Frequently Asked Questions

• What types of sensors work with the SDIL-1608?
  The module accepts NAMUR-compliant proximity switches and loop-monitored signals.
• How does earth fault monitoring work?
  The system tests earth connection with 0.5 mA current and indicates status via dedicated LEDs.
• Can I use all 16 channels simultaneously?
  Yes, all 16 channels operate independently with individual monitoring.
• What is the response time of the input filter?
  The 100 Hz low-pass filter provides stable signal processing for safety applications.
• Do I need external power for sensors?
  No, the on-board DC/DC converter powers connected field devices.
• What is your return policy?
  We accept returns within 30 days for unused products in original condition.
