ABB SPNPM22 Bailey INFI 90 Network Processor Module

Product Overview

The ABB SPNPM22 is a high-performance Network Processor Module (NPM) and Analog Input Module Processor (NIMP) engineered for the ABB Bailey INFI 90 and Symphony Plus Distributed Control Systems (DCS). It serves as a sophisticated interface that manages the acquisition of high-density analog signals while coordinating data flow within the system's communication loop.

Equipped with a 16-channel architecture, the SPNPM22 is designed to digitize standard industrial signals, including 4–20 mA current loops and 0–10 VDC inputs, with high precision. Its non-isolated design is optimized for environments requiring fast signal processing and robust integration with Bailey rack-mounted subsystems. The module features embedded diagnostics and a hot-swappable design, ensuring that maintenance in safety-critical sectors like power generation and petrochemical refining can be performed without process interruption.
