Allen-Bradley 1492-ACABLE080UA Pre-assembled I/O Cable

Configured for shielded analog signal transmission between PLC I/O assemblies and interface terminals in ControlLogix wiring architectures, the Allen-Bradley 1492-ACABLE080UA (1492-ACABLE080UA pre-assembled I/O cable) provides direct electrical execution. The cable assembly is factory-terminated for Bulletin 1756 analogue I/O, RTD, and thermocouple input module connectivity through the 1492 wiring system platform.

Suffix Breakdown & Model Matrix

The supplied documentation identifies the unit as a fixed catalog configuration. No additional suffix matrix or configurable option breakdown is specified for this model.

Hardware Specifications

EtherNet/IP Deterministic Signal Routing Characteristics

The 1492 cable assembly is intended for low-noise signal continuity between field termination hardware and ControlLogix analogue input modules. Shield continuity across the cable path reduces susceptibility to conducted electrical interference generated by adjacent motor feeders, VFD output conductors, and high-current switching devices.

Within Bulletin 1756 RTD and thermocouple input installations, the factory-terminated cable geometry maintains conductor consistency and minimizes terminal landing variation introduced during manual assembly. The assembly supports deterministic analogue signal transport by reducing wiring impedance variation between controller-side and field-side terminations.

Frequently Asked Questions

Q: Can the 1492-ACABLE080UA be connected or disconnected while the associated I/O module remains energized?
A: The cable itself contains no active circuitry, but connection or removal under energized conditions should follow the controller and terminal base hot-swap procedures defined for the associated Bulletin 1756 I/O hardware.

Q: What is the function of the cable shield in analogue and thermocouple applications?
A: The shield provides attenuation of externally induced electrical noise and should be bonded according to the grounding method specified for the associated analogue input module and panel grounding scheme.

Q: Is field termination required on this cable assembly?
A: No. The assembly is supplied with factory-installed connectors intended to reduce manual conductor termination and associated wiring variation.

Field Installation Guidelines

• Route analogue cable assemblies separately from AC motor feeders, contactor wiring, and VFD output conductors.

• Maintain shield continuity through the designated grounding point defined by the control cabinet grounding architecture.

• Avoid excessive bend radius near connector transitions to prevent conductor stress at molded termination points.

• Verify connector keying and pin orientation before insertion into Bulletin 1756 interface hardware.

• Do not pull the cable assembly by the connector housing during cabinet installation or maintenance procedures.

• Inspect cable shielding and outer PVC insulation for compression damage before energizing the control panel.
