Expert Frequently Asked Questions (FAQ)

How does the 2 x 8 channel design impact wiring logic?
The split architecture allows you to isolate sensor groups or power domains across different connectors, reducing the need for external terminal blocks.

Are there specific selection criteria for the 1-pin versus 3-pin connector versions?
Select 1-pin connectors for minimal space applications; choose 3-pin versions if you require local ground/shield termination directly at the module input.

Can I swap the KM1002 while the I/O system is powered?
The pluggable interface supports fast disconnection, but always verify your specific controller's hot-swap policy before disconnecting active field signals.

What is the primary indicator of a failed input channel?
If the sensor is active but the status LED remains dark, check the connector seating and confirm the field voltage is within the 15-30 V DC range.

When should I prioritize the KM1002 over a standard high-density terminal?
Choose this module when your machine design demands field-side serviceability, as the pluggable connectors allow for "cable-harness" maintenance rather than individual wire removal.
