normal style="MARGIN: 0cm 0cm 0pt 47.45pt; TEXT-INDENT: -47.45pt; LINE-HEIGHT: 12pt; mso-char-indent-count: -4.5">产品简介: TD-1204 是一款光隔离数据通信集线器,通过特殊设计,将总线挂接式连接方式转变为RS-485/RS-422星型连接方式(TD-1204仅支持RS-485),该产品能够把一路RS-485总线分割为4路RS-485总线的集线器。它专为解决复杂电磁场环境下RS-485大系统要求而设计的，并提供灵活的RS-485/RS-422星型总线结构。各端口都具有短路、开路保护，在发生故障的时候，保证每一端口都自带隔离功能,起到互不干扰的效果。出现问题的端口将被隔离,以确保其它网段的正常工作.该集线器为RS-485总线大系统中带来了即方便又可靠的连接方法，是改变原有总线单一式结构的最佳选择！
