What is the maximum KYZ cable length that can be used for an 8600 meter?

Title
Maximum KYZ Cable Length for ION 8600 Meter

Language
English

Issue
Users want to know the maximum KYZ cable length that can be used with an ION 8600 meter.

Product Line
ION 8600

Note: ION 8600 is a discontinued, legacy meter. For new installations or replacements, Schneider Electric recommends using currently supported ION meter models such as the ION9000 series.

Environment
KYZ pulse output wiring
Energy pulse integration with external receiving devices

Cause
KYZ pulse signaling does not have a fixed maximum cable length because signal integrity depends on multiple electrical and installation variables rather than the meter alone.

Resolution
There is no fixed or published maximum KYZ cable length for the ION 8600 meter.

The achievable cable length depends on factors including, but not limited to:

• Cable type and characteristic impedance
• Output voltage and current levels
• Pulse width (duration) configuration
• Sensitivity and input requirements of the receiving device
• Noise environment, shielding, and grounding practices

For longer cable runs, use appropriate cable types (such as shielded twisted pair), ensure proper grounding, and configure pulse widths suitable for the receiving device. Always verify the input specifications of the connected equipment to determine acceptable cable length and ensure reliable pulse detection.

For new projects or meter replacement, use a supported ION meter platform (for example, the ION9000 series), which provides modern hardware, ongoing support, and current documentation.
