The Allen-Bradley 1797-RPFM is a ControlNet Ex Fiber Repeater Module from Rockwell Automation’s 1797 FLEX Ex series, designed for use in hazardous area environments. This module operates in conjunction with the 1797-RPA to form a repeater hub, enabling the extension of ControlNet Ex network segments for broader system coverage. The 1797-RPFM is a medium-range fiber module equipped with two (2) fiber link channels that support reliable data transmission between ControlNet nodes. Engineered for high-performance communication in intrinsically safe applications, this module ensures stable network integrity and efficient connectivity across extended industrial Ethernet infrastructures.
