Autopilot Yokogawa PT500

autopilot yokogawa pt500


The PT500 autopilot conforms to the technical requirements for the performance standard determined by IMO resolution A342 and meet type approval issued by Class NK (Approval No. KF96EQ-001).

It is available in two versions. The PT500A - Adaptive and the PT500D - Digital Autopilot, which differ in the respect of the method of auto steering. You can freely select a suitable model and configure the optimum system for the type of vessel concerned.

 Product Detail: 

The Steering Stand design is suitable for standing or sitting positions based on the ergonomic principles of height (11244mm).

Aseparate unit is used for each purpose allowing for excellent functional expandability and operability. However, all components within the stand can easily be incorporated into a panel and cockpit bridge console due to their compact design which is about 80% smaller when compared with our preous models.

In addition to the independent follow-up circuit, the automatic and hand steering control systems are also independent of each other.

A course setting dial (25 0/r) has been incorporated along with its associated set course indicator utilizing high intensity red LED Displays.

The function keys are easy to use and understand with pictorial characters for every function to help reduce the possibility of an incorrect/accidental command.

In addition, we have provided two heading input circuits. Thus by allowing a secondary heading signal from an external magnetic compass or DGPS. This provides a back up to the heading signal generated by the Gyrocompass. The PT500 can also track and route information feed from either a DGPS, INS or ECDIS System.

The PT500 includes three different modes of the course keeping for automatic steering:
