Description
Product Overview
The MOOG G122-824-002 P-I Servo Amplifier is an industrial control module designed to regulate electrohydraulic servo valves and proportional actuators in closed-loop control applications. It processes command and feedback signals using proportional (P), integral (I), or combined P-I control to produce a selectable voltage or current output.
The module accepts configurable analog command and feedback signals, allowing it to be integrated into hydraulic positioning, motion control, and industrial process-control systems. Adjustable gain, bias, feedback conditioning, and optional dither help engineers tune the amplifier for the requirements of the connected actuator and control loop.
Housed in a compact DIN-rail enclosure, the G122-824-002 is suitable for industrial machinery maintenance, hydraulic control systems, and replacement of existing servo amplifier installations. Before installation, verify the original wiring, internal switch settings, output configuration, and actuator requirements.

Frequently Asked Questions
Q1: What is the MOOG G122-824-002 used for?
A: It regulates servo valve or proportional actuator commands in industrial closed-loop control systems, particularly hydraulic positioning and motion-control applications.
Q2: What does P-I control mean?
A: Proportional control responds to the present error, while integral control responds to accumulated error over time. The amplifier can be configured for proportional, integral, or combined P-I operation.
Q3: What power supply does it require?
A: The specified supply is 24 V DC nominal, with an operating range of 22–28 V DC.
Q4: Which input signals does it support?
A: Depending on the selected configuration, the module supports 4–20 mA and voltage signals, including ±10 V inputs. Confirm the switch settings and wiring before use.
Q5: What output signals are available?
A: The output can be configured for ±10 V or selectable current levels from ±5 mA through ±50 mA. The correct setting depends on the connected valve or actuator.
Q6: What is the purpose of the dither function?
A: Dither introduces a small periodic signal to help reduce friction-related sticking in compatible servo valves. The G122-824-002 specifies a fixed 200 Hz dither frequency with selectable operation.
Q7: Can it replace the G122-824-001?
A: Supplier documentation identifies the G122-824-002 as a functional replacement for the -001 version, with additional input options, an output step button, and improved thermal performance. Verify wiring and application requirements before substitution.
Q8: What should I check before installation?
A: Confirm the model, supply voltage, input and feedback types, output selection, internal switch settings, terminal wiring, and actuator specifications. Installation and commissioning should be performed by a qualified controls technician.
