NT990RTU Provides 2 isolated digital outputs and 1 non-isolated analogue output to external equipment such as VDR/SVDR etc.
Suitable for direct connection to 11-40Vdc ship’s supply.
The Rudder Angle Indication system is separate to the steering system and is for indication only. It is an IMO requirement to have this system independently from the steering control system. Rudder angle indication is required for each steering position and at the emergency steering position in the steering gear room.
The different regulatory bodies vary on the requirements on the Rudder Angle Indicators (RAI). DNV requires a second, independent rudder angle indication system on the bridge. Panama Canal regulation requires large instruments (192x192mm minimum) on the bridge wings, visible for the pulling train operators and the IMO/MED (ISO 20673) requires the accuracy of the system to be above 1 degree.
