The Allen-Bradley 2711P-B15C4D9 is a PanelView 6 plus Human-Machine Interface that helps the user to interface with their machine. The operator can control the user interface through the use of a keypad and touchscreen designed for input of data and information. This module is powered using a power of 18 – 32 volts DC. Also, it has an internal memory of 512 megabytes RAM. Other specifications of the 2711P-B15C4D9 include an optional internal backlight replacement part number 2711P-RL15C. It has approximated shipping dimensions of 20 x 14 x 8 inches and a weight of about 13 lbs.
The Allen-Bradley 2711P-B15C4D9 HMI features EtherNet/IP or Ethernet Industrial Protocol - an open industrial network which supports message exchange, and real-time I/O messaging. It also has an Ethernet port that connects to the controller on the EtherNet/IP network through the use of the network and standard Ethernet connections. This port supports application transfers and printing. EtherNet/IP screen displays and enables the operator to modify some of the EtherNet/IP communication settings for a PanelView terminal. The Allen-Bradley 2711P-RN20 Ethernet communication module is present for 700 - 1500 terminals in case another Ethernet port is needed. The module features a unique IP address.

The 2711P-B15C4D9 comes outfitted with two USB host ports. These ports allow for the connections of supported USB devices such as a keyboard or mouse, a human interface device (HID) with a native device driver, USB flash drives that can be used for extra storage, supported printers, and other devices such as cameras, modems, and bar code readers. The USB ports are identified by the USB icon located at each port. Each host port supports a 0.5 A at 5 VDC. Connected USB devices should not surpass that power capacity. It is recommended that operator’s use a high-speed USB 2.0 certified cable to ensure error-free transmissions. The 2711P-B15C4D9 has a battery-backed internal clock that can timestamp critical data with an accuracy of plus or minus two minutes per month. The battery has a minimum lifespan of 4-year at a temperature of 25 degrees Celsius (77 degrees Fahrenheit). The 15-inch screen is backlit with a cold cathode fluorescent lamp (CCFL) that has a 50,000-hour minimum life at 25 degrees Celsius (77 degrees Fahrenheit). The CCFL backlight is field replaceable. The terminal has a max power consumption of 70 W (2.9 A at 24 VDC), with 39 W (1.6 A at 24 VDC) being the typical consumption. As this is a 1500 terminal, it is recommended that a dedicated 24 VDC safety extra-low voltage (SELV) or protective extra-low voltage (PELV) power supply is used to power the terminal. These types of power supplies protect so that under normal and single fault conditions, the voltage between conductors and earth ground does not exceed a safe value.
