SCXI-1349    |印刷電路板  | 用于將SCXI系統(tǒng)連接到數(shù)據(jù)采集設(shè)備

　　SCXI-1349(部件號(hào)：182671-01)用于將SCXI系統(tǒng)連接到數(shù)據(jù)采集設(shè)備。 SCXI-1349電纜適配器將68針E系列DAQ設(shè)備(不包括61XXE型號(hào))連接到SCXI模塊(SCXI交換機(jī)模塊除外)。此型號(hào)有三個(gè)連接器。首先，在前面板上，有一個(gè) 68 針公連接器。接下來，在印刷電路板上，有一個(gè) 50 針公分支連接器。最后，在適配器的背面，有一個(gè) 50 針支架安裝的母連接器。

　　National Instruments SCXI-1349 需要使用多個(gè)項(xiàng)目：計(jì)算機(jī)、68 引腳 E 系列 DAQ 設(shè)備、 SCXI-1000、SCXI-1001 或 SCXI-1000DC 機(jī)箱、至少一個(gè) SCXI 模塊(非 SCXI 開關(guān) 模塊)、一把小螺絲刀、安裝指南和 NI SCXI-1349 屏蔽電纜組件，該組件由電纜適配器和一根 68 針屏蔽電纜組成。SCXI-1349 可與 1 m 或 2 m SH68-68-EP 屏蔽電纜一起使用，以將 E 系列設(shè)備連接到 SCXI 機(jī)箱。其他選項(xiàng)是使用0.5 m或1 m SHC68-68-EP電纜或1 m PSHR68-68電纜將DAQCard連接到SCXI機(jī)箱。SCXI-1349 的最大工作電壓為 30 Vrms、42 Vpk 或 60 VDC(信號(hào) + 共模)。

　　用戶必須確保每個(gè)信號(hào)連接都絕緣到NI SCXI 1349可能遇到的最大電壓。接地和其他連接的電源信號(hào)如果超過NI SCXI-1349電纜適配器上的最大信號(hào)額定值，可能會(huì)導(dǎo)致電擊或火災(zāi)危險(xiǎn)。這也可能導(dǎo)致對(duì)連接到 SCXI 機(jī)箱、計(jì)算機(jī)或 SCX 設(shè)備的主板造成損害。

　　NI 設(shè)備 的 推薦 工作 溫度 范圍 為 0 至 50 °C， 存儲(chǔ) 溫度 范圍 為 –20 至 70 °C， 非冷凝 相對(duì)濕度 范圍為 10 至 90%。它的設(shè)計(jì)符合 IEC 61010-1、UL 3111-1 和 CAN/CSA C22.2 No. 1010.1 的電氣測量和測試設(shè)備標(biāo)準(zhǔn)。

　　The SCXI-1349 (Part number: 182671-01) is used to connect the SCXI system to a data acquisition device. The SCXI-1349 cable adapter connects 68-pin E Series DAQ devices (excluding the 61XXE model) to the SCXI module (except the SCXI switch module). This model has three connectors. First, on the front panel, there is a 68-pin male connector. Next, on the printed circuit board, there is a 50 pin cm branch connector. Finally, on the back of the adapter, there is a 50-pin bracket mounted female connector.

　　National Instruments SCXI-1349 requires the use of several items: Computer, 68-pin E Series DAQ device, SCXI-1000, SCXI-1001 or SCXI-1000DC chassis, at least one SCXI module (non-SCXI switch module), a small screwdriver, installation guide, and NI SCXI-1349 shielded cable assembly, The assembly consists of a cable adapter and a 68-pin shielded cable. The SCXI-1349 can be used with 1 m or 2 m SH68-68-EP shielded cables to connect E-Series devices to the SCXI chassis. Other options are to connect the DAQCard to the SCXI chassis using either a 0.5 m or 1 m SHC68-68-EP cable or a 1 m PSHR68-68 cable. The SCXI-1349 operates at a maximum voltage of 30 Vrms, 42 Vpk, or 60 VDC (signal + common mode).

　　The user must ensure that each signal connection is insulated to the maximum voltage that the NI SCXI 1349 May encounter. Grounding and other connected power signals that exceed the maximum signal rating on the NI SCXI-1349 cable adapter may result in an electric shock or fire hazard. This can also cause damage to motherboards connected to SCXI enclosures, computers, or SCX devices.

　　The recommended operating temperature range for NI devices is 0 to 50 °C, the storage temperature range is -20 to 70 °C, and the non-condensing relative humidity range is 10 to 90%. It is designed to comply with IEC 61010-1, UL 3111-1 and CAN/CSA C22.2 No. 1010.1 standards for electrical measurement and test equipment.
