Application Fields

The IS230SNCIH6A provides critical communication capabilities in power generation systems. In gas turbine installations, it interfaces with legacy protection relays, vibration monitoring systems, and fuel control valves using Modbus protocol. Steam turbine applications utilize this module for communication with governor systems and auxiliary controllers via DNP3.0.

Hydroelectric facilities deploy the IS230SNCIH6A to connect gate controllers and flow measurement devices to central control systems. The module’s multiple ports enable simultaneous communication with different subsystems, such as excitation control and bearing temperature monitoring. With ATEX Zone 2 certification, it operates safely in hazardous areas near fuel systems in combined-cycle power plants.
