FAQ

• How many channels does it have? 2 independent isolated channels.
• What output signals are supported? 4–20 mA or 0–10 V DC.
• Does it support redundancy? Designed primarily for non-redundant low-density applications with high isolation requirements.

Installation Guide

1. Install the isolator in a compatible MC series chassis or IOTA position.
2. Connect the controller-side signals according to the system wiring diagram.
3. Wire the field devices to the isolated output terminals (observe polarity for current loops).
4. Apply power and verify isolation and signal integrity.
5. Perform loop checks and calibration as required by site procedures.

Selection Tips

• Select when galvanic isolation is required for analog outputs in MC series systems.
• Confirm 2-channel density meets application needs.
• Verify compatibility with the specific Experion or TPS configuration.
