U.S. Navy Selects

Bailey Network 90 System

For New YTT Vessel

The U.S. Navy has selected the

Bailey Controls' Network 90® dis- tributed control system and field equipment for its YTT-9 Torpedo

Test Craft. The craft will perform acceptance tests for advanced un- dersea weapons systems. Network 90 will provide control, monitoring and alarm functions for critical ship machinery systems, including steer- ing, maneuvering, main propulsion, bilge and ballasting.

Among the purchased instrumen- tation are two custom consoles each using Network 90 Operator Inter- face Units (OIUs) to provide a dy- namic graphic "window" to vessel operations. The OIUs permit com- prehensive data collection and ma- nipulation, with alarm manage- ment, logging, trending and archival storage.

Control for the ship will be imple- mented through redundant micro- processor-based Network 90 Multi-

Function Controller modules. Each module can execute up to 128 user- configured control loops

Also included in the instrumenta- tion selection are the Bailey BC

Smart Transmitters which provide remote communication, continuous diagnostics and advanced calibra- tion features. Transmitter output can be programmed to be square root, linear or nonlinear of the mea- sured variable.
