Description

Allen-Bradley 1786-RPFM is an important product of the ALLEN-BRADLEY brand of Rockwell Automation.The following is a detailed introduction to the product:

1.Product Overview

1786-RPFM belongs to the mid-range optical fiber relay module in the Allen-Bradley ControlNet series.It is mainly used to convert copper coaxial cables into optical fiber media to improve the anti-interference ability and transmission distance of the network.This module has a wide range of applications in the field of industrial automation,especially in systems that require stable communication connections and remote control.

2.Main features

Media Conversion:The 1786-RPFM converts ControlNet’s copper coaxial cable to fiber optic media,providing superior node isolation and being more immune to interference in noisy environments than copper media.

Network expansion:This module can significantly extend the length of the ControlNet network and supports star,ring and point-to-point network topologies,thereby extending the coverage of the entire network.

Communication rate and distance:Supports communication rates up to 5 Mbps,and the maximum transmission distance is up to 3000 meters(9843 feet).
