4PP420.0571-K14 by B & R Automation

The 4PP420.0571-K14 operator terminal is a compact Power Panel built by B&R Automation within the 4PP Power Panels series. As an integrated HMI and control node, it combines visualization, user input, and PLC-level logic to drive machine sequences from a single enclosure. Deployed on control cabinets or swing arms, it streamlines industrial automation by removing the need for separate PCs and touch displays while still exposing fieldbus and Ethernet channels for supervisory links.

Its processing core is a 500 MHz AMD Geode LX800 processor that executes real-time tasks and user interface routines without an additional coprocessor. The CPU is paired with 128 MB of SDRAM, providing run-time space for the B&R Automation Runtime and application variables, while 512 kB of battery-backed SRAM retains machine recipes during power loss. Passive heat dissipation through an aluminum heat sink eliminates moving parts, and the bleeder resistance is 0 ?. Network communication is supported through a 10/100 Mbit/s Ethernet interface for programming or SCADA links, and the sealed front meets IP65 so it withstands sprayed water and airborne dust in washdown areas. Normal operation draws 0.5 A from the 24 V rail, matching typical cabinet power budgets.

Visualization is handled by a 5.7 in transmissive LCD with a 320 × 240 (QVGA) active area, driven by an Elo 12-bit controller for accurate analog positioning across the resistive grid. The screen responds to finger or stylus pressure thanks to the analog resistive touch layer, allowing use with gloved hands on packaging lines. Control electronics accept 18 to 30 VDC so the panel tolerates common fluctuations on unregulated 24 V supplies. Physical dimensions of 212 × 156 × 76 mm permit shallow mounting, and the passive design keeps acoustic noise at zero.
