Overview
The NTAI02 Thermocouple Input Termination Unit connects one or two IMASM02 slave modules through separate field cables.
Each unit receives up to 16 thermocouple or millivolt signals and sends them to the IMAMM03 master module efficiently.
Moreover, multiple NTAI02 units can be interconnected, allowing calibration voltages to route across eight IMASM02 units.
This flexible design ensures reliable signal acquisition and seamless integration within the INFI 90 process control system.
Key Features
The NTAI02 provides robust functionality for industrial thermocouple monitoring.
In addition, it includes internal and external test points for calibration verification and troubleshooting.
Main Features:
- Factory-wired connection to IMASM02 slave modules
- On-board terminal blocks for field input wiring
- Support for 16 thermocouple or millivolt inputs per unit
- Local cold junction reference for accurate temperature measurement
- Dedicated calibration socket with internal or external voltage source selection
- Easy installation into standard Field Termination Panel (NFTP01)

System Integration
The NTAI02 integrates directly with the IMAMM03 master and multiple IMASM02 slaves for accurate signal routing.
For instance, it ensures cold junction references and calibration voltages are shared among connected slave units.
Technicians can deploy the unit in complex process environments without compromising measurement accuracy or operational reliability.
Therefore, it is ideal for industrial plants requiring precise temperature monitoring and flexible system layouts.
