Allen-Bradley 2711P-T7C21D8S

The 2711P-T7C21D8S is a PanelView Plus 7 Standard Terminal that is manufactured by Allen-Bradley. The 2711P-T7C21D8S uses touch for its operator input and utilizes a color TFT LCD screen. The diagonal display size for this terminal is 6.5 inches and it has a viewing area of 132.99 millimeters. The display resolution is 640 x 480 VGA with 18-bit color graphics. It has an aspect ratio of 4:3 and a typical brightness of 300 nits. The 2711P-T7C21D8S terminal has a backlight lifespan of 50,000 hours at a minimum of 40 degrees Celsius to half-brightness (backlight not replaceable). Touch screen specifications include it being analog resistive and having an actuation rating of 1 million presses; operating force is 100 grams. The 2711P-T7C21D8S has system memory up to 512 Megabytes of RAM and 512 Megabytes of storage, while user memory is 80 Megabytes of non-volatile storage for applications. The 2711P-T7C21D8S includes one DC card slot for storing application files; the possible replacements for this part are the Allen-Bradley 1784-SD1 (1 GB), 1784-SD2 (2 GB), 1784-SDHC8 (8 GB), and 1784-SDHC32 (32 GB).

Electrical specifications for the 2711P-T7C21D8S include a DC input voltage of 24 Volts DC nominal (18…30 Volts DC) and a DC power consumption of 50 Watts maximum (2.1 Amperes at 24 Volts DC). The 2711P-T7C21D8S has a DIN rail power supply, AC-to-DC, 85…265 Volts AC, 47…63 Hertz. The recommended replacement power supply is the Allen-Bradley 2711P-RSACDIN. Mechanical specifications include an approximate weight of 0.85 kilograms, or 1.86 pounds. Approximate dimensions are 170 x 212 x 56.5 millimeters, or 6.69 x 8.35 x 2.22 inches.

Part number 2711P-T7C21D8S is an Allen-Bradley PanelView Plus 7 operator terminal. This device's main purpose is to provide a means for communication between a controller, which is typically a ControlLogix, and the operator.  To help with any and all communication needs/purposes, this terminal has been embedded with 1 (one) Ethernet port, as well as 2 (two) USB ports. These USB ports are an USB host port and an USB Device port. In order to create HMI applications, text displays and animated graphics have been introduced. These displays and graphics provide an operator with a view of the state of operation of any machines or factory processes that are connected via this terminal. This Allen-Bradley terminal has a maximum connection number of 1 (one) controller, 100 (one hundred) screens, and 500 (five hundred) alarms. Additionally, Ethernet communication from this terminal supports linear and network star topology. This terminal does not support ring topology as the DLR option is not included with this terminal. While connected to the Ethernet network, this terminal is typically connected to various controllers, such as the ControlLogix5570 or the CompactLogixTM 5370.

During the mounting process of installing this operator terminal, it is important to make note of the minimum clearance each side of the terminal needs to allow for proper ventilation and cables. The top of the terminal requires at least fifty-one millimeters (51 mm) of clearance. The bottom of the device also requires fifty-one millimeters (51 mm) of clearance. On the side of the terminal that does not have the SD card, the required minimum clearance is twenty-five millimeters (25 mm). However, on the side with the SD card, the clearance requirement is fifty-one millimeters (51 mm) again. This terminal may be used in temperatures that range from 32 to 131 degrees Fahrenheit.

The Allen Bradley 2711P-T7C21D8S is a PanelView Plus 7 Operator Terminal. It is a standard terminal option from PanelView Plus 7 series. The terminal has a color TFT LCD touch screen that measures 6.5 inches in size and a single Ethernet/IP port. The resolution of its VGA display is 640x480 pixels. The terminal's screen has a 4:3 aspect ratio. The terminal has an internal memory of 512 MB RAM and 512 MB nonvolatile memory, with 80 MB user-free storage that can be increased using internal memory cards and flash drives. The terminal can establish and perform connections to one controller and up to 100 screens and many alarms. The Ethernet communication port supports linear and star topologies (for the ring topology, the DLR option must be included). Usually, this terminal is connected to ControlLogix5570 or/and CompactLogix 5370 controllers on an EtherNet/IP network. The terminal operating temperature should be 0 to 55 degrees Celsius (32 to 131 degrees Fahrenheit) with a usual humidity range of 5 - 95% of relative humidity.
