Product Description:
The 4MP281.0571-12 is a handheld human-machine interface from B&R Automation in the 4MP Mobile Panels series. It is designed for mobile operation of industrial equipment, letting operators start, stop, and supervise machines while positioned directly at the work zone. A built-in display, processor, and communication ports form a self-contained control point, so no fixed cabinet panel is required. Because the panel can be used close to the machine, status and control functions remain available where process conditions are easiest to observe, which supports setup, troubleshooting, and minor adjustments on automated production lines.
The panel runs on a Geode SC2200 CPU clocked at 266 MHz. Working memory consists of 64 MB of SDRAM, 256 kB of battery-backed SRAM for retentive data, and 4 MB of graphics RAM for an LCD with a diagonal size of 5.7 in. The display renders at 320 x 240 px, delivers 120 cd/m² of brightness, and has a contrast ratio of 250:1, while its cold-cathode backlight is rated for 50,000 h. Ethernet communication reaches 100 Mbit/s through the integrated RJ45 interface, enabling rapid transfer of screen objects and program updates from higher-level controllers.
Fourteen tactile soft keys line the bezel, and a resistive touch layer supports finger or stylus input for fine cursor placement. For legacy integration, the COM1 port sustains data exchange up to 115 kbit/s, allowing connection to existing PLCs that rely on asynchronous serial links. The electronics are powered from a single 24 VDC supply, which simplifies field wiring on gantry arms or mobile carts. This combination allows the unit to host compact visualization projects while preserving important recipe or counter values during power interruptions.
