4PP420.0571-K49
The 4PP420.0571-K49 power panel from B & R Automation is an integral component of the 4PP Power Panels series designed for industrial automation and human-machine interface applications. This compact control surface features a 5.7-inch TFT display with an analog resistive touchscreen that provides intuitive operation under harsh conditions. The panel delivers a crisp QVGA presentation at 320 x 240 pixels, 25:1 contrast ratio, ensuring clear visualization of process parameters and alarms. Powered by an Intel Atom processor and equipped with 256 MB RAM, the unit balances computational efficiency with low power consumption. Front-side protection conforms to IP65 / NEMA 250 type 4X, guaranteeing complete dust sealing and defense against sprayed water.
Performance and technical connectivity are optimized through multiple standardized interfaces. The panel integrates an Intel 82551ER Ethernet controller for high-speed network communication and seamless integration with SCADA or PLC systems. Legacy device compatibility is assured by a serial interface type: RS232, modem-capable link, enabling direct connection to printers, barcode scanners, or data loggers. Two USB interfaces facilitate data transfer, firmware updates, and the attachment of external storage or input peripherals. System reliability is bolstered by electrical isolation on all I/O channels, minimizing interference and protecting against ground loops. An externally accessible reset button provides rapid recovery and simplifies maintenance during commissioning or troubleshooting.
Designed for uninterrupted operation, the panel incorporates a backup capacitor with a 10-minute buffer time to preserve volatile memory during battery replacement or unexpected power loss. Local program storage is handled via a Type I compact flash slot, offering fast boot times and firmware redundancy. The device’s ambient transport range of –20 to +70 °C ensures resilience during shipping and staging, while its operational IP65 rating makes it suitable for washdown environments. Integration into existing control architectures is straightforward, with flexible mounting options and standardized communication protocols. The 4PP420.0571-K49 excels in applications such as machine control, packaging lines, and process monitoring where reliability, clear visualization, and robust connectivity are paramount.
