Product Description:
B&R 4pp420.0571-k28 Power Panel offers efficient performance with shared graphics memory, smart power loss management via an onboard SMC and dependable Ethernet connectivity at 10/100 Mbps. This module is built for stable industrial integration as it supports essential visual tasks and ensures data integrity during power interruptions and seamless communication with control systems.
The 4pp420.0571-k28 power panel supports two levels of USB data transmission, one that handles slower, basic input devices like a keyboard or mouse and another that allows for moderate-speed data exchanges. This module display offers a relatively modest level of visual clarity, suitable for simple user interfaces, menu navigation or basic graphical representation and the protective surface over the touch display is manufactured from polyester, which is a tough, flexible plastic which resists abrasion and some chemicals. The panel can absorb sudden jolts or shocks up to 15 times gravity such as drops or physical impacts without malfunctioning at least for short durations up to 11 milliseconds which makes the panel resilient in environments where mechanical vibration or bumps are common. It features a legacy communication interface that uses a 9-pin male connector, typically employed for RS-232 or RS-485 protocols which allows for straightforward connections to other industrial devices or controllers still relying on traditional serial communication.
This 4pp420.0571-k28 power panel screen reacts to physical pressure from a finger, stylus or gloved hand by using a resistive mechanism, rather than detecting capacitance and this module can tolerate continuous low-frequency shaking from 2–9 Hz with 1.75 mm sway and higher-frequency movement from 9–200 Hz at 0.5 g acceleration. Its screen built-in lighting system emits 150 candelas per square meter which is appropriate for indoor use and environments with moderate ambient light.
Frequently Asked Questions about 4pp420.0571-k28:
Q: How does the polyester overlay help in industrial environments?
A: The polyester overlay resists abrasions, chemicals, and wear from repeated touches. This extends screen lifespan in tough factory or machine environments.
Q: Why does the 4pp420.0571-k28 use a resistive touchscreen instead of a capacitive one?
A: Resistive touchscreens allow operation with gloves or stylus, common in industrial settings. This suits harsh environments where bare finger input isn't always feasible.
Q: How does the 4 MB shared graphics memory impact display performance?
A: While limited in graphics power, it efficiently supports HMI elements like buttons and indicators. This helps reduce cost while maintaining essential visual functionality.
Q: What are the advantages of having a 9-pin DSUB connector in 4pp420.0571-k28?
A: The DSUB serial port ensures compatibility with legacy industrial systems. It's useful in retrofits or communication with older PLCs and sensors.
Q: Can 4pp420.0571-k28 Power Panel handle continuous machine vibration?
A: Yes, it withstands frequency ranges from 2–200 Hz with specific amplitude and acceleration thresholds. This makes it dependable in vibrating machinery environments.
