BAILEY NIAI03 Network Termination Module

The NIAI03 Network Termination Module from Bailey (Allen‑Bradley) is a Network 90 RTD analog input termination device that sits at the edge of a Bailey INFI 90 control network to terminate and condition RTD sensor signals, enabling stable, noise‑resistant temperature measurements along the Network 90 data path.

As part of the Network 90 termination family, the NIAI03 provides the necessary electrical terminations, shield considerations, and input conditioning for RTD input channels, helping to preserve signal integrity across long field runs and protecting the rest of the I/O chain on the INFI 90 architecture.

Designed for use within Bailey INFI 90 and Network 90 DCS environments, this module interfaces with other termination boards and interface modules to support temperature monitoring across complex process plants, including chemical, refining, and manufacturing facilities where precise RTD sensing is critical.

Common applications include accurate temperature measurement from RTD sensors in control loops, where the NIAI03 contributes to reliable data collection by providing correct termination and basic input conditioning required by the INFI 90 system, without altering the measurement signals beyond the intended termination behavior.
