Simrad AP26 and AP27 Autopilots
3.10Drive unit installation
The relations between drive units, drive unit voltage, autopilot computer, drive performance and interface to the steering gear are shown in the tables below.
Refer to the connecting diagram for the different drive units on page 60 onwards.
Installation instruction for the drive units are found in the manual for the individual units.
The maximum drive current capability of the AC10, AC20 and AC40 autopilot computers are different. Use the table below as reference and observe the notes on next page.

Notes !
1.The autopilot system detects whether a reversible motor or a solenoid is connected and outputs the correct drive signal automatically.
2.The drive output of AC10 is sufficient for any type of 12 and 24V solenoids normally found on a recreational boat.
