Expert FAQs

• Q: Can I connect AC sensors?
  A: No – designed for DC switches/proximity detectors only
• Q: What’s the relay lifespan?
  A: 1 million operations at maximum load
• Q: How many MTL4220 detectors needed?
  A: Two – one per channel to maintain isolation
• Q: Can I disable LFD completely?
  A: Yes – via top-mounted configuration switches
• Q: Maximum cable length?
  A: Depends on resistance – keep below 800Ω per channel
