一、产品概述

二、产品特点

（一）高精度信号隔离

1. 全维度隔离防护：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），彻底阻断控制系统与外部设备的电气通路。这种隔离不仅能有效抵御工业现场的噪声干扰（如电机运转产生的电磁噪声、变频器辐射干扰）、电压尖峰（如设备启停产生的瞬时高压），还能防止外部电路故障（如传感器短路、执行器过载）扩散至 PiC 控制器及其他核心模块，降低故障影响范围，显著提升系统的抗干扰能力与运行安全性。
2. 线性传输无失真：采用高精度信号调理与放大电路，确保模拟信号在隔离传输过程中严格保持线性特性。例如，对于 4-20mA 电流信号，输入 4mA 时输出精准对应 4mA，输入 20mA 时输出同步跟随 20mA，非线性误差可控制在 0.1% 以内；对于 0-10V 电压信号，能有效补偿传输过程中的信号衰减，避免因线路损耗导致的精度偏差。这种线性传输能力对依赖高精度模拟信号的场景（如精密温度控制、微米级位移反馈）至关重要，直接保障控制系统的控制精度。

Introduction to Giddings&Lewis 502-03430-00 Analog Isolator Module

1、 Product Overview

The Giddings&Lewis 502-03430-00 analog isolator module is a key module in the PiC series control system that achieves "analog signal protection and fidelity". It can be regarded as a "signal purification barrier" between the control system and external sensors and actuators. Its core function focuses on the isolation and buffering of analog signals: on the one hand, it cuts off the direct electrical connection between the control system and external devices through electrical isolation technology, eliminates noise interference and voltage spikes in industrial environments, and prevents external faults from spreading to the core control system; On the other hand, analog signals (such as voltage/current signals corresponding to temperature, pressure, and displacement) are linearly transmitted and buffered to ensure that the signals are transmitted without distortion or attenuation, providing accurate operating data for the PiC controller and outputting stable control signals to the actuator.

In the scenarios of CNC machine tools, industrial automation, and process control, this module is the core component that ensures the stability of analog signal transmission, directly affecting the control accuracy and operational reliability of the system, and providing important support for the precise and safe operation of industrial equipment.

2、 Product Features

（1） High precision signal isolation

Full dimensional isolation protection: The module constructs a reliable electrical isolation barrier (usually using optoelectronic or electromagnetic isolation technology) between the input and output terminals, completely blocking the electrical path between the control system and external devices. This isolation not only effectively resists noise interference from industrial sites (such as electromagnetic noise generated by motor operation, frequency converter radiation interference), voltage spikes (such as instantaneous high voltage generated by equipment start stop), but also prevents external circuit faults (such as sensor short circuits, actuator overload) from spreading to PiC controllers and other core modules, reducing the scope of fault impact and significantly improving the system's anti-interference ability and operational safety.

Linear transmission without distortion: high-precision signal conditioning and amplification circuits are used to ensure that analog signals strictly maintain linear characteristics during isolated transmission. For example, for a 4-20mA current signal, when inputting 4mA, the output accurately corresponds to 4mA, and when inputting 20mA, the output synchronously follows 20mA. The nonlinear error can be controlled within 0.1%; For 0-10V voltage signals, it can effectively compensate for signal attenuation during transmission and avoid accuracy deviation caused by line losses. This linear transmission capability is crucial for scenarios that rely on high-precision analog signals, such as precision temperature control and micrometer level displacement feedback, directly ensuring the control accuracy of the control system.
