G122-824-002  P-I Servoamplifier

The G122-824 P-I Servoamplifier is used in closed loop applications where a proportional and/or integral amplifier is needed. Selector switches inside the amplifier enable proportional, integral or both to be selected. Many aspects of the amplifier’s characteristics can be selected with internal switches. This enables one amplifier to be used in many different applications. The configuration options provided are the result of many years of experience in designing and commissioning closed loop systems.
The Servoamplifier employs analog electronics. It accepts three input signals, two single ended and one differential.

This enables one amplifier to be used in many different applications. The configuration options provided are the result of many years of experience in designing and commissioning closed loop systems.
The Servoamplifier employs analog electronics. It accepts three input signals, two single ended and one differential.
These are summed to produce an error signal which is then amplified proportionally and also integrated. The proportional and integral signals are switched together and output as a current or voltage to drive a servovalve.
Front panel trim pots, LED indicators and test points allow fast and easy setup and aid in trouble shooting. The servoamplifier is housed in a compact DIN rail mounting enclosure and requires a +24V supply

G122-824-002  P-I Servoamplifier

The Moog range of DIN module power supplies has been recently released foruse in analog and digital systems operating from 24 volts DC. There are twosizes available with G128-808 for 650 mA and Gl28-809 for 2 Amps; but eachcan be operated to a higher output current subject to voltage, duty cyele andambient temperatures. Details regarding these higher operating limits can befound in the Application Notes for these products.
The smaller Gl28-808 is suited to control systems with low power controlvalves such as mechanical feedback [MFB]or electrical feedback 「EFB]valveswith low power pilots. For valves such as the Moog Direct Drive [DDV]models D633, D634, the G128-809 can be applied to provide power to both thecontrol system and valve electronics.
Features include:
Wide range of AC or DC input.
Regulated +24 VDC, low ripple output.Idle and short circuit protected.Isolation from input supplyG128-808 @ 3kv,G128-809 @ 4 kV
High efficiency, >80%.
High reliability, 500,000 MTBF.
Parallel connection for redundant operation.
CE marked.
