Product Description:
The 4PPC70.0702-20B is a power panel that Beckhoff made for tasks like embedded control and visualization. It has a 7.0-inch color TFT screen that can display 800 x 480 pixels. The panel has an analog resistive touchscreen set up in horizontal mode. There are dark gray pinstripes on the front panel.
The 4PPC70.0702-20B power panel is supported by an Intel Atom E620T processor running at 333 MHz. It has 256 MB DDRAM for immediate file working. Programs are embedded within a 2 GB eMMC flash memory for safe and reliable use. The panel also has an inbuilt alarm that detects any fault and raises an alarm. If necessary, hardware can be manually set using a specific reset switch. The board does not have any fans, so it has a passive cooling system. So, it is easy to support and runs more smoothly. Such a design allows the system to always operate and provides ease of integration in embedded control systems where uptimes are to be made reliable and where there is proper thermal management. The power panel does not contain a CompactFlash slot, therefore, it contains fewer operational components.
The 4PPC70.0702-20B power panel has a 32 kB FRAM that keeps important system files safe. It has a real-time clock that is accurate to one second and has a backup of about 1000 hours. The quickest task cycle is 1 ms, and the slowest time that can be reached is 0.4 ms. In the event of a power outage, the memory design ensures that the system configurations are retained and remain unchanged. The power panel functions effectively in small embedded control settings that prioritize dependability and timing.
Frequently Asked Questions about 4PPC70.0702-20B:
Q: Why does 4PPC70.0702-20B use passive cooling?
A: Passive cooling removes moving parts, which lowers noise and improves long-term durability without reducing heat dissipation.
Q: Why is the task cycle in 4PPC70.0702-20B important?
A: A 1 ms task cycle supports precise control logic execution and is ideal for time-sensitive automation processes.
Q: Does 4PPC70.0702-20B support a touch input interface?
A: Yes, it includes an analog resistive touchscreen that allows accurate finger and stylus interaction in control operations.
Q: Do 4PPC70.0702-20B systems include FRAM?
A: Yes, it includes 32 kB FRAM that ensures retention of critical remanent data during power-off cycles.
Q: How does the buzzer help in 4PPC70.0702-20B?
A: The buzzer gives immediate audible feedback that supports diagnostics and alert mechanisms in control tasks.
