Honeywell MU-TAIHD2 High Input Analog/STI Input Terminal Assembly

Product Introduction

The Honeywell MU-TAIHD2 High Input Analog / STI Input Terminal Assembly is a critical field wiring interface module designed to connect high-density analog input signals to the Honeywell TDC 3000 and TPS (TotalPlant Solution) Distributed Control Systems. This terminal assembly serves as a physical interface between field devices (such as transmitters and sensors) and the corresponding analog input modules in the system’s control backplane.

Specifically built to support Signal Termination Interface (STI) configurations, the MU-TAIHD2 ensures secure, organized, and efficient wiring of multiple high-level analog signals, offering exceptional channel density, signal integrity, and diagnostic capabilities. This model is particularly suitable for environments requiring numerous analog signal connections, and where maintenance-friendly design and long-term reliability are critical.

FAQ

1. How many analog input channels does the MU-TAIHD2 support?
   It supports 32 independent analog input channels.

2. Is the MU-TAIHD2 compatible with the MU-PAIH03 analog input module?
   Yes, it is designed to interface directly with high-density analog input modules such as the MU-PAIH03.

3. Does the terminal assembly require external power?
   No, it is a passive component and does not require any external power supply.

4. Can shielded cables be terminated on this terminal assembly?
   Yes, it supports shield termination to maintain signal quality in noisy industrial environments.

5. Is the terminal block detachable for maintenance?
   Yes, the MU-TAIHD2 features detachable terminal blocks for convenient field maintenance and wiring checks.

6. What type of signal conditioning does the MU-TAIHD2 perform?
   None. It is a passive termination module and does not perform any signal conditioning or amplification.

7. Can this assembly be used with HART-enabled signals?
   Yes, as long as the paired analog input module supports HART communication, the terminal assembly passes the signal transparently.

8. Is there galvanic isolation between channels?
   No, isolation is handled by the connected analog input module, not the terminal assembly.

9. What is the typical wiring method used with MU-TAIHD2?
   Field devices connect via screw clamp terminals, while the assembly connects to I/O modules via ribbon cable.

10. Does the MU-TAIHD2 support hot-swapping of connections?
    The terminal blocks can be safely removed or inserted during maintenance when the system is in a safe state, but care must be taken to avoid signal disruption.
