SCXI-1349    |印刷电路板  | 用于将SCXI系统连接到数据采集设备

　　SCXI-1349(部件号：182671-01)用于将SCXI系统连接到数据采集设备。 SCXI-1349电缆适配器将68针E系列DAQ设备(不包括61XXE型号)连接到SCXI模块(SCXI交换机模块除外)。此型号有三个连接器。首先，在前面板上，有一个 68 针公连接器。接下来，在印刷电路板上，有一个 50 针公分支连接器。最后，在适配器的背面，有一个 50 针支架安装的母连接器。

　　National Instruments SCXI-1349 需要使用多个项目：计算机、68 引脚 E 系列 DAQ 设备、 SCXI-1000、SCXI-1001 或 SCXI-1000DC 机箱、至少一个 SCXI 模块(非 SCXI 开关 模块)、一把小螺丝刀、安装指南和 NI SCXI-1349 屏蔽电缆组件，该组件由电缆适配器和一根 68 针屏蔽电缆组成。SCXI-1349 可与 1 m 或 2 m SH68-68-EP 屏蔽电缆一起使用，以将 E 系列设备连接到 SCXI 机箱。其他选项是使用0.5 m或1 m SHC68-68-EP电缆或1 m PSHR68-68电缆将DAQCard连接到SCXI机箱。SCXI-1349 的最大工作电压为 30 Vrms、42 Vpk 或 60 VDC(信号 + 共模)。

　　用户必须确保每个信号连接都绝缘到NI SCXI 1349可能遇到的最大电压。接地和其他连接的电源信号如果超过NI SCXI-1349电缆适配器上的最大信号额定值，可能会导致电击或火灾危险。这也可能导致对连接到 SCXI 机箱、计算机或 SCX 设备的主板造成损害。

　　NI 设备 的 推荐 工作 温度 范围 为 0 至 50 °C， 存储 温度 范围 为 –20 至 70 °C， 非冷凝 相对湿度 范围为 10 至 90%。它的设计符合 IEC 61010-1、UL 3111-1 和 CAN/CSA C22.2 No. 1010.1 的电气测量和测试设备标准。

　　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.
