Product Description:

The B & R Automation 4PP220.0571-K23 Power Panel is a compact, reliable operator interface constructed for easy integration, accurate control, and economical monitoring in multiple automation systems. This power panel is fitted with a 5.7-inch (144 mm) monochrome LCD display that has 8 shades of gray to provide clear and effective visual indications.

This 4PP220.0571-K23 Power Panel has a rated voltage of 24 VDC ±25% to ensure compatibility across a broad spectrum of industrial power supplies. This panel’s nominal power consumption is 12 W, and the maximum power consumption is 17 W to demonstrate effective energy efficiency under both normal and extreme usage. The startup current of this power panel is capped at 20 A for less than 1 ms to save components from damage when initially powered up and ease loading on connected power supplies. One important control feature of this panel is its easily accessible reset button that enables operators or technicians to execute manual resets without having access to the inner circuitry. This panel also comes equipped with two LED indicators: a user-configurable green LED and a yellow CF LED for CompactFlash operations, which helps in system diagnostics and monitoring data storage.

The operating ambient temperature range of this power panel is 0 to +50 °C to facilitate consistent operation in standard industrial conditions. This 4PP220.0571-K23 Power Panel further accommodates an operational height of up to 3000 meters for providing stability in high-rise installations without loss in performance. For increased safety and reliability, this power panel is built with electrical isolation, which protects internal and external systems from voltage spikes or ground loops. Additionally, this panel has a bleeder resistance of ≥ 47 kOhm, which ensures safe discharge of residual voltages on shutdown, further enhancing the overall safety during maintenance activities.

Frequently Asked Questions about 4PP220.0571-K23:

Q: How does the 8-shade grayscale benefit the LCD in 4PP220.0571-K23?

A: It offers basic visual contrast for essential graphical elements and text. This allows for simplified visualization without color processing load.

Q: Why is electrical isolation important in the Power Panel 4PP220.0571-K23?

A: It prevents ground loop issues and protects internal circuits from external voltage surges. This improves device longevity in harsh environments.

Q: What is the function of the yellow CF LED on 4PP220.0571-K23?

A: It indicates CompactFlash card activity, helping in monitoring read/write operations. This assists in storage diagnostics during runtime.

Q: Why is the reset button externally accessible on this Power Panel?

A: It allows quick system reboots without opening enclosures. This reduces downtime during maintenance or troubleshooting.

Q: How does the short 20 A inrush current in 4PP220.0571-K23 affect power design?

A: It demands fast-responding power supplies but prevents extended load peaks. This reduces the risk of tripping breakers at startup.
