OKUMA E4809-045-112数字量控制板卡

产品详细资料
底盘顶部的ELCO连接器将为AI和AO模块之间的4-20 mA信号提供连接；然而，它们不会为HART通信提供路径。始终将现场连接到HART接口模块的前部，以便进行HART通信。警告：对于ATEX应用，外螺纹ELCO连接器必须安装垫圈，并且必须在其五年使用寿命结束前进行更换。（Invensys零件号3000793-001是一个包含25个垫圈的套件。）如图89所示，通过RS-485连接到个扩展机箱中的个HART接口模块、所有后续机箱之间的连接以及终机箱上的端接电阻器，与HART主机PC进行通信。同一机箱中的HART接口模块之间不需要互连，因为RS-485连接是通过8121型增强型低密度扩展机箱背板进行的。HART接口模块上的RS-485连接器有六个触点；A、 B和RS-485接地用于输入和输出。将RS-485接地连接到底盘接地，除非底盘接地和HART控制器的RS-485接地之间存在电位差。
The ELCO connectors at the top of the chassis will provide a connection for the 4-20 mA signals to and from the AI and AO modules; however, they will not provide a path for HART communication. Always make field connections to the front of the HART Interface Modules for HART communication. WARNING For ATEX applications, male ELCO connectors must have a gasket installed, and it must be replaced before the end of its five-year life span. (Invensys part number 3000793-001 is a kit containing 25 gaskets.) As shown in Figure 89, communication with the HART host PC is made using an RS-485 connection to the first HART Interface Module in the first expansion chassis, a connection between all subsequent chassis, and a terminating resistor on the final chassis. No interconnection between HART Interface Modules in the same chassis is needed because the RS-485 connection is made over the Model 8121 Enhanced Low-Density Expansion Chassis backplane. The RS-485 connector on HART Interface Modules has six contacts; A, B and RS-485 ground for input and output. Connect the RS-485 ground to chassis ground unless there is a potential difference between the chassis ground and the RS-485 ground of the HART controller.
