1.产 品 详 情 资 料:
TRIO块,如图79所示,是独立的、可配置的I/O块,用于将现场设备连接到CI862通信总线。这些块可以单独安装在机器上、接线盒中,也可以分组安装在机架或面板中。TRIO块由铸铝制成,重量约为1.8千克(4磅)。它的尺寸约为22.5 x 10 x 7.5厘米(9 x 4 x 3英寸)。每个块都有自己的通信能力和微处理器,并提供6到32个电路用于连接输入和输出设备。您可以在总线上以任何组合或顺序放置块。你可以在同一辆公交车上混合使用积木。各种类型的模块可用功能框图完整的CI862K01单元由一个TP862基板、一个CI862通信接口板及其机械组成,如图80所示。所有电子设备和所有功能都位于板上,该板还包括µGenie从模块。基板和CI862通过一个80引脚的边缘连接器连接。与外界的连接是在基板上进行的。
TRIO blocks, Figure 79, are self-contained, configurable I/O blocks used to interface field devices to the CI862 communications bus. These blocks can be individually installed on machines, in junction boxes, or grouped in racks or panels. A TRIO block is made of cast aluminum, and weighs approximately 1.8 kgs (4 pounds). It measures approximately 22.5 x 10 x 7.5 cm (9 x 4 x 3 inches). Each block has its own communications capability and microprocessor, and provides from 6 to 32 circuits for connecting input and output devices. You can place blocks on the bus in any combination or sequence. You can use a mix of blocks on the same bus. Various types of blocks are available Functional Block Diagram A complete CI862K01 unit consists of a TP862 baseplate, a CI862 communication interface board, and their mechanics, Figure 80. All electronic devices and all functions are located on the board which also includes the µGenie slave module. The baseplate and CI862 are connected via an 80-pin edge connector. Connections to the outside world are made on the baseplate.
