4PP055.0571-K30 B&R

Product Dimensions：

The 4PP055.0571-K30 is a 5.7-inch QVGA color display unit featuring a resistive touchscreen. It serves as a dual-function device, acting as both the operator interface and the central controller for a machine. It is powered by an X86-compatible processor, allowing it to run B&R’s Automation Studio software. This integration ensures that logic control and visualization are perfectly synchronized, as they share the same hardware resources. The "K30" designation often refers to a specific configuration of memory or communication interfaces tailored for industrial standard applications, typically featuring an aluminum front with an IP65 protection rating.

Product Parameters

• Display Size: 5.7 inch diagonal

• Resolution: $320 \times 240$ pixels (QVGA)

• Display Type: TFT Color with 256 colors

• Processor: Geode LX800 or equivalent low-power X86 processor

• Memory: Typically equipped with $128 \text{ MB}$ or $256 \text{ MB}$ of RAM and internal CompactFlash slot for storage

• Input Voltage: $24 \text{ VDC}$ (nominal range $18$ to $30 \text{ VDC}$)

• Interfaces: Features $1 \times$ RS-232, $2 \times$ USB 2.0 ports, and $1 \times$ Fast Ethernet ($10/100 \text{ Mbit/s}$)

• Expansion: Supports X2X Link or specialized fieldbus modules for remote I/O expansion

• Protection: IP65 on the front (when installed in a control cabinet) and IP20 on the back

Product Advantages

A major advantage of the 4PP055.0571-K30 is its Cost-Effectiveness. By combining the PLC and HMI into a single housing, users reduce the cost of purchasing separate components and minimize the wiring effort between them. The Fanless Design is another significant benefit; because the unit does not rely on moving parts for cooling, it is less prone to failure in dusty environments and requires zero maintenance.

The Integrated Communication options allow the Power Panel to act as a data gateway, collecting information from the field via X2X Link and transmitting it to higher-level systems via Ethernet. Furthermore, the use of Automation Studio provides a unified engineering environment, meaning programmers only need one software tool to develop both the control logic and the graphical user interface.

Important Considerations and Precautions

When installing the 4PP055.0571-K30, you must ensure Proper Cabinet Mounting to maintain its IP65 rating; any gaps in the seal can allow moisture or oil to penetrate the electronics. Regarding Data Storage, always use industrial-grade CompactFlash cards recommended by B&R, as standard consumer cards may fail prematurely due to high write cycles.

A critical precaution involves Power Supply Stability; while the unit can handle a range of DC voltages, sudden drops or spikes can cause the OS to crash or corrupt the application memory if the unit is in the middle of a write operation. It is also important to note that the Resistive Touchscreen should be operated with fingers or specialized styluses only; sharp objects like screwdrivers can puncture the outer layer, leading to permanent touch failure. Finally, because this model is part of a legacy series, users should verify the Availability of Spare Parts or consider migration paths for long-term machine life cycles.

Product Applications

The B&R 4PP055.0571-K30 is commonly found in decentralized automation tasks across various industries.

• Food and Beverage Packaging: Controlling small labeling machines, flow-wrappers, or filling stations where space is limited.

• Plastic Processing: Monitoring and controlling auxiliary equipment like dryers, chillers, or material transport systems.

• Building Automation: Serving as a central control and visualization point for HVAC systems or industrial lighting arrays.

• Standard Machinery: Used by machine builders (OEMs) for compact textile machines, wood-processing saws, and metal-forming presses.

• Environmental Technology: Monitoring water treatment parameters or solar array tracking systems where remote data logging via Ethernet is required.
