What Is the ABB INNPM22 Network Processor Module?
When your industrial control system demands reliable network communication within the Symphony Infi 90 architecture, the ABB INNPM22 Network Processor Module delivers essential connectivity. This module acts as a communication gateway, managing data exchange over the Infinet network. Designed for demanding environments, the INNPM22 ensures your distributed control system operates with minimal latency and high data integrity.
Part of the ABB Symphony Infi 90 series, the INNPM22 is built for long-term service in process industries such as power generation, oil and gas, and chemical manufacturing. Its compact form factor fits seamlessly into existing cabinets, reducing upgrade complexity.
Technical Specifications Breakdown
Understanding the key parameters of the INNPM22 helps you evaluate its fit for your system:
- Product Net Depth / Length: 73.66 mm – This shallow depth allows installation in space-constrained enclosures.
- Product Net Height: 360.68 mm – The height ensures compatibility with standard Symphony Infi 90 rack slots.
- Product Net Width: 279.4 mm – Provides ample surface area for heat dissipation and connector access.
- Product Net Weight: 0 kg – The listed weight is nominal; actual shipping weight includes packaging. The module itself is lightweight, simplifying handling.
- Battery Type: Button Cell – A single lithium button cell (5 g) maintains configuration memory during power loss, ensuring quick recovery.
- Battery Chemical Composition: Lithium – Offers long shelf life and stable voltage output for memory retention.
These specifications confirm the INNPM22 is a low-power, space-efficient module suited for continuous operation in control cabinets.
Industry Applications
Power Generation Plants: In turbine control systems, the INNPM22 processes network data from multiple remote I/O racks, coordinating real-time monitoring and protection logic. Its robust design withstands electrical noise and temperature variations common in power houses.
Oil and Gas Refineries: For distributed control of pipelines and processing units, the module handles high-speed data traffic between controllers and operator workstations. The lithium battery backup ensures no loss of configuration during maintenance shutdowns.
Chemical Manufacturing: The INNPM22 integrates with existing Symphony Infi 90 hardware to manage batch processes, providing reliable communication for critical safety interlocks and sequence control.
Installation and Setup Guidance
Mount the INNPM22 into a standard Symphony Infi 90 rack by aligning it with the backplane connector and securing it with the provided screws. Ensure the rack power supply is off during insertion to prevent damage. Connect the Infinet cable to the front-panel port, observing proper termination and grounding practices. After power-up, verify the module's status LEDs indicate normal operation. No field wiring is required beyond the network connection.
Maintenance and Reliability
The INNPM22 requires minimal routine maintenance. Inspect the module annually for dust accumulation and ensure ventilation paths remain clear. The lithium button cell typically lasts several years; replace it when the system indicates low battery or during scheduled outages. Avoid exposing the module to excessive vibration or corrosive atmospheres. Regular firmware updates, if available, can enhance network performance and security.
Compatibility and Integration
This module is designed exclusively for ABB Symphony Infi 90 systems using the Infinet communication protocol. It interfaces with Infi 90 controllers, I/O modules, and operator interfaces. The INNPM22 is not compatible with other ABB control platforms (e.g., 800xA) without additional gateway hardware. Verify your system's backplane revision and power supply capacity before installation.
Selection Guide and Purchasing Advice
Before ordering the INNPM22, confirm your existing system uses the Infinet network and that your rack has an available slot. Check the module's revision level against your system's compatibility list. SpareTechPLC stocks genuine ABB INNPM22 modules with full traceability. We recommend ordering a spare unit to minimize downtime in critical applications. Contact our technical team for assistance with configuration or integration questions.
Troubleshooting and Common Issues
If the module fails to communicate, first verify the Infinet cable is securely connected and undamaged. Check the backplane power supply voltage; the module requires stable DC power from the rack. A flashing fault LED often indicates a configuration mismatch or battery failure. Replace the button cell if the module loses settings after power cycles. For persistent issues, consult the Symphony Infi 90 system manual or contact SpareTechPLC support.
