Product Overview

The Allen-Bradley 1769-CRR1 provides a high-speed communication link for expanding CompactLogix and MicroLogix 1500 I/O banks. This 0.3-meter (approximately 1 foot) cable connects the right side of one I/O bank to the right side of a subsequent bank. By extending the 1769 communication bus, the 1769-CRR1 allows for complex, multi-rack system architectures without compromising signal integrity. We provide this unit in 100% Brand New original condition, ensuring a secure, low-impedance connection for your industrial control network.

Engineering Advantages

The 1769-CRR1 solves critical layout challenges in high-density control cabinets where a single, continuous rail of I/O modules is physically impossible.

Split-Bank Versatility: This cable allows engineers to split I/O modules into two separate rows or "banks." This proves essential when cabinet depth or width constraints prevent a long, single-rail installation.
Maintained Bus Performance: The 1769-CRR1 preserves the high-speed backplane throughput of the CompactLogix system. It ensures that data from distal I/O banks reaches the controller with the same deterministic timing as local modules.
Right-Bank Optimization: The "Right-to-Right" configuration specifically facilitates vertical stacking. You can connect the end of a top row to the beginning of a bottom row, creating a compact "S" pattern for your I/O layout.
Industrial Shielding: The cable assembly features heavy-duty shielding to protect the communication bus from electromagnetic interference (EMI) typically found near variable frequency drives (VFDs) and high-power contactors.
Locking Connectors: Secure, heavy-duty connectors prevent accidental disconnection due to machine vibration, ensuring continuous uptime for process-critical applications.

FAQs

Does the 1769-CRR1 require a separate power supply for the second bank?

Yes. When you use an expansion cable to create a new bank, you must install an additional 1769-PA2, 1769-PB2, or 1769-PA4 power supply to support the modules on that expanded bank.
How many expansion cables can I use in a single CompactLogix system?

The total number of expansion cables depends on the specific controller's I/O bank limit. Most CompactLogix controllers support up to two expansion cables (three banks total). Always verify your controller's "distance rating" and bank capacity in the technical manual.
What is the difference between a 1769-CRR1 and a 1769-CRL1?

The 1769-CRR1 connects a Right Bank to a Right Bank (typically used for stacking). The 1769-CRL1 connects a Right Bank to a Left Bank. Ensure you select the correct cable based on your physical rack orientation and port locations.
Is the cable flexible enough for tight cabinet turns?

The 0.3m length provides sufficient slack for standard DIN rail spacing (row-to-row). While the cable is ruggedized, you should avoid exceeding the minimum bend radius to ensure long-term bus reliability.
