MOOG P-I Servo Amplifiers G122-824

Description

The G122-824 P-I Servo Amplifier is used in closed-loop applications where a proportional and/or integral amplifier is required.

The amplifier's internal selector switch selects proportional, integral, or both. Many of the characteristics of the amplifier can be selected by the internal switches.

Thus, one amplifier can be used for many different applications. The configuration options offered are the result of many years of experience in the design and commissioning of closed-loop systems.

The servo amplifier uses analogue electronics. It accepts three input signals, two single-ended and one differential.

These signals are summed to produce an error signal, which is then scaled and integrated. The proportional and integral signals are switched together and output as current or voltage to drive the servo valve.

Trim potentiometers, LEDs and test points on the front panel allow for quick and easy setup and aid in troubleshooting.

The servo amplifier is housed in a compact DIN rail mounted enclosure and requires +24V power.
