In summary, the MOOG G122-829-001 is a versatile P-I servoamplifier designed for precise control of hydraulic servo valves in closed-loop systems, offering multiple configuration options and feedback capabilities.
The MOOG G122-829-001 is a Servoamplifier. It’s designed for use in closed-loop applications where proportional and/or integral control is needed for servo valves.
Core Functionality:
P, I, or P & I Control: Selectable via an internal switch, allowing for versatile control modes.
Multiple Inputs: Accepts three input signals:
Input 1: Scalable up to ±95V via a switch.
Input 2: 4-20mA (with a 240Ω load, can also accept 0 to +10V).
Input 3: ±10V input that directly corresponds to ±100% valve drive.
Differential Feedback Input: Switch-selectable for 4-20mA or ±10V signals.
Output Amplifier: Switch-selectable for voltage or current output (single-ended).
Step Push Button: Provides a -50% valve drive disturbance for testing.
Dither: Fixed frequency of 200 Hz to improve valve response.
Key Specifications:
Supply Voltage: +24V DC nominal (range 22 to 28V).
Current Consumption: Maximum 250mA (requires a 250mA T slow blow fuse).
Output to Valve: Pin 14, maximum 300mA.
“In Position” Output: ±10% of valve drive, maximum 20mA and 40V for PLC feedback.
Proportional Gain: Adjustable from 1 to 20.
Integral Gain: Adjustable from 1 to 45 per second.
Transducer Excitation: +10V DC @ 10mA maximum.
Operating Temperature: Not explicitly stated in the brief search results, refer to the datasheet.
Mounting: DIN rail.
Wiring: Accepts wire sizes from 0.2mm² to 2.5mm² (24AWG to 12AWG).
The G122-829-001 is a functional replacement for the G122-824-002 version, although it has a different pin-out and improved high gain performance.
