NT921 MKII SMALL VESSEL AUTOPILOT Specifically
Specifically designed for small professional vessel use (typically 11-20m LOA) the NT921 MKII Autopilot provides a powerful combination of steering system control and interface facilities based on an extremely intelligent Control Unit which is clearly marked and simple to operate.
Accordingly, the NT921 MKII offers Navitron steering expertise in a robust and compact package which includes the following special features: –
A microprocessor based Autopilot for magnetically and GPS compass / track steered vessels from typically 10 – 20m (30 – 65ft).
Straightforward operation is a key feature of the NT921 MKII thus operator controls are kept to a minimum and are clearly identified by control panel markings which are red backlit for night viewing via a variable intensity illumination control.
A conventionally marked Course Selector permits simple course selection which is automatically corrected to maintain the vessel on a specified track when connected to a GPS or Track Plotter programmed with a track based on predetermined waypoints.
In addition to Track data, the NT921 MKII will also accept NMEA heading data directly from GPS compass systems etc. When dual heading inputs are employed (NMEA + mag sensor coil) the priority source is installation programmable with automatic changeover in the event of primary source failure.
Suitable for console or bracket mounting, the NT921 MKII Control Unit is intended for wheelhouse location and is supplied complete with Heading Sensor Coil and Rudder Reference Unit for installation to solenoid hydraulic systems (11-40Vdc/5A max).
High voltage solenoids (110/220Vac/dc) can also be accommodated via the inclusion of an optional Universal Relay Box type NT920URB.
Alternatively analogue signal control of water jets or analogue steering machines requiring -10v/+10v inputs can be configured via the inclusion of a Navitron Analogue Steering Interface (NT990ASI).
