Frequently Asked Questions
Q: What is the maximum distance supported by the 1757-SRC1 cable?
A: The standard 1757-SRC1 is 1 meter long. For extended distances, consider the 1757-SRC3 (3 meters) or custom fiber solutions.
Q: Can I use third-party fiber optic cables instead?
A: Allen-Bradley recommends using genuine 1757-SRC cables to ensure compatibility, proper impedance matching, and warranty coverage.
Q: How do I verify cable integrity after installation?
A: Use RSLogix 5000 software to monitor redundancy status indicators. The system will flag communication errors if cable performance degrades.
Q: Is this cable compatible with 1756-RM redundancy modules?
A: No, the 1757-SRC1 is designed specifically for 1757-SRM modules. For 1756-RM modules, use the 1756-RMC1 cable.
Warranty & Support
All 1757-SRC1 cables include a 12-month manufacturer warranty covering defects in materials and workmanship. Our technical support team provides installation guidance and troubleshooting assistance throughout the product lifecycle.
