>>>>>型號:2711-K5A2-H 操作終端 具有集成鍵盤輸入接口
【功能描述】
2711-K5A2 是一款 Allen-Bradley PanelView Standard 操作終端，具有集成鍵盤輸入接口、顯示區(qū)域、通信端口和內(nèi)部存儲器。該電子設(shè)備具有緊湊的組件，支持齊平安裝到工業(yè)級外殼上。
2711-K5A2 的鍵盤輸入接口由十 （10） 個功能鍵組成，接受本地和全局分配，使任何按鈕都可用于特定功能或接受變量分配。除了功能鍵外，鍵盤組件還設(shè)置了一個數(shù)字鍵，用于輸入數(shù)字變量和常量;導(dǎo)航鍵，用于突出顯示屏幕中顯示的相應(yīng)對象。
該操作終端還具有 5.5 英寸單色屏幕，顯示區(qū)域為 120 x 60 毫米（4.75 x 2.38 英寸），分辨率為 256 x 128 像素。它配備了一個可更換的內(nèi)部背光，設(shè)計用于運行長達 100,000 小時。
這縮短并最大限度地延長了工程時間，因為內(nèi)部測試也可以在不需要物理硬件的情況下完成。
2711-K5A2 具有一個 170KB 的內(nèi)部隨機存取存儲器 （RAM） 和一個 240KB 的非易失性存儲器，用于保存應(yīng)用程序和系統(tǒng)文件，例如趨勢、日志和用戶手冊。
2711-K5A2 安裝在 NEMA 或 IP 級外殼上，可提供足夠的防水、灰塵、污垢、腐蝕性和爆炸性物質(zhì)保護。將 2711-K5A2 安裝在 NEMA 12/13 型、4X（僅限室內(nèi)使用）、IP54 和 IP65 或任何等效額定外殼中。

【英文介紹】
The 2711-K5A2 is an Allen-Bradley PanelView Standard operating terminal with an integrated keyboard input interface, display area, communication port, and internal memory. The electronics feature compact components that support flush mounting onto an industrial-grade housing.
The 2711-K5A2 keyboard input interface consists of ten (10) function keys that accept local and global assignments, making any button available for a specific function or accepting variable assignments. In addition to function keys, the keyboard component also has a numeric key for entering numeric variables and constants; Navigation key, used to highlight the corresponding object displayed on the screen.
The operating terminal also features a 5.5-inch monochrome screen with a display area of 120 x 60 mm (4.75 x 2.38 inches) and a resolution of 256 x 128 pixels. It comes with a replaceable internal backlight and is designed to operate for up to 100,000 hours.
This shortens and maximizes engineering time, as internal testing can also be done without the need for physical hardware.
The 2711-K5A2 has a 170KB internal random access memory (RAM) and a 240KB non-volatile memory for holding application and system files such as trends, logs, and user manuals.
The 2711-K5A2 is mounted on a NEMA or IP grade housing and provides adequate protection against water, dust, dirt, corrosive and explosive substances. Install the 2711-K5A2 in NEMA Type 12/13, 4X (indoor use only), IP54 and IP65 or any equivalent rated housing.
