Product Description:

The 6PPT30.057L-20B is a power touch panel produced by B & R Automation within the 6PPT Power Touch Panels series. Serving as a compact human-machine interface, it mounts on machine fronts or control cabinets to visualize process variables and forward operator commands to the automation controller. A thin-film-transistor display and an analog resistive touchscreen let operators navigate parameter pages, acknowledge alarms, and enter setpoints even while wearing industrial gloves. Its front-mounted format supports direct interaction at the machine without requiring a separate operator station. It is suited to applications that need a local display and direct touch input in a small footprint.

An ARM Cortex-A8 processor clocked at 600 MHz executes the runtime environment and graphical engine. The unit provides 256 MB of SDRAM for dynamic data, while a nonvolatile 512 MB flash module retains application files, recipes, and trend archives. Visual output appears on a 5.7" active-matrix screen that renders 480 × 640 pixels, aligning with portrait-oriented schematics and status lists common on machinery doors. Color depth reaches 262,144 hues, helping distinguish process states on screen. The analog resistive overlay registers precise touches even with light surface contamination, allowing predictable input during routine industrial use.

Optical clarity is reinforced by a brightness of 400 cd/m² and a contrast ratio of 850:1, so graphics remain legible under factory lighting. Electrical integration requires a nominal supply of 24 VDC; at this level the panel draws up to 319 mA, yielding a peak consumption of 7.66 W. The aluminum enclosure measures 140 mm in width, 172 mm in height, and 47.8 mm in depth, conserving door space on crowded operator stations while still leaving internal volume for passive heat dissipation. The housing size also helps the unit fit installations where usable cabinet or door area is limited.
