Common Questions (FAQ)

• What is the difference between isolated and non-isolated inputs?
  Non-isolated inputs share a common reference point. They are cost-effective for group switching.
• Can I use this module with a 240V AC signal?
  No. The maximum on-state voltage is 132V AC. Exceeding this will damage the module.
• How do I power the module?
  It receives 5V DC power via the FlexBus from the communication adapter.
• What does the keyswitch position mean?
  The keyswitch (position 8) prevents installing the wrong module type in a terminal base.
• Is this module suitable for safety-critical applications?
  No. This is a standard control module, not a safety-rated device.
