Honeywell MC-TDOY22 51204162-175 Digital Output FTA

Honeywell MC-TDOY22 51204162-175 Digital Output FTA

The Honeywell MC-TDOY22 51204162-175, also cataloged as the MC-TDOY22 digital output FTA, operates as a hardware termination assembly for discrete 24 VDC signal interfacing within Honeywell Experion PKS, TPS, and TDC 3000 control platforms.

Hardware Specifications

4-20 mA HART Loop Protocol and Channel Isolation

The MC-TDOY22 supports conditioned digital output interfacing with Honeywell subsystems, enabling deterministic passthrough for 4-20 mA HART loop signals when paired with MU-series output cards. Galvanic isolation ensures separation between control logic and field circuits, protecting system integrity and preventing cross-channel interference across the 16 discrete outputs.

Frequently Asked Questions (FAQ)

Q: How many channels are available on the MC-TDOY22? A: The module provides 16 independent digital output channels.

Q: What type of terminals are used for field wiring? A: Compression or screw-type terminals are provided for secure field connections.

Q: Does the module include environmental protection? A: Yes. The conformal coating protects against moisture, dust, and contaminants.

Field Installation Guidelines

• Mount the FTA in the designated Honeywell rack channel with full mechanical engagement.
• Wire outputs to solenoids, relays, or indicator lights using shielded cabling.
• Ground shielding at the system end only to prevent ground loops.
• Separate discrete output wiring from high-voltage conductors to minimize induced noise.
• Verify polarity and continuity before energizing circuits.
• Maintain ambient conditions within specified operating temperature and humidity limits.
