PLC机型的选择的四个方面要考虑的因素

1．PLC的类型
   PLC按结构分为整体型和模块型两类，按应用环境分为现场安装和控制室安装两类；按CPU字长分为1位、4位、8位、16位、32位、64位等。从应用角度出发，通常可按控制功能或输入输出点数选型。整体型PLC的I/O点数固定，因此用户选择的余地较小，用于小型控制系统；模块型PLC提供多种I/O卡件或插卡，因此用户可较合理地选择和配置控制系统的I/O点数，功能扩展方便灵活，一般用于大中型控制系统。

2．输入输出模块的选择

输入输出模块的选择应考虑与应用要求的统一。例如对输入模块，应考虑信号电平、信号传输距离、信号隔离、信号供电方式等应用要求。对输出模块，应考虑选用的输出模块类型，通常继电器输出模块具有价格低、使用电压范围广、寿命短、响应时间较长等特点；可控硅输出模块适用于开关频繁，电感性低功率因数负荷场合，但价格较贵，过载能力较差。输出模块还有直流输出、交流输出和模拟量输出等，与应用要求应一致。可根据应用要求，合理选用智能型输入输出模块，以便提高控制水平和降低应用成本。考虑是否需要扩展机架或远程I/O机架等。

3.电源的选择

PLC的供电电源，除了引进设备时同时引进PLC应根据产品说明书要求设计和选用外，一般PLC的供电电源应设计选用220VAC电源，与国内电网电压一致。重要的应用场合，应采用不间断电源或稳压电源供电。如果PLC本身带有可使用电源时，应核对提供的电流是否满足应用要求，否则应设计外接供电电源。为防止外部高压电源因误操作而引入PLC，对输入和输出信号的隔离是必要的，有时也可采用简单的二极管或熔丝管隔离。

4.存储器的选择

由于计算机集成芯片技术的发展，存储器的价格已下降，因此，为保证应用项目的正常投运，一般要求PLC的存储器容量，按256个I/O点至少选8K存储器选择。需要复杂控制功能时，应选择容量更大，档次更高的存储器。
