Product Description:

B & R Automation’s 4D PanelWare Panels series includes the 4D1044.00-090 operator panel. This LCD text display module installs on machine fronts and control cabinets, where it relays status messages and menu prompts to maintenance staff and PLC operators. By integrating a dedicated text screen and keypad into the automation network, the panel streamlines user interaction, alarm indication, and parameter entry without consuming a full graphic HMI slot.

The module presents four text rows, each able to hold 40 characters, on a monochrome LCD that renders black-on-yellow characters for high legibility in factory lighting. Character glyphs stand 4.3 mm tall, meeting the ergonomic minimum for arm-length viewing distances. Illumination comes from an internal LED backlight that avoids cathode-ray aging and keeps power draw to 155 mA at 24 VDC, which can be supplied directly from common control-bus power. This electrical budget simplifies wiring because no separate high-voltage source is required. The monochrome layout, combined with the fixed character matrix, lowers processor load in the host PLC, speeding refresh when fault strings update during runtime.

Installation is straightforward: an enclosure width of 288 mm, height of 96 mm, and depth of 35 mm match standard 19-inch panel cutouts, while the aluminum housing is finished with a blue coating that resists oil staining. During transport or seismic mounting conditions, the device withstands shocks up to 15 g along all three axes and endures 20 vibration cycles per axis, preventing display dropout in mobile machinery. The module’s passive mechanical design frees the front door from cooling fans, and its operating clearance remains unchanged by the PanelWare bezel, ensuring stackability with neighboring controllers inside crowded cabinets.
