Details
Purpose: ABB SPNIS21 (also known as INNIS21) is a network interface slave module used to implement the Cnet communication interface in the ABB Symphony Plus system. As the front end of the Cnet communication interface, it is the intelligent link for communication between nodes in the network.
Applications:
Industrial automation: motor control, robotic systems, production line monitoring.
Process control: sensor signal processing in chemical industry, water treatment, energy management.
Hazardous environments: explosion-proof scenarios such as oil and gas, mining.
ABB SPNIS21Key features
High-speed data transmission: ABB SPNIS21 Provides high-speed Ethernet connection to ensure real-time performance, suitable for industrial environments that require fast data exchange.
Diagnostic function: ABB SPNIS21 Built-in diagnostic function helps with maintenance and troubleshooting, allowing users to detect and solve potential problems in time.
Human-machine interface: The panel is equipped with 16 LED indicators for error codes and event/error counts, and a status LED indicates the operating status of the module.
Safety: ABB SPNIS21 Provides electrical isolation to enhance the safety and stability of the system.
