Product Description:

The 4PPC70.0702 is a combined human-machine interface and control unit produced by B&R Automation as part of the 4PPC Power Panels series. By integrating an embedded processor, solid-state storage, and a 7-inch touch screen in one enclosure, the unit simplifies cabinet layouts and provides local visualization, recipe handling, and motion coordination for automated equipment. It mounts directly on the machine front and communicates with I/O modules, drives, and supervisory PLCs over industrial networks. This integrated format is useful where local control and operator access need to be housed in a single panel device.

Processing tasks are handled by a 333 MHz Intel Atom E620T that supports deterministic control loops while keeping thermal output low. Application code and the operating system run from 256 MB of DDR2 DRAM, while retentive variables are safeguarded in 32 kB of FRAM. Program and recipe files reside in a soldered 2 GB flash drive, eliminating rotating media. Operator interaction occurs on a 7.0 in analog-resistive touch display that renders 800 × 480 pixels, allowing finger or stylus input even when gloves are worn. This arrangement supports responsive screen updates and direct handling of local machine data.

The aluminum front panel carries an IP65 rating, so washdown splashes and airborne dust do not enter the electronics. Entire system demand peaks at 15 W, permitting installation in fanless cabinets and reducing load on uninterruptible power supplies. Compact mechanics measuring 197 mm in width, 140 mm in height, and 51 mm in depth combine with a mass of 0.65 kg to ease swing-arm or pendant mounting. Backlight life is rated for 50,000 h to first half-luminance, supporting long maintenance intervals in continuous-duty production lines. Writable endurance of 40 TB allows trend data and event logs to be recorded over long operating periods without quickly wearing out the flash memory cells.
