200针公头或4X50针至200针,60 VDC LFH开关线缆—LFH200电缆用于连接NI PXI-2569、PXI-2570、PXI-2571、PXI-2575、SCXI-1169和SCXI-1175开关模块。该电缆提供三种不同的选项。三种选项的前端均采用200针LFH公头连接,但后端连接各不相同。第一种电缆的后端采用200针裸线公头连接。该选项专门用于PXI-2569/70/71和SCXI-1169。您可以使用无终端末端来满足定制化布线需求,还可扭绞PXI-2569和SCXI-1169的通道和公共接线端导线,以减少串扰。第二种电缆的后端采用4个50针D-SUB母头连接。该选项专门用于PXI-2569/70/71和SCXI-1169。第二种电缆采用与第一种电缆相同的双绞线配置(通道-公共接线端导线扭绞),但提供的是50针D-Sub连接。第三种电缆的后端同样采用4个50针D-SUB母头连接,但如果是在2线配置中,扭绞的是ch+和ch-接线端的导线(CH-CH双绞线)。此选项专门用于PXI-2575和SCXI-1175。
