Overview
The ABB INNIS11 network interface module (part number 6644063B1, Rev B 1.1A) is a critical component designed for ABB’s Symphony and Harmony automation platforms. This Network Interface Slave Module (NIS) enables robust communication across distributed control systems by interfacing control units with the Infi-NET network. It acts as a communication gateway that facilitates real-time data exchange and control signal transmission between process control nodes, ensuring operational continuity in industrial environments.
Key Features
- High-speed Ethernet connectivity: Supports communication rates up to 100 Mbps for efficient data transfer and low-latency control operations
- Infi-NET compatibility: Purpose-built for ABB’s Infi-90 and Symphony platforms, enabling seamless integration with existing control hierarchies
- Compact form factor: Dimensions of approximately 90 x 90 x 30 mm with minimal weight (~0.1 kg) for flexible installation in control cabinets
- Low power consumption: Operates at less than 1.5 watts, reducing auxiliary power requirements and operational costs
- RJ45 Ethernet interface: Standard network connection supporting widely available industrial Ethernet infrastructure

Typical Applications
The INNIS11 is widely deployed in distributed control architectures where multiple process control units require coordinated network communication:
- Power generation and renewable energy systems (wind farms, hydro facilities)
- Oil and gas pipeline transmission and monitoring systems
- Chemical and refining process control networks
- Manufacturing and discrete automation with multi-node control hierarchies
- SCADA integration via OPC UA to third-party systems (Wonderware, Ignition)
- Industrial environments requiring secure, encrypted network communication (NERC CIP compliance)
Compatibility & Replacements
The INNIS11 functions as a Network Interface Slave Module within ABB’s Symphony ecosystem. Compatible platforms include ABB Symphony, ABB Harmony, and Bailey Infi-90 control systems. This module works in conjunction with other network interface components such as the INNISOL and INNPMII modules to form complete process control unit interfaces. For legacy Infi-90 deployments, the INNIS11 is a direct replacement where Infi-NET network communication is required. OPC UA support enables integration with modern SCADA systems and third-party industrial software, providing upgrade flexibility for aging control systems. Ensure that firmware compatibility and network configuration align with your existing Symphony or Infi-90 control architecture before deployment.
