FAQ

• Q: Can MTL4514 work with mechanical switches?
  A: Yes, but add 500Ω-1kΩ series and 20kΩ-25kΩ parallel resistors for LFD.
• Q: Max cable length for sensors?
  A: Depends on resistance—keep under 600Ω total.
• Q: Is phase reversal protection standard?
  A: Yes, selectable via onboard switch.
• Q: Relay lifespan?
  A: 100,000+ cycles at rated load.
• Q: Operating temperature range?
  A: -20°C to +60°C (T6 rated).
