Installation & Integration Solutions

This pre-wired cable simplifies system integration by connecting directly between 1756 digital I/O modules and 1492 interface terminal blocks. The color-coded wiring and keyed connectors prevent mis-wiring, while the flexible cable jacket allows easy routing through cable trays and conduit. Compatible with both DC sink/source and AC I/O modules, the 1492-CABLE-025Y supports 16-point and 32-point configurations.

Common Technical Questions

Q: Is this cable compatible with all 1756 digital I/O modules?
A: Yes, the 1492-CABLE-025Y works with all Allen-Bradley 1756 series digital input and output modules, including DC sink/source and AC I/O variants. Verify your specific module model for connector compatibility.

Q: Can I use this cable in a Class I, Division 2 hazardous location?
A: When installed per NEC Article 501 and used with appropriately rated I/O modules and enclosures, this cable is suitable for Class I, Division 2 applications. Always consult local electrical codes.

Q: What is the maximum current rating per conductor?
A: Each conductor is rated for the maximum current specified by the connected I/O module, typically 2A per point for DC modules and 1A for AC modules. Refer to module documentation for exact specifications.

Q: Does the cable include strain relief?
A: Yes, both connector ends feature integrated strain relief to protect against cable pull and vibration in industrial environments.

Q: Can I daisy-chain multiple cables for longer distances?
A: No, daisy-chaining is not recommended. For longer runs, select the appropriate cable length from the 1492-CABLE series (available in 0.5m, 1m, 2m, 3m, and 5m lengths).
