Product Description:

The 4PPC70.057L-20B is a compact Power Panel manufactured by B&R Automation within the 4PPC Power Panels series. This unit combines an x86-based controller and an integrated TFT touch display in one housing, allowing machine builders to mount a single device instead of separate PLC and HMI components. It executes control logic locally and forwards data to higher-level networks, so conveyors, packaging lines, and pick-and-place stations can be synchronized without an external PC. Its fanless design eliminates moving parts, which reduces maintenance in cabinet environments.

At the core of the panel is an Atom E620T processor that operates at 333 MHz, supported by 512 kB of L2 cache to speed up repetitive code segments. The onboard 256 MB of DDR2 DRAM stores dynamic variables, while application code and user screens reside in 2 GB eMMC Flash, which is resistant to vibration. For nonvolatile process counters, the controller reserves 32 kB of FRAM so retained variables survive power loss. Even when every integrated interface is active, power draw remains within 14.4 W, enabling installation on 24 VDC supplies already present in most control panels. This hardware arrangement supports the real-time operating system used by the Power Panel.

Operator interaction is handled by a 5.7 in TFT panel that renders 262,144 colors at a native 480 x 640 px resolution. The screen reaches 400 cd/m² of luminance and has a contrast ratio of 850:1, so status icons remain legible under factory lighting. An analog resistive touch layer allows gloved operators to acknowledge alarms or jog axes without the issues often associated with capacitive surfaces. The unit processes display updates and control tasks within a deterministic window of 0.4 ms, keeping trends and soft keys synchronized with field events.
