Product Details
Product Description
The 1492-CABLE025X (also referred to by the catalog number 1492-ACS025C) is a heavy-duty, pre-terminated digital interface cable designed to facilitate the rapid connection between Allen-Bradley 1756 ControlLogix I/O modules and 1492 Interface Modules (IFMs). This cable eliminates the need for manual point-to-point wiring, significantly reducing commissioning time and minimizing the risk of cross-wiring errors in complex control cabinets.
Constructed with 20 individual conductors of 22 AWG wire, the 1492-CABLE025X provides the necessary signal density for standard digital I/O applications. One end of the assembly is equipped with a specialized 1756-TBNH Removable Terminal Block (RTB) connector, specifically designed to seat securely into ControlLogix 20-pin I/O modules, while the other end features a standard 20-pin connector for IFM integration.

Installation and Compatibility Note
The 1492-CABLE025X is optimized for digital signaling. While the original description mentions "Analog Connection Products," this specific part number is primarily used for discrete digital I/O due to its 20-conductor configuration and 1756-TBNH RTB compatibility. For analog applications requiring shielded twisted pairs, please verify against the specific module's wiring requirements.
Frequently Asked Questions
Can this cable be used with any 1756 I/O module?No, the 1492-CABLE025X is specifically designed for 20-pin ControlLogix modules that utilize the 1756-TBNH terminal block. High-density 36-pin or 40-pin modules require a different cable series.
What are the benefits of the 22 AWG conductor size in this assembly?The 22 AWG wire provides a balance between flexibility for routing through tight wire ducts and sufficient cross-sectional area to handle standard 24V DC digital signal currents without significant voltage drop over the 2.5-meter length.
