The G122-829A 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, one single ended and two 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 DC supply.
