Product Brief
4B1270.00‑490 is B&R Panelware series compact character‑type operator panel, communicating with B&R System2005 controller via galvanic isolated CAN bus.
It adopts 4‑row 20‑character LCD with LED backlight, shows process values, set‑points and alarm texts. 12 LED‑backlit function keys support user‑defined slide‑in labels for convenient on‑site operation. This panel has no local image memory, all display actions are driven by PLC escape‑sequence commands.
Isolated CAN interface restrains ground‑loop interference on industrial cabinet sites, maximum communication distance reaches 1000 m at low baud rate. Front‑panel IP54 rating provides basic dust and splash resistance for cabinet‑mount installation.
This is EOL discontinued spare part, widely used for legacy packaging and textile equipment maintenance. Please confirm CAN‑bus topology and controller compatibility before purchase. Strict ESD protection shall be followed during installation.
