NT850 Main Steering System Configurations

All SOLAS/Class rated vessels are required to be fitted with Main and Backup Steering facilities and components which have been Approved and Certificated commensurate with relevant flag and Classification Society performance and reliability standards.

Accordingly, all Main Steering System components designed & manufactured by Navitron Systems Ltd. have been fully Classification Society Approved (DNV GL, ABS, RMRS, RRR etc.) and may be configured for complete Main Steering console configurations and/or stand alone component use as appropriate.

Whilst a typical Main Steering console might comprise Full Follow Up, Non Follow Up and Override Steering Controls etc. the final content can be chosen to suit the Steering System(s) involved (single or dual rudder, SOLAS or Non SOLAS etc.) thus a modular and cost effective range of Steering Control Panel variants are available.

Type 10 - SOLAS compliant Remote Control Panel for use with Main & Others (Types 8 & 9).

This modular aspect also extends to associated electronic elements which may be required to complete Steering System Configuartions (Steering Amplifiers etc.) in addition to Heading Control (Autopilot) and Analogue Heading Indication (Gyro Repeaters).

All NT850 electronic Main Steering System configurations are suitable for direct connection to nominal 24Vdc or 110/230/440Vac power supplies (derived from existing main steering gear Starter Boxes) via optional NT850 Power Supply Units.

Fully comprehensive set up facilities are included to provide immediate compatibility with all Steering System types therefore standard Navitron NT850 Steering Amplifier outputs include bang/bang switchlines for simple solenoid control in addition to +/-10Vdc and 4-20mA signals for proportional valves etc.

Navitron Sales and Application Engineering Personnel will be pleased to assist with Steering System Configuration recomendations and a dedicated Steering System Checklist is available for download in word format for initial submission.
