Working Principle
Field transmitters send analog signals such as 4-20 mA or 1-5 V DC to the MC-TAIH04 terminal assembly. The assembly routes these signals through its internal wiring interface to the paired high-level analog input processor module. The processor module then converts the analog signals into digital values for use by the DCS controller. The MC-TAIH04 itself does not perform control logic; it provides the physical and electrical interface between field instruments and the control system.
Installation Requirements
- Confirm compatibility with the paired Honeywell high-level analog input processor module.
- Verify signal type and wiring requirements for each channel.
- Use shielded cables for analog signals where required.
- Maintain proper separation between analog signal wiring and power cables.
- Ensure correct grounding to reduce noise and measurement error.
- Label each channel according to the instrument loop diagram.
- Perform loop checks after wiring is completed.
Precautions
- Do not connect incompatible signal types to high-level analog input terminals.
- Verify the paired IOP model before installation.
- Avoid short-circuiting signal terminals during wiring.
- Do not exceed the voltage and current ratings defined by the paired IOP.
- Replace terminal assemblies only after confirming system status.
- Final specifications must be verified from official Honeywell documentation.
