Servocontroller SG 2000–Servo controller for proportional directional control valves : NORIS Group GmbH

Aluminum housing with vibration resistance according to IEC 60068
Easy integration of up to 2 proportional directional control valves for variable-pitch propeller systems
Fully compatible with all Noris system components
Project planning, integration, and service for all automation components from a single source
Self-monitoring can be accessed via fault output
Color-coded status LEDs for a quick overview of functional status

The servo controller can be easily integrated into the valve control circuit. A standard signal of +/-10V from the automation system generates the opening control for proportional directional valves. A jitter signal can be used to prevent the so-called "sticking" of the valves. The status of the integrated self-monitoring system can be accessed via a fault output. Color-coded status LEDs also provide a quick overview of the device's operational status.
