Product Description:

The 4B1270.00-K18 unit is an operator interface panel produced by B&R Automation and belongs to the 4B1 PanelWare Panels series. Designed for machine-level HMI tasks, the panel combines a character LCD with tactile keys so operators can issue commands, review status messages, and adjust parameters directly at the equipment. By connecting to the controller network over its integrated CAN bus, the device supports local diagnostics and helps reduce wiring in distributed automation layouts. This format is well suited to machines that need a durable, fixed interface for routine control and message display.

Its power section draws 24 VDC, allowing direct connection to standard control-cabinet supplies without additional conversion hardware. Communications are handled through the CAN interface, and the panel uses a 9-pin D-Sub connector for straightforward integration with compatible fieldbus wiring. Operators read process data on an LCD that presents 4 × 20 characters, a fixed format that suits concise alarms, menus, and setpoint prompts. Under that display sits a membrane keypad whose flat, sealed surface helps keep dust and coolant away from the switch matrix during regular use. CAN isolation is also provided, which helps prevent ground-loop interference between the panel and the network.

The front face measures 120 mm high and 153 mm wide, so the unit fits easily into panel doors with limited available space. The keypad provides 20 total keys, giving users direct access to common functions while allowing clear separation of navigation and command inputs. Visual feedback is improved by 14 LED keys, which let active functions and machine states be identified more quickly during operation. This combination of compact dimensions, dedicated keys, and LED indication makes the panel practical for equipment that relies on simple text-based interaction instead of a larger graphical display.
