The external power supply is used to drive the PLC output device(load)and provide input signals,also known as the user power supply.The external power supply of the same PLC may have multiple specifications.The capacity and performance of the external power supply are determined by the output device and the input circuit of the PLC.Since the I/O circuits of the PLC all have the functions of filtering and isolation,the external power supply has little effect on the performance of the PLC.Therefore,the requirements for external power supply are not high.

外部电源是用来驱动PLC输出设备(负载)和提供输入信号的，又称用户电源，同一台PLC的外部电源可能有多规格。外部电源的容量与性能由输出设备和PLC的输入电路决定。由于PLC的I／O电路都具有滤波、隔离功能，所以外部电源对PLC性能影响不大。因此，对外部电源的要求不高。
