A-B 2711-K6C15 控制网通信端口
2711-K6C15描述:艾伦-布拉德利2711-K6C15终端是一种标准类型的操作员界面终端,在艾伦-布拉德利Panelview 600系列中制造。它的主要功能包括一个带有彩色图形的6英寸屏幕、一个包含可编程功能键的键盘和一个控制网通信端口。2711-K6C15终端在18至32伏DC电压下工作。该终端使用的软件是Panelbuilder 32软件。2711-K6C15终端的键盘除了可编程功能键外,还包括数字键盘和导航键。隔离式安全栅采用了将输入、输出以及电源三方之间相互电气隔离的电路结构,不但有限能功能,还有隔离功能,同时符合本安型限制能量的要求。
A-B 2711-K6C15 控制网通信端口与齐纳式安全相比,虽然价格较贵,但它性能上的突出优点却为用户应用带来了更大的受益其基本功能框图如下: 对比齐纳式和隔离式安全栅的特点和性能后可以看出,隔离式安全栅有着突出的优点和更为广泛用途,虽然其价格略高于齐纳式安全栅,但从设计、施工安装、调试及维护成本来考虑,其综合成本可能反而低于齐纳式安全栅。在要求较高的工程现场几乎无一例外地采用了隔离式安全栅作为主要本安防爆仪表,隔离式安全栅已逐渐取代了齐纳式安全栅。
2711-K6C15 Description: The Allen Bradley 2711-K6C15 terminal is a standard type of operator interface terminal manufactured in the Allen Bradley Panelview 600 series. Its main functions include a 6-inch screen with colored graphics, a keyboard containing programmable function keys, and a control network communication port. The 2711-K6C15 terminal operates at a voltage of 18 to 32 volts DC. The software used for this terminal is Panelbuilder 32 software. The keyboard of the 2711-K6C15 terminal not only includes programmable function keys, but also includes a numeric keyboard and navigation keys. The ***lated safety barrier adopts a circuit structure that electrically ***lates the input, output, and power supply from each other. It not only has limited energy function, but also ***lation function, while meeting the requirements of intrinsic safety limited energy.
The communication port of A-B 2711-K6C15 control network is more expensive compared to Zener type security, but its outstanding performance advantages bring greater benefits to user applications. The basic functional block diagram is as follows: Comparing the characteristics and performance of Zener type and ***lation type security barriers, it can be seen that ***lation type security barriers have outstanding advantages and wider applications. Although their price is slightly higher than Zener type security barriers, from the design, construction and installation Considering the debugging and maintenance costs, the overall cost may actually be lower than that of the Zener safety barrier. Almost without exception, ***lated safety barriers have been used as the main intrinsic safety explosion-proof instruments in highly demanding engineering sites, and ***lated safety barriers have gradually replaced Zener safety barriers.
