描述
可编程控制器利用I/O扩展接口使I/O扩展单元与PLC的基本单元实现连接,当基本I/O单元的输入或输出点数不够使用时,可以用I/O扩展单元来扩充开关量I/O点数和增加模拟量的I/O端子。
3.外设接口
外设接口电路用于连接手持编程器或其他图形编程器、文本显示器,并能通过外设接口组成PLC的控制网络。PLC通过PC/PPI电缆或使用MPI卡通过RS-485接口与计算机连接,可以实现编程、监控、连网等功能。
4.电源
电源单元的作用是把外部电源(220V的交流电源)转换成内部工作电压。外部连接的电源,通过PLC内部配有的一个专用开关式稳压电源,将交流/直流供电电源转化为PLC内部电路需要的工作电源(直流5伏、正负12伏、24伏),并为外部输入元件(如接近开关)提供24V直流电源(仅供输入端点使用),而驱动PLC负载的电源由用户提供。
