描述
The G123-825 Buffer Amplifier is intended to interface between the output of
standard signal sources, such as a PLC or servo amplifier, and a Moog servo\
proportional valve. It accepts three types of signal input and can output most
of the Moog servo\proportional valve signals. It has a single pole active filter
to remove noise from the input signal.
PLC ±10 V and 4-20 mA inputs:
The G123-825 interfaces between standard PLC analog output signals of ±10 V
and 4-20 mA on the input side and the Moog valve on the output side. This solves
the compatibility problem between these signals and the valve requirement.
Mechanical feedback (mfb) valve input:
The G123-825 interfaces between the current output of a servo amplifier, on one
side, and a Moog valve on the other. This enables old mfb valves to be replaced by
modern electrical feedback (efb) valves, without changing the servo amplifier.
The buffer amplifier takes the existing servo amplifier output and converts it
to an efb compatible signal.
Input filter:
The G123-825 has a filter to remove noise from the input signal. The filter time
constant is switch selectable. The switch selections sum, so a large variety of time
constants is available.
G123-825缓冲放大器是用于接口之间的输出
标准信号源，如PLC或伺服放大器和Moog伺服\
比例阀。它可接受三种信号输入，且输出量最大
的穆格伺服比例阀信号。它有一个单极有源滤波器
从输入信号中去除噪声。
PLC±10 V和4-20 mA输入:
标准PLC模拟输出信号±10 V之间的G123-825接口
输入端为4-20 mA，输出端为穆格阀。这解决了
这些信号与阀门要求之间的兼容性问题。
机械反馈(mfb)阀输入:
将G123-825接口之间的电流输出一个伺服放大器，上一个
另一边是穆格阀。这使得旧的mfb阀门可以用
现代电反馈(efb)阀，不改变伺服放大器。
缓冲放大器采用现有的伺服放大器输出并将其转换
到efb兼容的信号。
输入滤波器:
G123-825有一个滤波器来去除输入信号中的噪声。过滤时间
常量是开关可选择的。开关的选择总和，所以时间变化很大
常量是可用的。
