Moog IN122-829A011 P-I Servo Amplifier

Product Description
IN122-829A011 is a DIN rail mounted configurable P-I servo amplifier manufactured by Moog, designed to drive Moog proportional and servo hydraulic valves in closed-loop control systems. It is an upgraded version of G122-829A series amplifier. This unit accepts standard analog command and feedback signals, performs proportional and integral closed-loop calculation, and outputs drive current to servo valve coils. It supports flexible parameter configuration via internal DIP switches and potentiometers, with built-in signal conditioning and overcurrent protection. Compact DIN rail housing, widely used as original spare control unit for metal forming, test bench, turbine and industrial hydraulic motion control systems.

Key Functions

• Switch-selectable P, I or PI combined closed-loop control mode
• Dual signal input options: ±10V voltage or 4-20mA current command & feedback signal
• High-precision current output to directly drive hydraulic servo / proportional valve coils
• Front panel potentiometers for gain, offset and integral time manual adjustment
• Built-in over-current, short-circuit protection for servo valve coil protection
• DIN rail mounting design for easy installation inside industrial hydraulic control cabinet
• Multi-channel summing input for setpoint, feedback and external limit signal superposition
• Compatible with PLC analog output, connects standard controller to Moog hydraulic valves

Application Scenarios

• Industrial hydraulic closed-loop control, servo valve and proportional valve drive
• Material test bench, fatigue testing machine, metal press and injection molding equipment
• Power plant, oil & gas turbomachinery hydraulic actuator control system
• Automation hydraulic retrofit, servo amplifier spare replacement and maintenance
• Dynamic motion simulation platform and industrial precision position / force control
