Expert FAQs

• How fast is the output response really?
  It's very fast. The turn-on delay is typically just 0.15 milliseconds. This speed is perfect for applications needing precise timing.
• Can I connect a small light directly to it?
  Yes. Each output can handle a lamp load up to 5 watts. It's great for pilot lights or status indicators.
• What happens if there is a wiring short circuit?
  The module has internal diagnostics. It can alert the PLC control system about external faults like missing power.
• Is it okay for use in noisy factory environments?
  Absolutely. The optical isolation between channels and the PLC bus greatly reduces noise problems.
• What's the best practice for long cable runs?
  Always use shielded cable for runs over 100 meters. This prevents signal issues and ensures reliable operation up to the 1000m maximum.
