Product Short Description
Product Introduction
The ABB SPNIS21S+ is a high-performance network interface slave module designed for seamless integration into ABB’s Symphony Plus (Harmony Rack) and legacy Bailey INFI 90 / Net 90 distributed control systems (DCS). It serves as a critical communication bridge, enabling reliable, high-speed data exchange between the control network (Cnet/INFI-NET), system controllers, I/O subsystems, and higher-level Ethernet-based infrastructure via companion modules such as the SPIET800. This module provides robust network connectivity, advanced diagnostics, and industrial-grade reliability, forming the backbone of communication for large-scale process automation systems. It supports both legacy and modern system architectures, facilitating system upgrades and ensuring uninterrupted operation in demanding industrial environments.
