Digital Servo
The Digital Servo Valve Controller takes input from a hall-effect style absolute SSI serial encoder, a 1~5 volt analog reference voltage input, and outputs a + 40ma signal to control a servo valve. This allows the unit to control a hydraulic servo valve so that the angle of a rotary actuator “tracks” the 1~5 volt reference signal.
