The \"RR\" designation signifies a Right-to-Right bank connection, allowing for flexible system architectures where I\/O banks are positioned in non-linear configurations, such as side-by-side mounting within a control cabinet. This cable effectively extends the 1769 backplane, enabling the controller to communicate with I\/O modules located across separate DIN rails or bank segments.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRight-to-Right Configuration:\u003c\/strong\u003e Designed for specific physical orientations where bank connections require right-side alignment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Compatibility:\u003c\/strong\u003e Fully compatible with Allen-Bradley CompactLogix and MicroLogix 1500 I\/O platforms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach:\u003c\/strong\u003e Provides a 1-meter (3.28 ft) cable length for bridging I\/O banks within a single enclosure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal Integrity:\u003c\/strong\u003e Maintains robust backplane communication across expanded distances.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThis expansion cable is used in industrial automation environments requiring distributed I\/O across multiple DIN rails.
