Giddings & Lewis 502-03326-00 线性隔离器模块介绍

一、产品概述

二、产品特点

（一）电气隔离

1. 双向防护隔离：模块在输入与输出端之间构建可靠的电气隔离屏障（通常采用光电隔离或电磁隔离技术），彻底切断控制系统与外部设备的直接电气通路。这种隔离不仅能保护 PiC 系列控制器及其他核心模块免受外部干扰（如电机启停产生的电压尖峰、传感器线路噪声），还能防止控制系统内部故障（如短路）扩散至外部负载（如执行器、传感器），降低故障影响范围，提升整个系统的安全性与稳定性。
2. 抗干扰能力强化：通过隔离设计，有效抑制工业现场常见的噪声干扰、电压突变及短路风险。例如，在数控机床中，主轴电机运转产生的强电磁噪声易通过信号线路侵入控制器，模块可通过隔离屏障阻断噪声传递；当外部传感器线路发生短路时，隔离设计能避免短路电流流入控制器，防止控制器损坏。这种防护能力确保系统在复杂电气环境中仍能稳定运行，减少因干扰导致的控制误差或设备故障。

（二）线性信号传输

1. 全类型信号适配：具备出色的信号兼容性，可准确传递模拟量信号（如温度、压力传感器的 4-20mA 电流信号、0-10V 电压信号）与数字量信号（如开关通断信号、编码器脉冲信号）。在信号传递过程中，严格保持信号的线性特性 —— 例如，输入 4mA 模拟信号时输出精准对应 4mA，输入 20mA 时输出同步跟随 20mA，无非线性失真，确保控制系统接收的反馈信号与实际工况一致，下发的控制指令能精准传递至执行元件。
2. 信号保真无衰减：采用高精度信号放大与调理电路，避免信号在隔离传输过程中出现衰减或畸变。例如，在远距离信号传输场景（如自动化生产线中控制器与远端传感器的连接），普通线路易因电阻损耗导致信号衰减，模块可通过内部缓冲放大电路补偿信号损耗，确保信号强度与精度满足控制需求。这种特性对依赖高精度信号的场景（如精密温度控制、微米级位置反馈）至关重要，直接保障系统的控制精度。

Introduction to Giddings&Lewis 502-03326-00 Linear Isolator Module

1、 Product Overview

The Giddings&Lewis 502-03326-00 linear isolator module is a functional module in the PiC series control system that serves as both a "signal protection shield" and a "fidelity transmitter". Its core value lies in solving the interference and safety issues of signal transmission in industrial environments - by using electrical isolation technology to cut off the direct electrical connection between the control system and external loads and signal sources, preventing external interference signals from invading or spreading faults; At the same time, the linear transmission characteristics ensure that analog and digital signals have no distortion or attenuation during the isolation process, achieving precise transmission of control instructions and feedback data.

This module is widely used in CNC machine tools, automation equipment, and industrial control systems. It is a key component to ensure signal transmission stability and improve system anti-interference ability in complex industrial environments, providing important support for the safe and accurate operation of industrial equipment.

2、 Product Features

（1） Electrical isolation

Bidirectional protective isolation: The module constructs a reliable electrical isolation barrier between the input and output terminals (usually using optoelectronic isolation or electromagnetic isolation technology), completely cutting off the direct electrical path between the control system and external devices. This isolation not only protects PiC series controllers and other core modules from external interference (such as voltage spikes generated by motor start stop and sensor circuit noise), but also prevents internal faults (such as short circuits) of the control system from spreading to external loads (such as actuators and sensors), reducing the scope of fault impact and improving the safety and stability of the entire system.

Enhanced anti-interference capability: Through isolation design, it effectively suppresses common noise interference, voltage fluctuations, and short circuit risks in industrial sites. For example, in CNC machine tools, the strong electromagnetic noise generated by the spindle motor can easily enter the controller through signal lines, and the module can block the noise transmission through isolation barriers; When a short circuit occurs in the external sensor circuit, isolation design can prevent short-circuit current from flowing into the controller and prevent damage to the controller. This protective capability ensures stable operation of the system in complex electrical environments, reducing control errors or equipment failures caused by interference.

（2） Linear signal transmission

Full type signal adaptation: With excellent signal compatibility, it can accurately transmit analog signals (such as 4-20mA current signals from temperature and pressure sensors, 0-10V voltage signals) and digital signals (such as switch on/off signals, encoder pulse signals). In the process of signal transmission, the linear characteristics of the signal are strictly maintained - for example, when inputting a 4mA analog signal, the output accurately corresponds to 4mA, and when inputting 20mA, the output synchronously follows 20mA, without any non-linear distortion, to ensure that the feedback signal received by the control system is consistent with the actual working conditions, and the control instructions issued can be accurately transmitted to the executing components.
