Giddings & Lewis 502-03898-50 直流输出板介绍

一、产品概述

二、产品特点

（一）多通道直流输出

1. 多路并行控制：模块设计有多个独立的直流输出通道（具体通道数根据型号配置，常见为 8 路、16 路等），支持同时对多路直流负载进行独立控制。例如，在自动化生产线中，可同时驱动 4 台输送带直流电机、2 台分拣气缸电磁阀、3 盏状态指示灯，无需分时处理，大幅提升了负载驱动效率，满足多设备同步协同的复杂控制需求，避免因通道不足导致的系统架构复杂化。
2. 通道隔离防干扰：各输出通道之间采用严格的电气隔离设计（如光电隔离、继电器隔离），彻底切断通道间的电气连接。这种设计能有效降低不同通道负载之间的信号干扰 —— 例如，避免大功率电磁阀动作时产生的电压波动影响指示灯的稳定显示；同时，可防止某一通道故障（如负载短路）扩散至其他通道，将故障影响范围控制在单通道内，显著提升系统的容错能力与运行可靠性。

（二）高可靠性与保护功能

1. 双重故障防护：内置过流保护与短路保护电路，为模块与负载提供双重安全保障。当外部直流负载出现过流（如电机堵转导致电流超出额定值）或线路发生短路时，保护机制会迅速触发 —— 通过切断故障通道的输出电源或限制电流输出，防止过大电流损坏模块内部功率元件及外部负载（如昂贵的电磁阀、精密继电器）。例如，当指示灯线路意外短路时，模块可在毫秒级时间内切断该通道输出，避免短路电流烧毁模块，待故障排除后，模块可自动恢复正常工作，无需人工维修。
2. 工业级耐用设计：采用工业级硬件选材与结构优化，核心元器件（如功率管、继电器）均经过严格的环境耐受性测试（如高温、低温、湿度循环测试）与机械应力测试（如振动、冲击测试），具备出色的抗老化、抗损耗能力。结构上采用加固外壳与防震支架，能承受数控机床运转、自动化设备搬运产生的振动（加速度可达 5g）与冲击（峰值加速度可达 50g），避免内部元件松动或线路接触不良，确保在复杂工业环境中长期稳定运行。

Introduction to Giddings&Lewis 502-03898-50 DC Output Board

1、 Product Overview

The Giddings&Lewis 502-03898-50 DC output board is a key interface module in the PiC series control system that connects "control commands" and "mechanical actions", and can be called the "power execution relay station" of the control system. Its core function is to accurately convert the logic signals (such as high and low level commands, switch control signals) issued by the PiC controller into electrical signals (such as DC voltage and current) that can drive DC loads through internal circuits, and ultimately drive DC actuators such as relays, solenoid valves, indicator lights, etc. to achieve precise control of industrial equipment mechanical actions by the control system.

In CNC machine tools and automation equipment, this module is an indispensable "instruction executor" - whether it is the clamping and loosening of CNC machine tool fixtures, the start and stop of automated production line conveyor belts, or the status switching of signal indicators, they all rely on their stable signal conversion and load driving capabilities, providing solid execution guarantees for the precision and automation of industrial production.

2、 Product Features

（1） Multi channel DC output

Multi channel parallel control: The module design has multiple independent DC output channels (the specific number of channels is configured according to the model, commonly 8, 16, etc.), supporting independent control of multiple DC loads simultaneously. For example, in an automated production line, 4 conveyor belt DC motors, 2 sorting cylinder solenoid valves, and 3 status indicator lights can be driven simultaneously without the need for time-sharing processing, greatly improving load driving efficiency and meeting the complex control requirements of multi device synchronization and collaboration, avoiding system architecture complexity caused by insufficient channels.

Channel isolation and anti-interference: Strict electrical isolation design (such as photoelectric isolation and relay isolation) is adopted between each output channel to completely cut off the electrical connection between channels. This design can effectively reduce signal interference between different channel loads - for example, to avoid voltage fluctuations caused by the operation of high-power solenoid valves that affect the stable display of indicator lights; At the same time, it can prevent a fault in one channel (such as a load short circuit) from spreading to other channels, control the impact range of the fault within a single channel, and significantly improve the system's fault tolerance and operational reliability.

（2） High reliability and protection function

Double fault protection: Built in overcurrent protection and short-circuit protection circuits provide dual safety protection for modules and loads. When an external DC load experiences overcurrent (such as motor stalling causing current to exceed the rated value) or a short circuit occurs in the circuit, the protection mechanism will quickly trigger - by cutting off the output power of the faulty channel or limiting the current output, it prevents excessive current from damaging the internal power components of the module and external loads (such as expensive solenoid valves and precision relays). For example, when the indicator light circuit accidentally short circuits, the module can cut off the output of the channel within milliseconds to avoid the short-circuit current burning out the module. After the fault is eliminated, the module can automatically resume normal operation without manual maintenance.
