Bailey 6635700A1 Analog Input Termination Unit PLC Module

Bailey NTAI04 Analog Input Termination Unit, PN 6635700A1 (ZZ2), is a 16-channel RTD analog input termination module designed for Bailey INFI 90 and Net 90 control systems. This single‑board unit mounts in a standard Field Termination Panel (NFTP01), providing on‑board terminal blocks for field wiring, input‑channel transient and surge protection, and termination for 16 three‑wire RTD inputs; a single NTAI04 can terminate two analog slave modules (IMASM03/IMASM04) via connectors P1 and P2, with calibration performed on‑board through connector P3 using precision resistors. Terminated signals pass through the slave modules to the Analog Master Module (IMAMM03) for processing, enabling scalable RTD sensor interfaces within the INFI 90/Net 90 architecture.
