Industrial INNIS01 Symphony Network Interface Module

ABB Bailey INNIS01 Symphony Network Interface Slave Module is the Cnet interface front end for ABB INFI 90 and Symphony control systems, enabling real-time messaging across the control network. As a Network Interface Slave (NIS), it serves as the entry point for inter-node communication and terminates to a communications termination unit via NKLS cables, typically paired with an NTCL01 termination module. In standard configurations, the INNIS01 works with a Network Processing Module (for example INNPM12) to form the HCU interface that coordinates time-critical messages across the Symphony enterprise. The module is designed for ABB Symphony Harmony rack systems and carries the material designation YINNIS01 in ABB catalogs. Power is provided from +5 VDC and +15 VDC rails with a nominal consumption of about 10 VA. Common use cases include exchanging process data, alarms, and control commands between distributed nodes, enabling synchronized operation across INFI-90/Symphony deployments in industrial environments. This specific network interface component is intended to reside as part of the core control network hardware and integrates with termination units, network cables, and other Symphony hardware to ensure deterministic Cnet communications across the system.
