PRODUCT INFORMATION
Product Overview
The Allen-Bradley 2711P-K4M20A is a PanelView Operator Terminal designed for industrial process visualization. This operator interface enables real-time monitoring and control across factory automation environments. It pairs directly with programmable logic controllers and automation controllers. The terminal features a 3.5-inch grayscale display with a resolution of 320 by 240 pixels. The display area measures 77 by 58 millimeters for operational viewing. Operators enter data using an integrated keypad with numeric, navigation, and confirmation buttons. Eight programmable function keys allow direct assignment of local and global machine commands.
The unit operates on an alternating current input voltage range of 85 to 264 volts. Integrated communication interfaces include an Ethernet port and a configurable RS-232 serial connection. Network communication over Ethernet utilizes TCP/IP at transmission speeds of 10/100 Mbps. The RS-232 port supports short-distance connections using DF1 or DH485 communication protocols. Two peripheral USB ports support external keyboards, mice, printers, and flash memory drives. The terminal requires flush mounting in a horizontal orientation within compatible industrial enclosures.
