Role in Genius I/O RTD Temperature Measurement
The IC660TBA021 provides the physical interface for RTD sensor leads and routes those signals safely to the associated electronics assembly (e.g., IC660EBA021). By separating the sensor wiring from the electronic circuitry, the terminal base:
-
Reduces noise and connection faults
-
Enables easier field terminations
-
Supports stable, high-quality analog signal capture
This architecture improves maintainability and minimizes downtime during installation and servicing.
