The NTAI06 is a 16-channel analog input termination unit designed to terminate field wiring in process control applications. It consists of a single printed circuit board that mounts directly in an NFTP01 Field Termination Panel.
The unit routes analog field signals to compatible slave modules, including the IMASI03, as well as the IMMFP01, IMMFP02, and IMMFP03 Multi-Function Processors.
Each channel can be configured independently for several analog input types, including differential voltage, single-ended voltage, system-powered or externally powered 4–20 mA current loops, thermocouples, millivolt signals, and 3-wire RTDs.
Integrated cold junction reference RTDs provide thermocouple compensation. On-board transient and surge protection helps maintain signal integrity and protect connected system components.
Supports up to 16 independent analog input channels
Accepts 12 to 22 AWG field wiring
Uses on-board compression fitting terminal blocks
Provides per-channel signal configuration through on-board jumpers
Includes individual fuses for system-powered 4–20 mA input channels
Includes cold junction reference RTDs for thermocouple compensation
Provides input channel transient and surge protection
Connects to slave modules through NKAS01 or NKAS11 shielded cable assemblies
Supports cable lengths up to 60 meters (200 feet)
Mounts directly in an NFTP01 Field Termination Panel
INFI 90 process management system field signal termination
Distributed Control System analog input routing
Multi-channel temperature monitoring
Process variable measurement and monitoring
Thermocouple, RTD, voltage, and current signal termination

Wear a static-grounding wrist strap when handling the termination unit.
Use a static-dissipating work surface when working with exposed electronic circuitry.
Disconnect cabinet power and I/O power before wiring or servicing the unit.
Remove assigned slave modules or termination modules before installing connecting cables.
Insert the termination unit tabs into the outer edge slots of the NFTP01 panel.
Secure the unit using two No. 10 screws.
Install the chassis ground using a No. 10 self-tapping screw and an external star lock washer.
Configure channel jumpers J1 through J64 for the required voltage, current, RTD, or thermocouple input type.
Complete all jumper configuration before applying power.
Secure the RTD cover over the terminal blocks when thermocouple inputs are used.
Correct RTD cover installation is required for accurate cold junction compensation.
Connect power wiring using 14 AWG wire.
Connect E1 to the +24 VDC supply.
Connect E2 to the DC bus bar or I/O COM connection.
