SPERRY MARINE 03956 884214-I RUDDER SERVO AMPLIFIER
Original price was: $1,099.00.$477.00Current price is: $477.00.
The Sperry Marine 03956 884214-I (often listed as 1884214-I or V1.1) is a Rudder Servo Amplifier PCB. It is a critical component of Sperry Marine’s steering systems, such as the ADG 3000 VT or NAVIPILOT series.
Its primary function is to act as the interface between the autopilot/bridge commands and the hydraulic or electric steering gear.
Technical Function
In a marine steering loop, this amplifier board performs the following tasks:
-
Signal Amplification: It takes low-voltage control signals from the autopilot or steering control unit and amplifies them into high-current signals capable of driving the rudder’s servo valves or motors.
-
Feedback Comparison: It compares the Rudder Order (where the pilot wants the ship to go) with the Rudder Repeatback (the actual position of the rudder from the sensor).
-
Error Correction: If there is a difference between the order and the position, the amplifier drives the steering gear until the “error signal” reaches zero.
