Allen-Bradley 1769-CRR1 Right-to-Right Bus Expansion Cable – CompactLogix 1769 Series
When a CompactLogix control system cannot physically accommodate all required I/O modules within a single bank, production lines stall, engineers scramble for workarounds, and costly downtime accumulates. Without a reliable bus expansion solution, system architects are forced into expensive controller upgrades or compromised panel layouts that sacrifice maintainability. The Allen-Bradley 1769-CRR1 eliminates this constraint entirely — it is the purpose-engineered right-to-right bus expansion cable that connects two CompactLogix 1769 I/O banks, preserving full backplane communication integrity across the expanded system.
Within the Rockwell Automation CompactLogix 1769 ecosystem, the 1769-CRR1 occupies a critical infrastructure role. It is the right-bank-to-right-bank variant of the 1769 bus expansion cable family, designed specifically for multi-bank configurations where the controller bank must communicate with one or more remote I/O banks mounted to its right side. As CompactLogix systems have become the de facto standard for mid-range industrial automation globally — deployed across automotive, food & beverage, oil & gas, and discrete manufacturing — the 1769-CRR1 has become an indispensable component in thousands of control panel builds worldwide.

Frequently Asked Questions
- Q: What is the difference between 1769-CRR1 and 1769-CRL1?
- A: The 1769-CRR1 connects the right end of one bank to the right end of an adjacent bank (right-to-right). The 1769-CRL1 connects the right end of one bank to the left end of another (right-to-left). The correct cable depends on your physical panel layout and bank mounting orientation.
- Q: How many expansion banks can I connect using the 1769-CRR1?
- A: The CompactLogix 1769 system supports up to 3 expansion banks beyond the controller bank, subject to the total I/O module count and power budget of your specific controller model. Consult Rockwell Automation publication 1769-UM011 for detailed system sizing guidelines.
- Q: Is the 1769-CRR1 compatible with all CompactLogix controllers?
- A: The 1769-CRR1 is compatible with all controllers that support the 1769 I/O platform, including CompactLogix 5370 (L1, L2, L3) and earlier CompactLogix families. It is not compatible with CompactLogix 5380/5480 (Compact 5000 I/O platform).
- Q: Can Konmask.com provide a certificate of conformance?
- A: Yes. A certificate of conformance and inspection report are available upon request for all orders. Please specify this requirement when submitting your inquiry.
- Q: What is the typical lead time for the 1769-CRR1?
