RTD Analog Input
Termination Unit
The ABB NTAI04 is an RTD analog input termination unit used in the Bailey INFI 90 architecture. It provides the field-side termination point for three-wire RTD signals and connects the field circuits with the associated analog slave-module arrangement.
A field termination unit built around the RTD signal path.
NTAI04 is part of the input-side hardware used to bring RTD temperature signals into the INFI 90 system. The unit is a termination interface, rather than the analog master processing module itself.
For maintenance, the termination unit should be assessed together with the field wiring, termination cable and associated slave module when tracing an abnormal temperature input.
Field measurement → termination → analog processing
The NTAI04 sits on the field termination side of the RTD input chain.
Three-wire resistance temperature detector and field circuit.
Terminates and routes the RTD field inputs toward the slave-module path.
Associated RTD analog slave modules form the documented module-side path.
Core NTAI04 parameters
Only fields confirmed in the manufacturer documentation are shown.
P1, P2 and P3 serve different purposes.
Connection points are treated separately from the general specification list.
Part of the first eight-input RTD slave-module connection path.
Part of the second eight-input RTD slave-module connection path.
Used in the documented calibration arrangement.
What brings customers to the NTAI04 page?
Focused on practical fault-isolation rather than repeating specifications.
When a temperature channel, channel group or termination path becomes unreliable, engineers may need to identify the exact termination unit before replacing the associated electronics.
Compatibility, historical replacement and substitution are different questions.
The NTAI04 manual describes the termination unit as providing the input/output connection between plant equipment and INFI 90 / Network 90 modules.
The cited NTAI04 manual does not identify a later drop-in successor. A migration decision therefore requires system-level verification.
A similar RTD termination unit should not be treated as interchangeable without checking connectors, cable, field wiring and associated modules.
Check the complete path before replacing the termination unit.
Inspection, packaging and warranty support.
Part number and requested quantity are checked before quotation and shipment.
Product identity and physical condition are inspected. Functional testing can be arranged where applicable.
Protective industrial packaging is used, with anti-static protection where appropriate.
AMIKON warranty covers verified product-related defects under the agreed warranty terms. DOA or transit cases are reviewed with evidence.
Five questions customers usually need answered first.
NTAI04 is an RTD analog input termination unit used in the Bailey INFI 90 / Network 90 architecture.
The manufacturer documentation specifies 16 three-wire RTD inputs.
The NTAI04 documentation references IMASM03 and IMASM04 as RTD slave modules associated with the termination unit.
Confirm the installed part number, termination panel, cable arrangement, associated slave module and field wiring.
Please provide Part Number, Quantity, Destination, Required Date, Machine and System Model.
