Moog N122-824-002 P-I Servo Amplifier

Product Description

The Moog N122-824-002 is a proportional-integral (P-I) servo amplifier for closed-loop hydraulic servo valve control systems. It is the upgraded version of the earlier -001 variant, equipped with an additional 4-20mA input option for channel 2, output step test button and improved thermal design. It adopts DIN rail mounting, supports flexible gain mode selection via internal DIP switches, and delivers stable drive current to Moog servo valves. This legacy servo amplifier is supplied as new surplus or fully tested refurbished spare parts for test benches, simulators and hydraulic motion control retrofit projects.

Product Functions

• Proportional, integral or combined P-I control mode selectable via internal switches
• Accept multiple command signal types including 4-20mA, voltage and differential feedback signals
• Provide ± current or ± voltage output to drive hydraulic servo valves
• Built-in step test button for quick loop commissioning and valve performance verification
• Onboard overcurrent, overheating and short-circuit protection circuits
• Compact DIN rail installation for easy integration into hydraulic control cabinets

Application Scenarios

• Hydraulic vibration test benches, material fatigue and structural simulation systems
• Aerospace component test rigs and flight simulator hydraulic control units
• Industrial hydraulic press, bending machine and high-precision positioning platforms
• Automotive durability test equipment and servo hydraulic control systems
• Spare replacement and repair of existing Moog servo valve closed-loop control systems
