mood G123-825-001 放大器

1范围

这些应用笔记是G123-825的应用指南缓冲放大器。他们会告诉您如何安装、连接和调整缓冲放大器。他们不会告诉你如何设计使用它的闭环系统。

2描述

G123-825缓冲放大器提供两种类型的接口和过滤器。

2.1 PLC 10V和4-20mA

它连接标准PLC模拟输出模块，- 边是穆格阀，另-边是。它简化了在闭环中使用PLC。缓冲放大器解决了的常见问题4-20mA或10V PLC输出与不

兼容阀门驱动要求。

2.2机械反馈阀

它连接伺服放大器的电流输出，一边是穆格阀， 另-边是。这使得旧的机械反馈(mfb)阀将被现代电反馈(efb)伺服和比例阀，不带改变伺服放大器。

缓冲放大器采用现有的伺服放大器输出并将其转换为efb兼容信号。

1 Scope

These application notes are the application guide of G123-825 Buffer amplifier. They will show you how to install, connect, and adjust the Buffer amplifier. They won't tell you how to design a closed-loop system that uses it.

2 Description

The G123-825 Buffer amplifier provides two types of interfaces and filters.

2.1 PLC 10V and 4-20mA

It is connected to a standard PLC analog output module, with one side being the Mug valve and the other side being. It simplifies the use of PLC in closed-loop systems. Common problems solved by Buffer amplifier 4-20mA or 10V PLC output and

Compatible with valve drive requirements.

2.2 Mechanical feedback valve

It is connected to the current output of the servo amplifier, with one side being the Mug valve and the other side being. This allows the old mechanical feedback (MFB) valve to be replaced by modern electric feedback (EFB) servo and proportional valves without changing the servo amplifier.

The Buffer amplifier uses the existing servo amplifier output and converts it to efb compatible signal.
