现在市场有那么多品牌的隔离器,价格参差不齐,该怎么选择呢?隔离器位于二个系统通道之间,所以选择隔离器首先要确定输入输出功能,同时要使隔离器输入输出模式(电压型、电流型、环路供电型等)适应前后端通道接口模式。此外尚有精度﹑功耗﹑噪音﹑绝缘强度﹑总线通讯功能等许多重要参数涉及产品性能,例如:噪音与精度有关、功耗热量与可靠性有关,这些需要使用者慎选。总之,适用、可靠、产品性价比是选择隔离器的主要原则。随着科学技术的发展,PLC在工业控制中的应用越来越广泛。PLC控制系统的可靠性直接影响到工业企业的安全生产和经济运行,系统的抗干扰能力是关系到整个系统可靠运行的关键。自动化系统中所使用的各种类型PLC,有的是集中安装在控制室,有的是安装在生产现场和各电机设备上,它们大多处在强电电路和强电设备所形成的恶劣电磁环境中。要提高PLC控制系统可靠性,设计人员只有预先了解各种干扰才能有效保证系统可靠运行。
