Product Technical Overview – ABB Bailey NTAM01 6637054A1 Infi 90 Analog Master Termination Unit
1. Product Description
The ABB Bailey NTAM01 6637054A1 is an Analog Master Termination Unit designed for use in the INFI 90® Distributed Control System (DCS). It facilitates proper interface between redundant IMAMM03 Analog Master Modules and associated slave thermocouple modules (such as NTAI02) or digital operator stations (NDIS01). This unit ensures signal integrity, provides cold junction compensation, internal calibration pathways, and organizes clean physical cable terminations for plant process inputs.
It is a passive circuit board mounted on an NFTP01 Field Termination Panel and acts as a central junction for analog input signals, calibration voltage, and communication lines.
