FAQ

• Q: Can I use regular switches without resistors?
  A: No – switches require external resistors for LFD
• Q: What’s the hysteresis value?
  A: 200μA (650Ω) prevents relay chattering
• Q: Maximum switching frequency?
  A: 250Hz at full contact rating
• Q: Is spark suppression included?
  A: Yes – internal for inductive loads
• Q: Humidity tolerance?
  A: 0-95% non-condensing operation
