Allen-Bradley 1492-CONCAB005Y Pre-Wired Digital Cable

The Allen-Bradley 1492-CONCAB005Y serves as the primary 1492-CONCAB005Y Pre-Wired Digital Cable utilized to execute signal interconnection between 1771 and 1756 digital I/O platforms across ControlLogix automation platforms. The cable assembly incorporates a 1756-TBCH 36-pin front interface connector and a 25-pin D-shell male connector to provide direct module-to-interface-module wiring continuity.

The catalog number 1492-CONCAB005Y is presented as a fixed manufacturer part number. No official suffix breakdown or configurable model matrix is specified in the provided documentation.

Hardware Specifications

EtherNet/IP and I/O Density Integration Considerations

The 1492-CONCAB005Y supports high-density I/O migration by providing a predefined wiring path between legacy 1771 field terminations and 1756 ControlLogix digital I/O modules. The cable itself does not participate in EtherNet/IP communication or backplane data processing. Its function is limited to physical signal transfer between interface hardware, reducing terminal-point wiring complexity within high-channel-count control cabinets.

Frequently Asked Questions

Q: Does the 1492-CONCAB005Y require field termination of individual conductors?
A: No. The assembly is supplied as a pre-wired cable with factory-installed connectors at both ends.

Q: Does the cable consume backplane power from the ControlLogix chassis?
A: No. The cable is a passive interconnection device and does not draw power from the chassis backplane.

Q: Can the cable be connected or removed while modules are energized?
A: The supplied documentation does not specify hot-swap operation. Standard industrial practice is to de-energize associated modules before connecting or disconnecting cable assemblies.

Field Installation Guidelines

• Verify compatibility between the installed 1756 I/O module and the associated 1492 Digital Interface Module before connection.

• Confirm connector orientation before insertion to prevent pin damage.

• Route the cable separately from motor power wiring, VFD output cables, and other high-noise conductors.

• Maintain adequate bend radius throughout the cable run and avoid mechanical strain at connector terminations.

• Inspect connector retention hardware and ensure full engagement before system energization.

• Verify that the connected circuit current does not exceed 2 A per pin or 12 A per module.
