Product Description:
The B & R Automation 's 4PP045.0571-K55 is a compact operator panel. The series to which this panel belongs is 4PP Power Panels. It offers industrial-grade features with space-saving construction. It combines display, controller and interface in one unit. It is designed for use in harsh automation environments.
The 4PP045.0571-K55 features a 5.7-inch color display. It supports 320x240 QVGA resolution with 700:1 contrast and 400 cd/m^2 brightness. The analog touchscreen ensures precise input. Viewing angles reach 80 degrees in all directions. Its backlight operates up to 50,000 hours. The AMD Geode LX800 processor of panel runs at 500 MHz frequency. It integrates 128 MB DDR SDRAM and 232 kB non-volatile SRAM. For remanent variables 32 kB memory is available. Firmware is stored on 4 MB internal Flash. The unit includes a battery-backed real-time clock. It also features watchdog and MTCX bootloader support. Electrical input requires 24 VDC ~25% supply. Typical power consumption is 10 W with 0.45 A nominal current. Maximum inrush current is 2.8 A. The panel is 203 mm in length; 145 mm height and 56.5 mm. Front protection rating is IP65 and NEMA Type 4X. Rear is rated IP20 with CompactFlash card inserted. Operating temperature is 0 to 50 degrees C. Storage is supported from -20 to 70 degrees C. It withstands 15g shocks and up to 0.5 g vibrations.
The 4PP045.0571-K55 includes Ethernet 10/100 Base-T on RJ45. Two USB 2.0 ports (Type A) are provided with 500 mA max each. A CompactFlash Type I slot is i for IDE storage. It offers one interface expansion slot for CAN or PROFIBUS. Variants support either POWERLINK or X2X Link for communication. The Power Panels are CE, UL, EAC and KC certified. Humidity tolerance ranges from 10 to 90% non-condensing. The module is engineered for demanding industrial control systems.
Frequently Asked Questions about 4PP045.0571-K55:
Q: What is the purpose of the MTCX bootloader in 4PP045.0571-K55?
A: The Maintenance Controller Extended (MTCX) ensures secure startup and system recovery. It helps maintain operational integrity during power failures or firmware issues.
Q: How does the 232 kB non-volatile SRAM benefit the system?
A: It retains data without requiring constant power. This supports critical application values and system states in power-off scenarios.
Q: Why is a battery-backed real-time clock important in 4PP045.0571-K55?
A: It maintains accurate timekeeping during power loss. This is essential for time-stamping events and scheduling in automation processes.
Q: Can the CompactFlash slot in 4PP045.0571-K55 be hot-swapped during operation?
A: No, the CompactFlash slot is not designed for hot-swap use. Power must be turned off to safely insert or remove cards.
Q: How does the absence of galvanic isolation affect system design with 4PP045.0571-K55?
A: System designers must ensure electrical separation where needed. This impacts how the panel interfaces with sensitive external equipment.
