相应的功能要求 一般小型(低档)PLC具有逻辑运算、定时、计数等功能, 对于只需要开关量控制的设备都可满足。 对于以开关量控制为主,带少量模拟量控制的系统,可选用能带A/D和D/A转换单元,具有加减算术运算、数据传送功能的增强型低档PLC。对于控制较复杂,要求实现PID运算 、 闭环控制、通信联网等功能,可视控制规模大小及复杂程度,选用中档或高档PLC。 但是中、高档PLC价格较贵,一般用于大规模过程控制和集散控制系统等场合。 响应速度要求 PLC是为工业自动化设计的通用控制器,不同档次PLC的响应速度一般都能满足其应用范围内的需要。如果要跨范围使用PLC,或者某些功能或信号有特殊的速度要求时,则应该慎重考虑PLC的响应速度,可选用具有高速I/O处理功能的PLC,或选用具有快速响应模块和中断输入模块的PLC等。 CUTLER HAMMER D120-PM32 USPP D120PM32 CUTLER HAMMER D120PM33 300 SEC TIMER MODULE CUTLER HAMMER D120PM33 300 SEC TIMER MODULE CUTLER HAMMER D120PM33 TIMER Board CUTLER HAMMER D120PM33 TIMER Board CUTLER HAMMER D120PM33 TIMER GOOD TAKEOUT CUTLER HAMMER D120PM33 TIMER GOOD TAKEOUT Cutler Hammer D120PM33 Timer Module 300 Seconds !
