Product Description:
The 4PP250.0571-K19 4PP Power Panel provides a balanced combination of durability, communication ability, and energy efficiency for various demanding automation applications. The front of this panel is rated at protection level IP65 / NEMA 250 Type 4X, which keeps it dust-tight, watertight, and resistant.
The 4PP250.0571-K19 4PP relies on a Geode SC2200 graphics controller, which ensures stable display output for embedded operations. The onboard Renata 950 mAh battery provides real-time clock and memory backup capabilities with the ability to save system states during power failure. The communication interfaces of this panel are supported by a serial COM interface having transfer rates up to 115 kBaud, to enable legacy PLC and field device integration. This panel also has a USB interface with data transfer capabilities of 1.5 Mbit/s (low speed) and 12 Mbit/s (full speed), to permit efficient peripheral connection and firmware upgrading. The power efficiency of this panel is ensured with a nominal power consumption of 17 W, and its design features a bleeder resistance of ≥ 47 kOhm to discharge residual voltage safely. This power panel is capable of withstanding mechanical stress with a shock resistance rating of 15 g for 11 ms.
The rear side of this panel has IP20 protection, appropriate for protected or enclosed installation. This power panel is capable of operating reliably in environments with relative humidity from 5% to 85% (non-condensing). This panel’s holding torque for an aPCI module reaches a maximum value of 0.7 Nm to ensure safe module attachment. In terms of memory, the 4PP250.0571-K19 panel is equipped with 64 MB SDRAM for transient memory operations. For data retention and system settings storage, this panel has 256 kB of non-volatile SRAM, which is suitable for small-to-medium-sized HMI applications requiring consistency and fast boot times.
