Description

The ABB Bailey NASM03 is a specialized Analog Slave Module belonging to the Network 90 series, primarily designed to interface with low-level Resistance Temperature Detection (RTD) signals. This unit serves as a critical signal conditioning layer, transforming raw thermal resistance data into high-level signals suitable for complex process logic. As a plug-in component for the Module Mounting Unit (MMU), the NASM03 integrates seamlessly into the system’s decentralized architecture, expanding the input capacity of the primary control nodes.

Applications

Large thermal power plants: Monitor turbine bearings, generator windings, and condenser temperature points.

Oil refineries: Track heat exchangers and reactor temperatures to keep processes within safe limits.

Steel and iron smelting plants: Collect RTD data from blast furnace cooling and heating systems.

Chemical processing plants: Control temperature loops in high-isolation environments to avoid interference.

Paper and packaging plants: Monitor drying and pulp process temperatures to improve product consistency.

Features

Accepts Low Level Resistance Temperature Detection (RTD) Signals

Standard Module, Single Slot

Processes up to Eight (8) Isolasted RTD Analog Input Signals

Installation

The Analog Slave Module Inserts Into a standard NETWORK 90 Module Mounting Un t (MMU) and occupies one slot. The Module is gulded by plastic rails and is fully Inserted when the front panel 18 flush with the top and bottom of the MMU rack and the latch engages into the MMU frame. To remove the module, release the latch by squeezing the bottom front plastic frame and pulling outward.

FAQ

Q: Does the NASM03 support analog inputs other than RTDs (such as thermocouples)?
A: Optimized for RTDs; thermocouples require other NASM or mixed-input modules.

Q: How many NASM03 slaves can one AMM manage?
A: Depends on bus bandwidth and scan cycle; one AMM can handle multiple NASM nodes.

Q: Does the NASM03 have cold junction compensation?
A: Not required for RTDs; it uses wire resistance compensation logic instead.

Q: After replacing the NASM03, is recalibration needed?
A: No. Calibration is stored in the host system; hardware swap is plug-and-play.

Q: Will the NASM03 work if +24 VDC is lost?
A: Communication may remain, but sensor reading becomes invalid without +24 VDC field power.
