Honeywell MC-TAOX02 51304476-175 Analog Output FTA

The Honeywell MC-TAOX02 51304476-175, also cataloged as the MC-TAOX02 Analog Output FTA, operates as a dedicated field termination assembly for 4–20 mA analog signal drive within Experion and TDC control platforms.

Hardware Specifications

4–20 mA HART Loop Protocol

The MC-TAOX02 supports standard 4–20 mA analog loop signaling for proportional control of valves and actuators. Channel-to-channel isolation is maintained through the FTA design, ensuring stable loop performance. Integration with HART-enabled devices allows diagnostic feedback and loop validation, while conformal coating provides environmental protection.

Frequently Asked Questions

Q: Does the MC-TAOX02 support redundant operation? A: No, this FTA is designed for non-redundant configurations only.

Q: What is the typical load compliance for the 4–20 mA outputs? A: Compliance is determined by the controller’s AO drive; the FTA provides termination and isolation only.

Q: Can the FTA be hot-swapped during operation? A: No, removal or insertion must be performed with the system powered down to maintain loop integrity.

Field Installation Guidelines

• Mounting: Secure the FTA within the designated cabinet slot, ensuring full connector engagement.

• Wiring: Route analog loop wiring separately from high-current conductors to minimize induced noise.

• Shielding: Ground cable shields at a single point to prevent circulating currents.

• Verification: Confirm 4–20 mA loop calibration during commissioning using a loop calibrator.

• Environmental Care: Ensure conformal coating remains intact; avoid exposure to solvents or abrasive cleaning agents.
