1786-RPFM 面板安装 DIN导轨安装设备

1786-RPFM是Allen-Bradley ControlNet附件。该模块是一个面板安装/ DIN导轨安装设备，用作ControlNet模块化中继器中距离光纤模块。

该模块用于将Cox电缆转换为光纤介质，最大距离为3000米或9843英尺。光纤链路在连接的节点之间提供隔离，并提高了对噪声和电气干扰的抗扰度。该模块的光纤链路需要使用62.5/125微米光缆，OM1多模光缆。

1786-RPFM 与 1786-RPA ControlNet 中继器适配器模块一起使用。最多四 （4） 个 1786-RPFM 可与一个 1786-RPA 一起使用。此外，在组装 ControlNet 网络时，允许混合中继器类型。在不损坏模块中继器适配器和附近模块的情况下，允许的最大总功耗为 1.6 A @ 5V DC。

当与点对点或干线拓扑一起使用时，1786-RPFM 非常适合用于扩展一 （1） 个 ControlNet 网段的总长度。在规划构建星形和环形拓扑时，也可以使用它，以从单个点建立具有多个方向的网络。此外，如果应用跨越已知具有高电噪声水平和危险区域的工业场所，则可以使用这些光纤转换器和中继器模块。光缆的最大衰减不得高于 13.3 dB。通常，波长为1300 nm的电缆衰减小于1.5 dB/km.RSnetWorx

The 1786-RPFM is an Allen-Bradley ControlNet attachment. The module is a panel mount/DIN rail mount device used as a ControlNet modular repeater mid-range fiber optic module.

The module is used to convert Cox cables into fiber optic media over a maximum distance of 3,000 meters or 9,843 feet. Fiber optic links provide isolation between connected nodes and improve immunity to noise and electrical interference. The optical fiber link of the module requires the use of 62.5/125 micron fiber cable, OM1 multi-mode fiber cable.

The 1786-RPFM is used with the 1786-RPA ControlNet repeater adapter module. Up to four (4) 1786-RPFMs can be used with one 1786-RPA. In addition, mixing repeater types is allowed when assembling the ControlNet network. The maximum allowable total power consumption is 1.6A@5V DC without damaging the module repeater adapter and nearby modules.

When used with point-to-point or trunk topologies, the 1786-RPFM is ideal for extending the total length of one (1) ControlNet network segment. It can also be used when planning to build star and ring topologies to build a network with multiple directions from a single point. In addition, these fiber optic converters and repeater modules can be used if applications span industrial sites known to have high electrical noise levels and hazardous areas. The maximum attenuation of the cable shall not be higher than 13.3 dB. Typically, cables with a wavelength of 1300 nm have attenuation less than 1.5 dB/km.RSnetWorx
