Product Description:

The 4B1270.00-K15 operator interface module is built by B & R Automation as part of the 4B1 PanelWare Panels series. It functions as a compact human-machine link for automated equipment, allowing operators to read status messages and enter commands directly at the work zone. By merging a display and keypad in a single portable housing, the unit eliminates the need to walk back to a fixed console during setup, troubleshooting, or product changeovers. This arrangement keeps basic control access close to the process so routine inputs can be made without interrupting nearby machine observation.

The panel runs from a regulated input of 24 VDC ±25%, so it ties into common 24-volt control circuits found in cabinets and pendant cables. Its display shows up to 4 x 20 characters, and the housing is rated IP65, protecting the electronics from dust and low-pressure water jets on the production floor. Operators can toggle between messages rendered in English and Japanese, which supports use in multilingual facilities. The screen is an alphanumeric LC display, providing clear text in reflective lighting conditions while drawing minimal current. Because the unit is not electrically isolated, the supply must share a common reference with the upstream controller.

Readability is improved by characters that are 4 mm high, a size that can be seen easily at arm’s length when the panel is handheld. That character height helps users read prompts, counters, and short alarm text without bringing the unit closer to eye level. Data exchange with the control network occurs over a single CAN link, reducing cable bulk. Field wiring terminates on a screw-clamp connector, enabling quick re-termination without crimp tools. The keypad follows a 12-digit and 12-function layout, and each function key includes an integrated LED so operators receive visual confirmation of active selections.
