Allen-Bradley B4C20D8 PanelView Plus Compact 400 Key Touch HMI

Allen-Bradley 2711PC-B4C20D8 PanelView Plus 6 Compact 400 Terminal is a compact HMI that pairs a 3.5-inch color display with a keypad and touch input for direct operator interaction in small to mid-size automation applications. This 400-color, 3.5-inch terminal is designed for visualization, alarming, and simple data entry, and is commonly used with CompactLogix controllers to monitor and control processes at the machine level. It provides Ethernet and RS-232 communications for integration with PLCs and industrial equipment, and uses a DC power input for straightforward installation in control cabinets. The B4C20D8 designation identifies a 400-color, keypad/touch input terminal with Ethernet/RS-232 connectivity in the PanelView Plus 6 Compact family, offering a robust operator interface in harsh manufacturing environments. For software, these terminals are configured with FactoryTalk View Machine Edition (ME) software, version 6.10 or later, enabling project deployment and offline design aligned with Rockwell’s contemporary HMI workflow. Typical applications include process monitoring, recipe parameter entry, and status display for machines or lines where a compact, field-deployable HMI is preferred.
