Description
The NORIS SG 2000 is a marine servo controller designed for proportional directional valves used in propulsion and automation systems. It converts a standard ±10 VDC command signal from the automation system into controlled proportional-valve actuation. The SG 2000 can control up to two proportional valve solenoids and is particularly suited to variable-pitch propeller systems. It incorporates PWM current control, valve anti-sticking jitter, self-monitoring, fault indication and status LEDs for practical integration into marine control cabinets and propulsion-control systems.

The current NORIS product page specifies a configurable maximum output current of 2.6 A, while the earlier SG 2000 manual documents a 1.5 A maximum for the proportional solenoid outputs. This difference may reflect hardware/configuration or product-generation variations, so the exact rating should be checked against the unit’s revision before replacement.

- The SG 2000 has marine type-approval documentation for applicable marine automation installations.
🔌 Control & Interface
The SG 2000 receives the propulsion-control command as a ±10 VDC setting value. An enable signal permits the controller to activate the corresponding proportional output. Depending on command polarity, the appropriate proportional solenoid is driven, with the output current controlled through PWM. The controller also monitors the control loop and auxiliary supply, allowing faults such as low supply voltage, wiring interruption or control-loop problems to be reported.
❓ FAQ
Q1: What is the NORIS SG 2000?
