Product Description:

The 4D1042.00-590 is an operator interface panel produced by B&R Automation for the 4D PanelWare Panels series. Installed on machine doors or control stations, it serves as a basic human-machine interface that conveys status messages, setpoints, and diagnostic information to personnel working on automated lines. The panel is supplied from the 24 VDC power rail used throughout many control cabinets, allowing it to share the same low-voltage distribution as PLCs, sensors, and relays without additional conversion hardware.

The text display is a monochrome LCD arranged in a 4 x 20 format, meaning four lines with twenty characters each, so operators can scroll through concise menus instead of navigating graphics. Individual characters stand 8.0 mm tall, a size selected to maintain readability from typical arm's-length viewing distances on a factory floor. Characters appear as black on yellow, a high-contrast combination that remains legible under common fluorescent or LED lighting found in production areas. To power the backlight and control logic, the unit draws 180 mA at 24 VDC, which simplifies sizing of the cabinet power supply and leaves margin for additional field devices.

Mechanical tolerance to plant-floor motion is built into the panel. The enclosure withstands a shock load of 15 g applied along any of its three axes, with each pulse lasting 11 msec, so momentary impacts from tooling changeovers do not corrupt data on the display. During normal operation, the assembly endures vibration acceleration up to 9.8 m/sec2 with a peak amplitude of 0.075 mm, executed over twenty sweep cycles per axis. These ratings help keep the display contrast, character alignment, and keypad response stable while the unit is mounted on equipment frames that experience continuous low-level vibration.
