Professional FAQs

• What is the maximum current per output?
  Each output handles 1.5A at 30°C or 1.0A at 55°C ambient temperature.
• Can I parallel outputs for higher current?
  No. Do not parallel outputs as it may cause uneven current sharing.
• What type of loads can this module drive?
  It can drive resistive, inductive, and lamp loads within specified ratings.
• Is external protection required for inductive loads?
  Yes. Use suppression diodes for DC coils and MOVs for AC coils.
• How do I calculate heat dissipation for my application?
  Multiply total output current by output voltage drop for approximate heat generation.
