Honeywell MU-TAIL02 51304437-100 Analog Input FTA

Honeywell MU-TAIL02 51304437-100 Analog Input FTA

The Honeywell MU-TAIL02 51304437-100, also cataloged as the MU-TAIL02 Analog Input FTA, serves as a low-level analog input termination assembly for interfacing thermocouples, RTDs, and voltage/current signals within Honeywell TDC 3000 systems.

Hardware Specifications

Channel-to-Channel Isolation and Cold Junction Compensation

The MU-TAIL02 provides galvanically isolated inputs across all eight channels, ensuring minimal interference between thermocouple and RTD signals. Channel-to-channel isolation is reinforced by dielectric strength up to 1500 Vac rms. Cold junction compensation (CJC) is supported for thermocouple inputs, stabilizing measurement accuracy under varying ambient conditions. Common mode rejection ratio ≥120 dB suppresses induced noise across unbalanced leads.

Frequently Asked Questions

Q: What types of signals can the MU-TAIL02 accept? A: Thermocouple, RTD, voltage, and current signals are supported, with external power required for 2-wire transmitters.

Q: How is channel isolation achieved? A: Each input is galvanically isolated, with dielectric strength up to 1500 Vac rms.

Q: What resolution is provided by the A/D converter? A: The module digitizes signals at 15-bit resolution for high-precision acquisition.

Field Installation Guidelines

• Mount the FTA securely within designated termination slots.
• Use compression-type terminals for field wiring, applying correct torque to prevent loose connections.
• Ensure shielded cabling for thermocouple and RTD inputs, grounding at a single point to avoid circulating currents.
• Route analog wiring separately from high-voltage conductors to minimize induced noise.
• Verify polarity and continuity of each input channel before commissioning.
