Product details

The 1786-RPFM is an Allen-Bradley ControlNet accessory. This module is a Panel Mount / DIN rail mountable device that functions as ControlNet Modular Repeater Medium Distance Fiber Module.

This module is used to for conversion of Cox cable to fiber optic medium with a maximum distance of 3000 meters or 9843 feet. The fiber link provides isolation between connected nodes and provides an increased immunity to noise and electrical disturbances. The fiber link of this module requires use of 62.5/125 micron cable, OM1 multi-mode Fiber optic cable.

The 1786-RPFM is used with the 1786-RPA ControlNet Repeater Adapter module. Up to Four (4) 1786-RPFM may be used with One 1786-RPA. Additionally, mixing repeater types is allowed when assembling a ControlNet network. The maximum allowable total power consumption without damaging the module repeater adapter and nearby modules is 1.6 A @ 5V DC.

The 1786-RPFM is ideally used to extend the total length of One (1) ControlNet segment when used with Point-to-Point or Trunk line topology. It may also be used when planning to build Star and Ring topologies, to establish network with multiple direction from a single point. Additionally, these fiber converter and repeater module may be used if the application crosses an industrial location with known high levels of electrical noises and hazardous areas. The maximum attenuation for a fiber cable must not be higher than 13.3 dB. Typically, cable attenuation for a wavelength of 1300 nm is less than 1.5 dB/km.

RSnetWorx may be used to configure ControlNet properties as well as to qualify if the system being assembled conforms to the ControlNet requirement.
