题列的X430应为Y430、Y480(超出八进制数)、T460应为C460,C450应为T450、M790(不是八进制数编号)。
- 60MT的PLC,它最多可以接多少个输入信号?接多少个负7、有一台F1载?它适用于控制交流与直接负载吗?-60MT的PLC最多可接收36个输入信号,接24个负载,这是晶体参考答案:F1管输出式PLC,所以只适用于直流负载。
系列PLC和FX3U系列PLC有哪几种内部继电器(器件)是相同的?后8、F1者比前者多了哪种内部继电器?各有什么功能用途?系列PLC和FX3U系列PLC有以下相同的内部继电器而且功能用途参考答案:F1也相同:输入继电器X用于接收来自外部输入设备开关信号的接口,输出继电器Y是PLC向外部负载传送信号的器件,辅助继电器M相似于继电接触控制中用的中间继电器,供中间转换环节用,中间继电器又分为普通型和停电保持型、普通型和特殊用途型,定时器T用于定(延)时控制,计数器C用于计数,状态继电器S用于步进控制也可作为普通中间继电器用,数据寄存器D用于保存数据数值。
