ABB Bailey NTR002-A Temperature Sensor RTD Interface Module

Description

The ABB NTR002-A is a dedicated temperature sensor interface engineered for the Bailey INFI 90 and Symphony Plus control platforms. It acts as a high-precision bridge between field-mounted Resistance Temperature Detectors (RTDs) and the system's input processing logic. This module is essential for converting low-level resistance signals into accurate digital data, ensuring reliable thermal monitoring for boilers, turbines, and chemical reactors. By providing specialized signal conditioning and noise rejection, the NTR002-A maintains tight process control in demanding industrial environments.
