Working Principle
RTD sensors produce resistance changes that vary with temperature. The MC-TAMR04 provides the field wiring interface for these low-level RTD signals and routes them to the paired low-level analog multiplexer processor module. The processor module scans the channels, conditions the signals, and converts them into digital temperature values for the DCS controller. The MC-TAMR04 does not perform measurement calculation by itself; it serves as the RTD field termination and signal interface.
Installation Requirements
- Confirm compatibility with the correct Honeywell low-level analog multiplexer processor module.
- Use appropriate RTD wiring practices, including three-wire or four-wire connections where required.
- Keep RTD wiring away from high-voltage power cables.
- Use shielded or twisted-pair cables where recommended.
- Label each RTD channel according to the instrument index.
- Verify grounding and shielding to minimize measurement noise.
- Perform channel checks after installation and configuration.
Precautions
- Do not connect high-level voltage signals to RTD terminals.
- Verify the paired processor module before installation.
- Avoid incorrect RTD wiring, as it can cause measurement errors.
- Do not exceed the terminal and module ratings.
- Replace the terminal assembly only after confirming system safety status.
- Confirm exact RTD types, channel count, and electrical ratings from official Honeywell documentation.
