>>>>>型号:2711-K5A2 操作终端 具有集成键盘输入接口
【功能描述】
2711-K5A2 是一款 Allen-Bradley PanelView Standard 操作终端，具有集成键盘输入接口、显示区域、通信端口和内部存储器。该电子设备具有紧凑的组件，支持齐平安装到工业级外壳上。
2711-K5A2 的键盘输入接口由十 （10） 个功能键组成，接受本地和全局分配，使任何按钮都可用于特定功能或接受变量分配。除了功能键外，键盘组件还设置了一个数字键，用于输入数字变量和常量;导航键，用于突出显示屏幕中显示的相应对象。
该操作终端还具有 5.5 英寸单色屏幕，显示区域为 120 x 60 毫米（4.75 x 2.38 英寸），分辨率为 256 x 128 像素。它配备了一个可更换的内部背光，设计用于运行长达 100,000 小时。
这缩短并最大限度地延长了工程时间，因为内部测试也可以在不需要物理硬件的情况下完成。
2711-K5A2 具有一个 170KB 的内部随机存取存储器 （RAM） 和一个 240KB 的非易失性存储器，用于保存应用程序和系统文件，例如趋势、日志和用户手册。
2711-K5A2 安装在 NEMA 或 IP 级外壳上，可提供足够的防水、灰尘、污垢、腐蚀性和爆炸性物质保护。将 2711-K5A2 安装在 NEMA 12/13 型、4X（仅限室内使用）、IP54 和 IP65 或任何等效额定外壳中。
2711-K5A2 是一款 Allen-Bradley PanelView 550 终端。这个过时的操作终端允许用户与其他机器连接。此 PanelView 设备具有 5.5 英寸。单色LCD蓝色模式屏幕。它有一个嵌入式 DH-485 通信端口。用户可以使用位于设备前面板的嵌入式键盘来控制设备。
其 DH-485 通信端口可以连接到 SLC 和 MicroLogix 控制器、DH-485 网络或壁挂式电源。2711-K5A2 端子使用 120 伏交流电源供电。该单元具有 170 KB 的应用程序运行时存储器和 240 KB 的非易失性存储器。本机的内部背光更换部件号为 2711-NL1。终端的大约运输重量和尺寸分别为 6 磅和 14 x 11 x 8 英寸。
