National Instruments SCXI-1314 通用应变接线端子
SCXI-1314(部件号:777687-14)是为与SCXI-1520通用应变/桥模块一起使用而设计的。 这种组合允许用户通过螺丝端子轻松连接应变片。该接线端子上的 88 个螺丝端子配置为 8 组,每组 11 个螺丝端子。每组对应SCXI-1520模块上的一个通道。每个通道输入都有螺丝端子,连接到SCXI-1520的输入端。此外,还有两个精密100 kΩ分流校准电阻和一个精密四分之一桥完成电阻。
SCXI 1520模块具有继电器,可将电阻器切换入和移出输入电路,以提供分流校准和四分之一桥完成。四分之一桥完成电阻器的出厂默认值为 350 Ω,可与 350 Ω 应变片配合使用。电阻器安装在接线端子上的插座中,因此用户可以毫不费力地将其更换为适合用户特定应变片的电阻器。如果用户的应用需要 120 Ω 应变片,则可以使用 8 个 120 Ω电阻器。
安装SCXI-1314接线端子需要几个项目。首先,需要SCXI机箱。用户还需要 SCXI-1520 模块、8 个用于四分之一桥完成电路的精密 120 Ω电阻器(取决于应用)、电线绝缘剥线器、电线剪、长嘴钳、1/8 英寸。一字螺丝刀、1 号和 2 号飞利浦螺丝刀,以及 SCXI-1314 和 SCXI-1520 的安装指南/用户手册。
SCXI-1314使用NIDAQmx驱动程序软件运行,该软件与LabVIEW、LabWindows/CVI或Measurement Studio等软件包/应用开发环境(ADE)兼容。
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%。它的设计符合以下电气设备安全标准:IEC 61010-1、EN 61010-1、UL 61010-1 和 CAN/CSA C22.2 No. 61010-1。

【英文介绍】
National Instruments SCXI-1314 Universal strain terminal
The SCXI-1314 (Part number: 777687-14) is designed for use with the SCXI-1520 Universal strain/bridge module. This combination allows the user to easily connect the strain gauge via screw terminals. The 88 screw terminals on the wiring terminal are configured in 8 groups with 11 screw terminals in each group. Each group corresponds to a channel on the SCXI-1520 module. Each channel input has screw terminals connected to the SCXI-1520 input. In addition, there are two precision 100 kΩ shunt calibration resistors and a precision quarter bridge finish resistor.
The SCXI 1520 module has relays that switch resistors in and out of the input circuit to provide shunt calibration and quarter-bridge completion. The quarter-bridge finish resistor has a factory default of 350 Ω and can be used with 350 Ω strain gauges. The resistor is installed in a socket on the terminal, so the user can effortlessly replace it with a resistor that fits the user's specific strain gauge. If the user's application requires a 120 Ω strain gauge, eight 120 Ω resistors can be used.
Installing SCXI-1314 terminals requires several items. First, you need the SCXI chassis. Users also need SCXI-1520 modules, 8 precision 120Ω resistors for quarter-bridge finish circuits (depending on application), wire insulation strippers, wire cutters, long nose pliers, 1/8 inch. Installation guides/user manuals for flat-head screwdrivers, Philips screwdrivers No. 1 and No. 2, and SCXI-1314 and SCXI-1520.
The SCXI-1314 runs with NIDAQmx driver software, which is compatible with packages/application development environments (ades) such as LabVIEW, LabWindows/CVI or Measurement Studio.
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 the following electrical equipment safety standards: IEC 61010-1, EN 61010-1, UL 61010-1 and CAN/CSA C22.2 No. 61010-1.
