Product Description:
The 4PP420.0571-K49 Power Panel is a small, industrial-strength control panel that provides efficient human-machine interaction and trouble-free connectivity. Made by B & R Automation, this panel accommodates a QVGA-resolution screen measuring 320 x 240 pixels with a 25:1 contrast ratio, supplying crisp and clear visual output.
This panel’s front retains an IP65 / NEMA 250 type 4X level of protection rating, which offers full dustproofing from dust ingress and sprayed water and is best for washdown environments. The 4PP420.0571-K49 power panel can be integrated with external peripherals like storage devices, scanners, or input devices through 2 USB interfaces. In case of serial communication, this panel provides a modem-capable RS232 interface for interfacing legacy systems and serial devices that are predominantly used in industrial automation. This panel also comes with an Intel 82551ER Ethernet controller for high-speed, consistent network communication, enabling integration with factory networks and control systems. The power supply rated current of the 4PP420.0571-K49 panel is a maximum of 1.2 A for effective power utilization with stable device operation. To make this panel more convenient, there is an externally accessible reset button for instant reboot without requiring panel opening.
For internal memory assistance, this 4PP420.0571-K49 panel features a Type I compact flash interface to enable local program storage capability and quick system boot times. An internal backup capacitor of this panel offers a 10-minute battery replacement buffer time with data retention, thus avoiding loss of memory during power failure. This panel is also designed with electrical isolation, which protects against electrical faults and minimizes signal interference risk. This panel’s durability in the environment is guaranteed through an ambient transport temperature range of -20 to +70 °C, which allows secure transportation and storage under different conditions.
