Frequently Asked Questions

• How does the broken wire detection feature operate on the 140DSI35300?
  The module monitors loop current thresholds and triggers a fault status when current drops below the minimum open-circuit limit.
• What are the key guidelines for selecting this model over standard input modules?
  Choose this variant when your application requires active wire-break diagnostics to ensure fail-safe sensor monitoring.
• Why does this module consume four input words instead of two?
  The extra address space accommodates the diagnostic data mapping required for individual channel wire-break monitoring.
• What triggers the red external fault LED on the front panel?
  The red LED lights up when an external sensor failure, power supply drop, or wire-break condition is detected.
• How can I verify communication health before rack startup?
  Ensure the green active bus communication LED remains steadily lit during power-up sequence.
