ABB NTR002-A Temperature Sensor Interface Module

Configured for two-channel temperature signal acquisition in ABB Bailey distributed control and process control systems, the ABB NTR002-A (NTR002 Temperature Sensor Interface Module) provides direct interfacing for RTD and thermocouple field devices. It converts temperature signals through 16-bit analog-to-digital conversion for control-system processing.

Hardware Specifications

Temperature Signal Acquisition

The NTR002-A accepts temperature measurements from RTD and thermocouple field devices through two input channels. The supplied data specifies a 16-bit analog-to-digital conversion stage and a measurement accuracy of +/- 0.1 deg C. The stated temperature measurement range is -200 deg C to 1800 deg C, with the applicable range dependent on the connected sensor type.

The module is identified for integration with ABB Bailey distributed control and process control architectures. Sensor selection and wiring must match the input channel requirements of the installed temperature measurement circuit.

Frequently Asked Questions

Q: How many temperature input channels does the NTR002-A provide?
A: The supplied specifications identify two temperature input channels.

Q: Which temperature sensor types are supported?
A: The supplied data identifies RTDs and thermocouples as supported sensor types.

Q: What is the analog-to-digital conversion resolution?
A: The module uses 16-bit analog-to-digital conversion according to the supplied specifications.

Field Installation Guidelines

• Verify the NTR002-A mounting position and mechanical dimensions against the actual assembly before installation. The supplied dimension entry contains mixed units and should be verified against the manufacturer's mechanical drawing.
• Confirm that the connected sensor type is compatible with the selected input channel before energizing the measurement circuit.
• Keep temperature sensor wiring separated from high-current power conductors and switching circuits where practical to reduce electrical interference.
• Route shielded sensor cables according to the installed ABB system wiring specification. Apply shield termination consistently with the control-system grounding scheme.
• Check terminal polarity and thermocouple lead identification before commissioning. Incorrect thermocouple polarity can produce an incorrect temperature signal.
• Verify the configured sensor type, engineering range, and channel assignment in the control-system configuration before placing the measurement loop into service.
• Do not use the supplied weight or dimensional information as a mechanical mounting reference where the physical assembly differs from the stated configuration.
