The 2711-T6C2L1 is a Human Machine Interface (HMI) device from Allen-Bradley. It is a visualization component with the primary intention of integrating data and logic of Programmable Logic Controllers (PLC) and provide graphical representation that may be custom designed to directly represent the process in a downscaled format or any other representation that provides access to the main monitoring and control points of the machine or process.

The 2711-T6C2L1 is designed to be powered by an external 24VDC supply voltage with an applicable voltage range of 18-32VDC. It has an internal memory of 240K bytes that may be expanded up to 32MB of memory. It has a Active Matrix TFT with Cold Cathode Fluorescent (CCF) Backlight display with display area of 115 x 87 mm (4.54 x 3.43 in.) and resolution of 320 x 240 pixels. The integrated backlight is designed to operate up to 50,000 hours, 1/2 life when operated at 25 °C (77 °F) Operators interact to the process by means of the touch input interface that is made of 128 touch cells with each cells measuring 20 x 30 pixels. It is recommended to operate this operator terminal with a gloved finger or a stylus to protect the touch membrane. Servicing of the touch sensititve surface may also be accomplished using a soft cloth partially wetted with mild soap solution to remove contaminants commonly present in site such as oil, dust and grease.

The 2711-T6C2L1 has a DH485 communication port which supports communication with DH485 enabled devices as well. It supports communication rates of 1200, 2400, 9600, 19.2K with maximum cable distance of 1219 m (4,000 ft). It also has an internal memory of 240Kbytes.

The Allen-Bradley 2711-T6C2L1 touchscreen terminal operates with a DC voltage range of 18 to 32 Volts DC.

It is important to know all the particularities of the proper installation process when installing the Allen-Bradley 2711-T6C2L1 terminal. It should not be mounted in an external environment where ultraviolet rays could damage or reduce the life of its touchscreen. This touchscreen should be operated with a stylus or with a glove, and the users need to be careful not to scratch the screen through the use of sharp objects. This is a 6-inch touchscreen. The Allen-Bradley 2711-T6C2L1 touchscreen terminal is able to withstand a maximum temperature of 50 degrees Celsius. It comes with a communication port and it also includes a series of alarms that indicate different kinds of machine status updates or errors. This terminal has a weight of 2 pounds and dimensions of 6 x 7.28 inches.
