Part number 2711P-T12W22A9P is a PanelView Plus 7 series human machine interface (HMI) operator terminal with applications in local or remote control of plant machinery. This HMI device manufactured by Allen-Bradley / Rockwell Automation has an external voltage requirement of 100 to 240 volts AC and has a power consumption of 105 VA. This device is equipped with a 12.1-inch display with a resolution of 1280 x 800 WXGA, 18-bit graphics, and a 16:10 aspect ratio. The display is characterized by color active-matrix and thin-film transistor (TFT). It also has an LCD wide aspect ratio screen.

This HMI uses an embedded analog touchscreen interface for control and input. The resistive touchscreen is designed for an actuation rating of 1 million presses with 100 g/ press force. It has a backlight for screen lighting with brightness of typically 300 cd/m2. The backlight is non-replaceable and is designed for prolonged operation with a minimum half-life operation of fifty thousand (50,000) hours. The HMI operator also has a battery powered real-time clock (RTC) with a ±2 minutes/month accuracy, and a 4-year life minimum. External communication in the HMI is possible using 2 Ethernet and 3 USB ports. The operator also supports LEDs in the back for fault/run status indication.

The 2711P-T12W22A9P has an expandable system memory of 512 MB RAM, storage of 512 MB, and non-volatile user memory of 80 MB for applications. Additional storage is achieved through external SD cards and flash drives. The 2711P-T12W22A9P operator terminal has an approximate weight of 2.28 kilograms (5.03 pounds) and physical dimensions that measure 9.69 x 13.39 x 2.74 inches, with a display screen measuring 261 x 163 mm (10.3 x 6.4 inches).
