Features:

  • Pre-Wired 1756-TBCH Integration Defeats Commissioning Delays
  • Heavy-Duty #18 AWG Multi-Conductor Core Safeguards Signals
  • Open-Architecture Flying Leads Provide Ultimate Adaptation
The Allen Bradley 1492-CABLE025TBCH features a factory-terminated 36-point removable terminal block that mounts natively onto ControlLogix digital modules. This completely eliminates manual pin-crimping, terminal sorting, and individual conductor label checking on the chassis end, shortening the labor overhead of panel construction by up to 75%.

Built with high-grade copper conductors across a 40-wire matrix, the Allen Bradley 1492-CABLE025TBCH provides exceptional cross-sectional electrical density. The #18 AWG gauge minimizes signal attenuation and resistance over 2.5 meters, ensuring crisp digital logic transitions and resilient operation when exposed to severe localized electromagnetic fields.

While the controller end of the Allen Bradley 1492-CABLE025TBCH is specialized for Rockwell chassis, the field end provides raw, color-coded flying leads. This gives engineers complete freedom to interface with generic terminal distribution strips, custom relays, barrier blocks, or third-party junction hardware without buying restrictive proprietary interfaces.

The 1492-CABLE025TBCH Allen Bradley ControlLogix Digital I/O Module-Ready Pre-Wired Cable may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
Engineered as a high-density wiring asset, the Allen Bradley 1492-CABLE025TBCH enables immediate, secure coupling to 36-point ControlLogix digital I/O modules. By deploying a factory-fused, pre-wired 1756-TBCH removable terminal block (RTB), it bypasses the traditional manual pin-out phase, providing system integrators with an uncompromised electrical path from the processor chassis directly to field marshalling panels.

Featuring a robust 40-conductor construction utilizing #18 AWG copper wire gauge, the Allen Bradley 1492-CABLE025TBCH optimizes signal continuity while minimizing voltage drops across its 2.5-meter span. The premium formulation of the outer jacket ensures substantial mechanical tensile defense, shielding internal control lines from the geometric stress, friction, and electromagnetic interference typical of high-density industrial control cabinets.

n critical automation commissions, manual wiring errors during RTB population pose significant diagnostic delays; the Allen Bradley 1492-CABLE025TBCH mitigates this risk via rigid factory quality controls. The integration-ready flying leads permit seamless adaptation to proprietary terminal interfaces or customized terminal blocks, preserving custom panel layout preferences while enforcing a highly organized, professional cabinetry aesthetic.

Beyond clean-slate installations, the Allen Bradley 1492-CABLE025TBCH serves as a vital tool during system upgrades, accommodating effortless conversion pathways from legacy Modicon 800 or Allen-Bradley 1771 PLC-5® platforms over to modern 1756 ControlLogix automation frameworks. This cross-generation adaptability preserves capital investments while accelerating factory floor modernization.

Technical notes
When installing the Allen Bradley 1492-CABLE025TBCH, note that out of its 40 total internal conductors, exactly 4 conductors are dedicated as "Not Connected" (flying leads end) to account for structural core balancing and spare routing paths. System engineers must verify that the field-side terminations map correctly to the standard 1492-series wiring table colors to maintain precise signal isolation across the 36 active lines mapped to the 1756-TBCH block.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which specific digital I/O modules are fully compatible with the Allen Bradley 1492-CABLE025TBCH?
The Allen Bradley 1492-CABLE025TBCH is designed to interface with 36-point digital I/O modules within the ControlLogix 1756 platform. Compatible input modules include the 1756-IA16I, 1756-IA32, 1756-IB16, 1756-IB16I, 1756-IB32, 1756-IH16I, 1756-IM16I, and 1756-IV32. Compatible output modules encompass the 1756-OA16I, 1756-OB8EI, 1756-OB16D, 1756-OB16I, 1756-OB16IS, 1756-OB32, 1756-OH8I, 1756-OV32E, 1756-OW16I, and 1756-OX8I.
How does the internal conductor layout of the Allen Bradley 1492-CABLE025TBCH map out relative to the 36 terminals on the 1756-TBCH arm?
The Allen Bradley 1492-CABLE025TBCH contains a total of 40 conductors, where 36 individual conductors are precisely bound to the corresponding numbered screw terminal positions (1 through 36) on the pre-wired 1756-TBCH connector. The remaining 4 conductors are left completely unassigned (Not Connected) at the flying lead bundle end, which serves as a safety tolerance or extension reserve for custom wiring modifications.
Does the Allen Bradley 1492-CABLE025TBCH include diagnostic signals or specialized parameter pins for firmware-level tracking?
No, the Allen Bradley 1492-CABLE025TBCH is a passive electro-mechanical interconnect system and does not contain microprocessor components or active firmware diagnostic monitoring. However, it fully carries deep diagnostic signals (such as wire-fault sensing, electronic fusing status, and short-circuit monitoring) from intelligent ControlLogix modules like the 1756-OB16D or 1756-OB8EI directly to field terminals without interference.
What is the conductor wire color coding convention applied across the flying leads end of the Allen Bradley 1492-CABLE025TBCH?
The Allen Bradley 1492-CABLE025TBCH utilizes Rockwell Automation’s standardized industry color code matrix for its 40-conductor lines to aid engineering identification. Leads 1 through 6 utilize solid base colors (Black, White, Red, Green, Orange, Blue), while pins 7 through 40 transition into complex dual and triple stripe combinations (e.g., White/Black, Red/Black/Green) to guarantee absolute clarity during field side commissioning.
What are the exact environmental limitations regarding temperature and humidity for deploying the Allen Bradley 1492-CABLE025TBCH?
The Allen Bradley 1492-CABLE025TBCH is rated for an insulation temperature threshold of up to 80°C (176°F). For storage and unpowered transport, it tolerates extreme environments ranging from -20°C to 80°C (-4°F to 176°F). The cable assembly operates reliably under non-condensing relative humidity bands between 5% and 95% RH and complies with standard industrial Pollution Degree 2 constraints.
Are there any specific safety certifications or hazardous location approvals verifying the Allen Bradley 1492-CABLE025TBCH for global trade?
Yes, the Allen Bradley 1492-CABLE025TBCH complies with stringent international quality metrics required by global engineering procurement. The cable assembly is officially CE marked, c-UL-us Listed (for the United States and Canada safety standards), and possesses FM (Factory Mutual) approval, confirming its structural integrity within safe-area industrial control enclosures.
