Description
Product Overview
The NTR002-A is a precision temperature acquisition module developed for ABB distributed control environments, including Symphony Plus and INFI 90 systems. It is engineered to translate low-level sensor signals from RTDs and thermocouples into high-resolution digital data for process monitoring and control applications.
The module is designed for installation within control cabinets where stable measurement performance and long-term signal integrity are required under continuous industrial operation.
Functional Description
This interface module processes analog temperature signals from multiple sensor types and converts them into digital values for the control system. It supports both resistance temperature detectors and thermocouple inputs, allowing flexible deployment across different measurement points.
Signal conditioning, linearization, and conversion are performed internally to ensure stable and accurate temperature representation under varying process conditions.

Frequently Asked Questions
Q1: Can this module accept both RTD and thermocouple inputs simultaneously?
Yes. Each channel supports configurable sensor types depending on system setup.
Q2: Does the module require calibration after installation?
No field calibration is typically required, as signal conditioning is handled internally.
Q3: Is it suitable for high-temperature industrial environments?
Yes. It is designed for extended operation across a wide industrial temperature range.
Q4: Does it perform signal conversion externally or internally?
All signal conditioning and A/D conversion are performed within the module.
