Allen-Bradley 1492-CONCAB005X Conversion Cable Assembly

Allen-Bradley 1492-CONCAB005X Conversion Cable Assembly Configured for direct field wiring migration in ControlLogix systems, the Allen-Bradley 1492-CONCAB005X (1492-CONCAB005X Conversion Cable Assembly) provides physical and electrical interfacing between legacy PLC-5 or SLC I/O modules and 1756 series ControlLogix modules. The assembly preserves existing wiring topology while delivering shielded connectivity through standard RTBs. Hardware Specifications Parameter Specification Model 1492-CONCAB005X Brand Allen-Bradley Origin United States Weight 0.2 kg Dimensions Cable length 0.5 m (50 cm) Operating Temp -20 deg C to +80 deg C Storage Temp -40 deg C to +85 deg C Power Consumption 2 A per conductor Cable Type Shielded, multi-conductor Connector Type D-sub to ControlLogix RTB Voltage Rating 300 V Compliance UL, CE certified Industrial Control Features The cable assembly maintains backplane bus communication velocity licences when connected to ControlLogix modules. Shielding reduces EMI and ensures consistent signal integrity for deterministic Profinet/EtherNet/IP networks. It supports I/O density scaling by allowing multiple conversion cables within the same rack without interference. The assembly is compatible with firmware flash updates, ensuring proper signaling during migration from legacy PLC-5/SLC platforms. Frequently Asked Questions (FAQ) Q: Can the 1492-CONCAB005X cable be extended beyond 0.5 m? A: Extending the cable beyond the specified length may compromise signal integrity and backplane communication performance. Q: Is the cable suitable for repeated hot-swaps? A: The cable supports normal insertion/removal procedures, but frequent hot-swaps should be avoided to prevent connector wear. Q: Does the cable require additional shielding in high EMI environments? A: The factory shielded cable is sufficient for typical industrial settings. Additional shielding may be required only in unusually high EMI zones. Field Installation Guidelines Ensure chassis power is off prior to cable insertion. Align D-sub connector pins with RTB terminals to avoid bent pins. Route cable to minimize contact with high-voltage or high-current conductors. Secure cable with tie wraps or cable channels to prevent mechanical strain. Ground shields properly to panel backplane or chassis for optimal EMI protection. Verify connectivity before powering up the system to confirm signal continuity.
