Product Overview

The ABB NTR002-A serves as a high-precision, 2-channel temperature interface module designed for the S800 I/O family and Symphony Plus systems. This module converts low-level signals from industrial thermal sensors into high-resolution digital data for the DCS. It provides universal input support, handling both Resistance Temperature Detectors (RTDs) and Thermocouples (TC) with exceptional linearity. We supply this unit as 100% Brand New and Original, ensuring your critical thermal loops in power generation and chemical processing benefit from 16-bit conversion accuracy and robust galvanic isolation.

Technical Specifications

Engineering Advantages

• Universal Sensor Compatibility: The NTR002-A eliminates the need for separate RTD and Thermocouple modules. A single unit manages diverse sensor types, including platinum RTDs and high-temperature noble metal thermocouples (Types R, S, B), streamlining your spare parts inventory.

• High-Fidelity Signal Integrity: Utilizing a 16-bit high-precision converter, the module detects minute temperature shifts that standard 12-bit modules miss. This level of sensitivity proves vital for tight temperature control in reactor vessels and steam turbine monitoring.

• Extreme Thermal Resilience: While many I/O modules fail at 50 °C, the NTR002-A operates reliably up to +70 °C. This industrial-wide temperature rating permits installation in cabinets located near process heat sources without requiring supplemental forced-air cooling.

• Advanced Galvanic Isolation: Galvanic isolation between channels prevents ground loops and protects the system bus from high-voltage transients on the field side. This architecture ensures that a localized electrical fault on one sensor does not propagate through the entire DCS backplane.

FAQs

Does the NTR002-A support cold junction compensation for thermocouples?

Yes. The NTR002-A includes internal cold junction compensation circuitry to ensure accurate thermocouple readings. You can also configure external compensation via the S800 terminal base for even higher precision in environments with fluctuating cabinet temperatures.

How do I configure the module for different sensor types like Pt100 vs. Type K?

Configuration occurs through the ABB control software (e.g., 800xA, Symphony Plus, or Freelance). You select the specific sensor profile per channel in the I/O configuration hardware tree, and the module automatically adjusts its excitation current or gain settings.

Is this module hot-swappable in an S800 I/O rack?

The NTR002-A supports "Removal and Insertion Under Power" (RIUP) when used with compatible S800 active backplanes. This allows you to replace a unit without interrupting the power or communication of adjacent modules in the same cluster.

What protection features does the module include against wiring errors?

The unit features integrated over-voltage and over-current circuit protection. These safety layers prevent damage to the 16-bit converter if a field technician accidentally connects a higher voltage source to the signal terminals during commissioning.
