G123-825-001 buffer amplifier MOOG

It is connected to the current output of the servo amplifier with a moog valve on one side and a Moog valve on the other. This allows the old mechanical feedback (mfb) valves to be replaced by modern valves for electrical feedback (efb) servos and proportional valves without changing the servo amplifier. The buffer amplifier takes the existing servo amplifier output and converts it into an efb compatible signal.
The buffer amplifier provides a filter to remove the noise input signal.

3.1 The position of a horizontal DIN rail, an industrial steel housing mounted on the vertical rear surface, is intended for an increasing number of methods. The G123-825 derailment card should be facing forward and down, so the front panel and terminal identification are readable, so the internal electronics receive cooling airflow. An important consideration for module placement is electromagnetic interference (EMI) from other enclosures within the device. For example, VF and AC servo drives can produce high levels of electromagnetic interference. Always check the EMC before placing the G123-825, please check other equipment for compliance in the vicinity.
Vents on the upper and lower sides of the G123-825 housing provide cooling for internal electronics. These vents should be kept awake. It is important to ensure that the equipment below does not produce the hot exhaust that heats the G123-825.
