Function and Working Principle
The MC-TAIH15 operates by receiving analog signals from field devices and converting them into digital values for the control system:
- Field instruments send analog signals (current or voltage).
- The module conditions and filters the incoming signals.
- Internal circuitry performs analog-to-digital conversion.
- Digital data is transmitted to the Honeywell controller.
- The control system uses this data for monitoring and automation decisions.
This ensures stable, accurate, and continuous process measurement.
