Moog IN122-829A011 Servo Amplifier

Product Description

Moog IN122-829A011 (replaces legacy G122-829A001) is a general-purpose PI servo amplifier (PI SERVOAMP), DIN rail mounted analog control module. It is designed for closed-loop driving between PLC command signals and Moog electro-hydraulic servo / proportional valves. It supports Proportional(P), Integral(I), combined PI control modes. Internal DIP switches and front panel potentiometers allow custom configuration of gain, zero, scale and bias. It performs PI calculation of setpoint and feedback signals and outputs drive current directly to servo valves. It enables simple integration into PLC control systems and retrofit of old mechanical feedback (MFB) servo valve systems without hydraulic modification. Widely used in electro-hydraulic closed-loop position / force / pressure control.
