Allen-Bradley 2711P-K12C4A8

The 2711P-K12C4A8 is a PanelView Plus 6 Terminal that is manufactured by Allen-Bradley. It uses an x86 – 1.0 Gigahertz CPU. The 2711P-K12C4A8 comes standard with a color active matrix, thin film transistor (TFT), liquid crystal display (LCD) with an analog resistive touch screen and an actuation rating of 1 million presses. Operating force for the touch screen is 10…110 g and 340 g for keypad operating force. The 2711P-K12C4A8 has a real-time clock that is battery backed and accurate up to +/- 2 minutes per month; It has a battery life of 4 years minimum at 25 degrees Celsius (77 degrees Fahrenheit). The 2711P-K12C4A8 offers memory up to 512 Megabytes of nonvolatile flash and 512 Megabytes of RAM. It has status indicators for COMM (green) and Fault (red). Electrical specifications for the 2711P-K12C4A8 include a DC input voltage of 24 Volts DC (nominal – 18…32 Volts DC) and a power consumption of 70 Watts maximum (2.9 Amperes at 24 Volts DC) and 39 Watts typical (1.6 Amperes at 24 Volts DC). AC input voltage in 85…264 Volts DC and the 2711P-K12C4A8 has a line frequency of 47…63 Hertz. Power consumption (AC) is 160 Volt-amperes maximum and 65 Volt-amperes typical.

Environmental specifications include an operating temperature ranging between 0 and 55 degrees Celsius (32 to 131 degrees Fahrenheit) and a nonprotein temperature between -25 and 70 degrees Celsius (-13 to 158 degrees Fahrenheit). The 2711P-K12C4A8 has a heat dissipation of 240 British Thermal Units (BTU) per hour and a relative humidity between 5% and 95% (non-condensing). Both operating and nonprotein shocks are rated as 15 g at 11 milliseconds; the 2711P-K12C4A8 has an enclosure rating of NEMA Type 12, 13, 4X (indoor use only), and IEC IP54 and IP65. The 2711P-K12C4A8 has agency certifications for c-UL-us, CE (EMC), CE (LVD), C-Tick, and Marine.

The 2711P-K12C4A8 is made up of modular components that allow for the terminal to be easily customizable and upgradable, and allows for a quick installation process. The modular components consist of the display module, the logic module, and potentially the optional communication module. The display module for this terminal consists of the color display screen and the keypad input system. The logic module for the 2711P-K12C4A8 consists of the AC power input, the communication ports, the terminal’s internal memory, the SD card slot, battery-backed clock, two status indicators, and reset switches. The 2711P-K12C4A8 terminal comes outfitted with an RS-232 port. This means that it can print messages that have been triggered in a message display, alarm messages, and alarm lists. Operators can set the print attributes of objects and alarms in each application. Printing is considered to be a background operation. This means that, while printing, the 2711P-K12C4A8 can continue any updates and can also continue performing other terminal functions. When printing, the terminal prints messages in the order that they are received. The terminal will alert operators if the print buffer is full. When this happens, new print requests are automatically aborted. However, the print queue is not maintained between the terminal’s power cycles and any messages are cleared  when the power is reset. Operators can configure various information using the terminal's built-in Ethernet driver. Using the Ethernet driver, operators can alter the name of the device that is shown on the network, edit the username and password that are needed to access the network, and configure the terminal's IP address. Take care not to connect or disconnect the Ethernet cable while power is being applied to the terminal, as it can cause an electrical arc.
