Common Questions

  • Channels? 4 AI + 4 AO.
  • HART? Yes.
  • System? CENTUM.

Mounting Steps

  1. Install the module in the appropriate I/O nest or FIO base.
  2. Wire field transmitters and actuators observing polarity.
  3. Configure ranges and HART settings in the control system.
  4. Power up and verify input/output values.
  5. Confirm isolation and diagnostic status.

Buying Advice

  • Select when mixed AI/AO with HART is required in one slot.
  • Confirm KS cable adapter or terminal option if used.
  • Useful spare for CENTUM analog mixed I/O positions.
