online monitoring, program upload and download, and centralized production data management. The RS232 serial port can be connected with serial printers and short-distance peripheral instruments, while the dual USB ports facilitate offline program debugging and local data backup. The reserved CompactFlash slot allows users to expand storage capacity according to actual demands, realizing flexible system upgrading and large-capacity historical data storage. The standard embedded installation method simplifies assembly and disassembly procedures, and is suitable for both new automation projects and technical upgrading of old production lines. With strong compatibility, it can be matched with various on-site sensors, drives and actuators to build customized large-scale industrial control solutions.
