Frequently Asked Questions (FAQ)

• Q: How many output points does the 1746-OA8 module have?
  A: The 1746-OA8 provides eight (8) individual AC output points.
• Q: What is the main difference between the 1746-OA8 and the 1746-OA16?
  A: The key difference is the number of channels and current per point. The 1746-OA8 has 8 outputs at 1.0A each, while the 1746-OA16 has 16 outputs at 0.5A each.
• Q: What is the maximum current for the entire module?
  A: The total module current should not exceed 8.0 Amps at 30°C, shared across all eight outputs.
• Q: Can this module handle motor inrush currents?
  A: Yes, each output is protected for surge currents up to 10A for 25 ms, suitable for many inductive loads like small motors.
• Q: What is your return policy?
  A: We offer a 30-day return window for items in new, unused condition with original packaging.
