National Instruments SCXI-1334接线端子

NI SCXI-1334（部件号：777687-34）是一款前置安装端子，用于SCXI-1129高密度矩阵。SCXI 1334 将 SCXI-1129 配置为 4 x 64 2 线矩阵，并将信号线直接连接到接线端子内部的螺丝端子。接线端子利用矩阵扩展插头和矩阵扩展电缆，实现瞬时扩行和扩列。无需外部接线。

SCXI-1334具有用于扫描器高级输出和外部输入触发信号的端子。还有两个 128 针 DIN 连接器，用于连接模块之间的列，以及用于通过扩展电缆连接模块之间的行的 10 针接头。用户应记住，该型号的额定测量类别为 I，这意味着它可以承载最大 150 V 的信号电压。NI SCXI 1334 可承受 800 V 最大 的 冲击 电压。此接线端子不能用于连接信号或用于 II、III 或 IV 类内的测量。用户不应连接到 115 或 230 VAC 的电源电路，例如墙上插座。如果危险电压tages （>42.4 Vpk/60 VDC） 存在于继电器端子上，则安全低音量tage （≤42.4 Vpk/60 VDC） 不得连接到另一个继电器端子。

矩阵的列数可以通过使用两个或多个SCXI-1334接线端子来扩展。但是，用户在使用矩阵扩展电缆时只能将相同类型的接线端子连接在一起。连接各种类型的接线端子可能会损坏模块或连接到模块的设备。

【英文介绍】

National Instruments SCXI-1334 wiring terminals

The NI SCXI-1334 (Part number: 777687-34) is a front-mounted terminal for the SCXI-1129 high-density matrix. The SCXI 1334 configures the SCXI-1129 as a 4 x 64 2-wire matrix and connects the signal wires directly to the screw terminals inside the wiring terminals. The terminal uses matrix extension plug and matrix extension cable to realize instantaneous line expansion and line expansion. No external wiring required.

The SCXI-1334 has terminals for the scanner's advanced output and external input trigger signals. There are also two 128-pin DIN connectors for connecting columns between modules, and 10-pin connectors for connecting rows between modules via expansion cables. Users should keep in mind that this model is rated for measurement class I, which means that it can carry a signal voltage of up to 150 V. The NI SCXI 1334 can withstand a maximum impulse voltage of 800 V. This terminal cannot be used to connect signals or for measurements within Class II, III or IV. Users should not connect to a 115 or 230 VAC power supply circuit, such as a wall outlet. If the hazardous voltage tages (>42.4 Vpk/60 VDC) is present on the relay terminal, the safe low Volume tage (≤42.4 Vpk/60 VDC) must not be connected to another relay terminal.

The number of columns in the matrix can be expanded by using two or more SCXI-1334 terminals. However, users can only connect the same type of terminals together when using matrix extension cables. Connecting various types of terminal blocks may damage the module or the device connected to the module.
