Product Overview
The ABB Bailey NASM02S is an analog slave module used in the INFI 90 Distributed Control System (DCS). As part of the Symphony Harmony/INFI 90 series, this module is designed to interface with various analog input/output (I/O) components and provide reliable signal conditioning, transmission, and data acquisition for industrial process control environments.
This module acts as a bridge between the field analog signals and the process control unit, translating real-world measurements such as temperature, pressure, and flow into digital signals that the control system can interpret and respond to efficiently.

Frequently Asked Questions (FAQ)
-
What is the main role of the NASM02S in the INFI 90 system?
It acts as an interface module that receives or sends analog signals between field devices and the master controller. -
Can NASM02S modules be mixed with digital I/O modules in the same rack?
Yes, as long as the rack supports the combination, analog and digital modules can coexist. -
How are analog ranges selected or configured in this module?
Signal ranges are selected through system configuration software and specific hardware jumpers (if applicable). -
Is the NASM02S suitable for safety-critical applications?
It is not certified for SIL or safety-instrumented systems but is commonly used in non-critical process controls. -
How does the module handle signal calibration?
Calibration is typically handled via software tools in the INFI 90 suite or manually calibrated in rare cases. -
Is redundancy supported with NASM02S modules?
Redundancy is handled at the system level; the module itself is designed for high reliability but not inherently redundant. -
Can this module operate in outdoor enclosures?
Only if the enclosure meets the required environmental and temperature protection ratings. -
What happens if a channel fails on the NASM02S?
The system diagnostics can detect failures, and the affected channel can be isolated or bypassed. -
Does it require any special firmware updates?
NASM02S is a hardware-based analog module and typically does not require firmware updates. -
How is this module maintained in large-scale installations?
Visual inspection, signal verification via HMI/SCADA, and occasional testing with simulators are standard maintenance steps.
