FAQ

• What is the output signal range?
  Configurable from 0 to 21.0 milliamps, supporting standard 0-20mA and 4-20mA loops.
• What does "group isolation" mean?
  Channels 1-4 are isolated from channels 5-8 and from the logic side by 500VDC, preventing ground loops and interference.
• How is output accuracy verified?
  The module provides output verification feedback to the controller, confirming the actual current being delivered.
