Frequently Asked Questions (FAQ)

• Q: What is the maximum count speed of the 1746-HSCE2?
  A: It supports an exceptionally high maximum input frequency of 1 Megahertz (1,000,000 pulses per second).
• Q: How many real outputs does this module provide for control?
  A: It provides four (4) real sourcing outputs capable of switching up to 1.0 Amp each.
• Q: Can I connect standard 24V industrial encoders to this module?
  A: Yes. The input supports a wide range from 10V DC to 30V DC, perfect for 24V encoder signals.
• Q: What is the difference between the real and virtual outputs?
  A: The four real outputs are physical terminals that switch power. The four virtual outputs are internal status bits used for logic within the controller.
• Q: Is this module in stock and what is the delivery time?
  A: Yes, we have it in stock. Orders are processed and shipped within 5 business days.
