Precision Millivolt Processing
Engineered to accurately process extremely low-voltage signals with minimal thermal drift, ensuring stable temperature measurement in demanding environments such as boilers, turbines, and reactors.
Integrated Cold Junction Compensation (CJC)
Built-in temperature sensing compensates for ambient variations at terminal points, maintaining thermocouple accuracy despite changes in cabinet temperature.
Effective Common-Mode Rejection
Advanced signal filtering minimizes electrical noise and ground loop interference, preserving measurement integrity in electrically noisy industrial environments.
High-Density Sensor Integration
The 16-channel multiplexed architecture enables multiple temperature inputs to be handled through a single processor interface, reducing hardware costs and simplifying system design.
USA Manufacturing Quality
Manufactured to stringent U.S. industrial standards, ensuring durability, long service life, and reliable operation in harsh process plant conditions.
Does this module support both RTDs and thermocouples?
Yes. The MU-TAMR03 supports both sensor types, but proper configuration (software settings and jumpers) must match the specific sensor type being used (e.g., Type K thermocouple or Pt100 RTD).
Is this a brand new or refurbished component?
It is 100% brand new and original, supplied in factory-sealed anti-static packaging with full OEM traceability.
How does multiplexing affect the update rate?
Multiplexing allows multiple channels to share a common processing path, resulting in a slightly longer scan cycle compared to dedicated input modules. However, it remains suitable for standard process temperature control loops.
Can I replace a MU-TAMR02 with this MU-TAMR03 model?
In many TDC 3000 environments, the MU-TAMR03 is backward compatible with earlier revisions. However, system hardware and software compatibility should always be verified prior to replacement.
