Delta AHACABC0-5A Extension Cable

Product Overview

The AHACABC0-5A (AHACABC0-5A) is a high-reliability extension cable designed for Delta's AH-series programmable logic controller (PLC) systems. Measuring 30.0 meters in length, this cable is engineered for connecting extension backplanes in distributed automation architectures. By providing a stable, interference-resistant link between the main processor and remote I/O modules, the AHACABC0-5A ensures deterministic data exchange across large-scale industrial control installations.

Technical Configuration

This cable is purpose-built for the Delta AH-series backplane interconnection standard. It allows for the flexible placement of I/O expansion racks, which is critical in modular machine designs and expansive plant floor layouts where the I/O nodes must be physically separated from the central control cabinet. The cable is designed to maintain signal integrity over its 30.0-meter span, ensuring that high-speed backplane communication remains robust against common-mode noise and electromagnetic interference typical in industrial settings.

Compatibility

The AHACABC0-5A is specifically designed for use with the following Delta AH-series backplane modules:

• AHBP04M1-5A

• AHBP06M1-5A

• AHBP08M1-5A

• AHBP12M1-5A

• AHBP06E1-5A

• AHBP08E1-5A

FAQs

Is it possible to daisy-chain this cable with others to increase the total length?

No. Backplane communication timing is strictly calibrated for specific cable lengths. Daisy-chaining cables beyond the manufacturer-specified length will introduce signal propagation delays, potentially causing communication errors or system instability. Always use the specified cable for the required distance.

What precautions should be taken when routing this 30-meter cable?

Because this cable carries high-speed backplane signals, avoid routing it alongside high-voltage power lines, VFD output cables, or heavy machinery motors. Maintain a minimum separation of 150 mm from high-power cabling to prevent electromagnetic interference from corrupting the PLC backplane data.

Installation Guidelines

• Cable Routing: When pulling the 30-meter cable through conduits or cable trays, avoid applying excessive tensile force, which can damage the internal shielding. Use a cable lubricant if the conduit path is complex, and ensure the minimum bend radius is maintained at all times to prevent internal conductor fatigue.

• Connection Integrity: Ensure the connectors are fully seated and the locking mechanisms are engaged on the extension backplane modules. Once connected, perform a visual inspection to ensure the cable is not under mechanical tension at the connector points.

• Noise Mitigation: If the cable must cross high-power lines, ensure the crossing is at a 90-degree angle to minimize the area of electromagnetic coupling.
