Product Introduction
The ABB Bailey NCIS02 (6637087B1) is a Control I/O Slave Module used in the INFI 90 Distributed Control System (DCS) architecture, playing a critical role in handling data acquisition and command transmission between field-level input/output points and the central processor.
Designed for demanding industrial environments, the NCIS02 module facilitates seamless communication with I/O devices by distributing processing workloads and supporting efficient system expansion. It helps balance real-time control responsibilities across a distributed network, enhancing system resilience and response time.
The NCIS02 is a rack-mounted slave module, typically used in coordination with ABB’s Multifunction Processors (IMMFx series) and communicates using ABB’s proprietary INFI-NET protocol. Its reliable operation and wide compatibility make it a core component in many long-standing and large-scale process control installations.

Frequently Asked Questions (FAQ)
1. What control systems is the NCIS02 compatible with?
The NCIS02 is fully compatible with ABB’s INFI 90 and Symphony DCS platforms, allowing direct integration into existing infrastructures.
2. What distinguishes the NCIS02 from the NCIS01?
The NCIS02 is a later revision with improved internal communication handling and enhanced noise immunity. Functionally, it maintains compatibility with the NCIS01 but is considered more robust.
3. How does the NCIS02 communicate with the system’s CPU?
The module uses INFI-NET protocol to relay data between field I/O devices and the central Multifunction Processor (such as IMMFP12).
4. Can the NCIS02 handle both analog and digital signals?
Yes. It serves as a slave interface and works in tandem with analog (e.g., IMASI23) and digital (e.g., IMDSI13) I/O modules.
5. Is the NCIS02 hot-swappable?
No. Power must be disconnected before installing or removing the module to prevent damage or data faults.
6. What are the built-in diagnostic features of the NCIS02?
It includes LEDs for Power, Communication, Module Health, and Fault status, offering immediate visual feedback for field engineers.
7. What environmental tolerances does the NCIS02 support?
It operates in 0°C to +60°C and up to 95% non-condensing humidity, with robust vibration and EMI resistance.
8. Does the NCIS02 require configuration software?
No configuration is done on the module itself. Configuration is managed via the system controller (e.g., IMMFP12) using ABB’s control engineering tools.
9. Can I upgrade from NCIS01 to NCIS02 without changing the rack or backplane?
Yes. The NCIS02 is a drop-in replacement in most existing installations using the same rack and power supply.
10. What is the expected operational lifespan of the NCIS02 in industrial conditions?
When properly maintained, the NCIS02 can function reliably for over a decade, often exceeding 15 years in continuous operation.
