Allen-Bradley 1492-CABLE025X Pre-Wired Digital Cable

Allen-Bradley 1492-CABLE025X Pre-Wired Digital Cable The Allen-Bradley 1492-CABLE025X serves as the primary 1492-CABLE pre-wired digital cable utilized to execute controller-to-terminal block signal transmission across ControlLogix I/O connection platforms. Hardware Specifications Parameter Specification Model 1492-CABLE025X Brand Rockwell Automation Allen-Bradley Product Type Pre-Wired Digital Cable Cable Length 2.5 m (8.2 ft) Conductor Count 20 conductors Wire Gauge 22 AWG Connector Type 20-pin connector Terminal Interface 1756-TBNH connector Signal Category Digital I/O Weight 2.07 lbs Dimensions Not specified in supplied data Operating Temp Not specified in supplied data Power Consumption Passive cable assembly; no independent power consumption Origin United States EtherNet/IP Deterministic Signal Routing The cable assembly is designed for fixed-point digital signal transfer between controller hardware and remote termination structures using preassigned conductor mapping. The 20-conductor layout maintains stable channel continuity during modular I/O cabinet installation. Pre-wired construction reduces manual termination points inside the enclosure and minimizes conductor identification variability during maintenance replacement. The 1756-TBNH interface format supports direct integration with compatible terminal block assemblies used in ControlLogix environments. Cable routing practices influence deterministic network behavior where parallel installation adjacent to motor feeders, contactor switching circuits, or VFD output conductors may introduce coupled electrical interference into adjacent digital channels. Frequently Asked Questions Q: Does the 1492-CABLE025X require field-side pin assignment during installation? A: No. The assembly is supplied as a factory pre-wired cable with fixed conductor mapping between connector interfaces. Q: Can the cable be installed in the same wiring duct as AC power conductors? A: Segregated routing is recommended. Digital signal cables should remain physically separated from high-current AC conductors and variable frequency drive output wiring. Q: Does the cable contain active signal conditioning electronics? A: No. The unit functions as a passive interconnect cable assembly without onboard electronic processing or signal conversion hardware.
