Basic Information
All units are manufactured per IEC international industrial standards and B&R global quality control specifications. Every finished product undergoes screen color calibration, touch precision verification, keypad function testing and continuous 72-hour burn-in aging inspection before factory delivery to guarantee consistent operational reliability. The outer casing is constructed with high-strength reinforced engineering plastic and metal inner frame, delivering outstanding shock resistance and structural durability for long-term field usage. Compact overall dimension enables side-by-side nested installation inside limited cabinet space, with single unit net weight around 1.5kg for easy field mounting and replacement during equipment maintenance.
This system is configured with a 5.7-inch QVGA color TFT LCD featuring conventional CCFL backlight, native resolution at 320×240 pixels and up to 262,144 available display colors. It delivers 350:1 nominal contrast ratio with standardized industrial viewing angles to satisfy multi-angle viewing requirements for field operators. Anti-glare coating is applied on the outer screen surface to cut down ambient light reflection, ensuring legible color display under intense workshop illumination or dim production environments. The built-in industrial analog resistive touch panel supports input via bare fingers, industrial stylus tools and thick insulated work gloves, retaining accurate positioning and rapid response even under EMI disturbance from on-site inverters and high-power motors. Physical power switch, reset button and configurable DIP operating switches are pre-installed on the front panel to expand manual operation options matching diversified on-site application habits.
For internal hardware layout, the unit runs on AMD Geode LX800 500MHz industrial x86 processor, paired with 128MB DDR SDRAM, 2MB onboard Flash memory, 512kB battery-backed SRAM and dedicated non-volatile storage for persistent variable data. A Type-I CompactFlash slot and single aPCI expansion slot are reserved for external storage expansion and function module upgrade according to project customization needs. Internal hardware real-time clock is powered by replaceable Renata lithium battery with around 3-year service lifespan, precisely marking timestamp for system fault logs and operation records. Independent hardware watchdog circuit plus instantaneous power-off protection prevents system halt and core configuration data loss triggered by program exceptions or sudden power fluctuation. Multiple LED indicator lamps on the rear side intuitively reflect power status, running state, communication link and system fault information to simplify daily routine inspection work.
Regarding power specification, rated input is 24VDC with wide working voltage tolerance spanning 18VDC to 30VDC to adapt unstable voltage fluctuation of industrial power supply networks. Built-in power management circuit integrates overvoltage, undervoltage, overcurrent, short-circuit and reverse connection protection to shield core electronic components from abnormal power damage. Standard onboard communication interfaces include one 10/100Mbps RJ45 Ethernet port, one 9Pin RS232 D-Sub serial interface and dual USB2.0 Type-A ports, compatible with mainstream industrial communication protocols to achieve seamless data connection with external PLC systems, industrial PCs, serial printers and mobile storage devices. Entire program editing, parameter configuration and system debugging are accomplished via B&R Automation Studio programming software.
Original standard packing only includes the HMI system main body. Wiring terminal blocks, power supply cables, communication wires and installation fasteners are not contained in original package and must be ordered separately. Matching terminal options cover 0TB103.9 screw-type terminals and 0TB103.91 spring cage terminals, mutually interchangeable to fit different field wiring practices.
Function and Positioning
Positioned as compact all-in-one control and visualization system for small and mid-size automated equipment, 4PP451.0571-75 acts as integrated HMI and lightweight local control node within distributed automation architectures. It can work independently as core control and operation terminal for standalone small automated machines, completing real-time colorful process curve display, full equipment operational status tracking, batch parameter adjustment and tiered fault alert pop-up. Meanwhile, it can be deployed as field branch terminal within large-scale centralized control networks, cooperating with superior main controllers to finish local data collection, on-site manual operation and regional equipment remote monitoring for segmented production lines.
On display function aspect, the QVGA high-color TFT screen renders vivid process flow diagrams, real-time numerical data, dynamic trend curves and parameter setup interfaces with authentic color restoration. Long-service CCFL backlight maintains steady brightness under prolonged nonstop running, while anti-glare surface and optimized viewing angle eliminate blurred display caused by varied ambient light. Optimized display drive circuitry ensures smooth screen refresh without frame lag, color cast or screen flicker even under complex electromagnetic field surroundings.
Touch operation function leverages industrial resistive touch technology featuring fast response and robust anti-shock capability. Embedded anti-shake filter circuit effectively eliminates false touch input induced by equipment mechanical vibration, enabling stable glove operation under harsh workshop conditions. Combined with physical panel switches and mode dial switches, dual-operation design improves operational flexibility to satisfy high-frequency frequent operation and special site application requirements.
