2.產 品 詳 情 資 料：
NI PXIe-4145 隔離/中繼器轉換器用戶在隔離中繼器/轉換器上感興趣的項目如下所述。兩個25針D型陰連接器（兩個25引腳陽連接器，D型連接器（焊料罐））用于用戶電纜。NI PXIe-4145 5/230 VAC電源連接（內部）4位端子塊。三位撥動開關位于裝置背面，根據隔離中繼器/轉換器邏輯圖后面所示的系統配置進行設置。下圖提供了裝置的功能視圖。注意用于控制J端口變送器的3位開關。此開關將在本附錄后面的系統配置中討論。注：所有輸入都偏向非活動狀態。未連接的輸入將在相應的輸出上產生二進制（OFF）狀態。NI PXIe-4145 NC=無連接SD（發送數據）和RD（接收數據）與TXD和RXD（用于六系列PLC）相同。（A） 和（B）與–相同，+A和B表示輸出，A'和B'表示輸入
Isolated/Repeater Converter Items of interest to the user on the Isolated Repeater/Converter are described below.NI PXIe-4145 Two 25-pin female D-type connectors (Two 25-pin male, D-type connectors (solder pot), are included for user cabling.5/230 VAC power connection (internal) 4-position terminal bloc . Three-position toggle switch, recessed in the back of the unit, is set according to the system configurations shown later in this appe Logic Diagram of the Isolated Repeater/Converter The figure below provides a functional look at the unit. Note the 3-position switch for controlling the JNI PXIe-4145 port transmitters. This switch is discussed in System Configurations later in this appendix Note: All inputs are biased to the inactive state. Inputs left unconnected will produce a binary NI PXIe-4145 (OFF) state on the corresponding output.NC=No Connection SD (Send Data) and RD (Receive Data) are the same as TXD and RXD (used in the Series Six PLC). (A) and (B) are the same as – and + A and B denote outputs, and A’ and B’ denote inputs
