Product Description:

The 4PP035.E300-K12 operator panel is produced by B&R Automation as part of the 4PP Power Panels series. It serves as a compact human-machine interface for small machines and auxiliary stations, providing process feedback on a monochrome LCD while sending keypad commands to the controller through built-in CAN and RS232 ports. Its role in industrial automation is to simplify on-site parameter entry, alarm acknowledgment, and basic diagnostics without the need for a full PC-based terminal. This makes it suitable for stations where local control input and quick status viewing are more important than complex visualization.

The display measures 3 in diagonally and renders graphics at 160 x 80 pixels, a resolution suited to text menus and simple trend lines. An LED backlight keeps the screen readable across the rated ambient range and avoids the lamp type used in older CCFL designs. System electronics draw from a single 24 VDC supply, keeping wiring in line with common control-cabinet power buses, and total demand stays under 6 W so heat buildup inside enclosures is minimal. Operation is maintained between 0 to 50 °C under standard factory conditions, while storage is permissible down to −20 °C without display damage. The housing spans 153 mm in width and 120 mm in height, allowing installation in tight operator stations where panel space is limited.

The front foil, keypad matrix, and gasket earn an ingress rating of IP65, helping protect the machine front against dust and low-pressure water exposure. Fieldbus traffic moves over a single CAN node at 500 kbit/s, giving deterministic updates for setpoints and status bits during routine operation. Recipe transfers or service diagnostics can be handled on the RS232 port operating at 115.2 kbit/s. User interaction relies on 26 keys, combining numeric, navigation, and soft-function buttons so operators can move through menus without an external pointing device.
