电源模块的选择很简单，只需考虑输出电流。电源模块的额定输出电流必须大于CPU模块、I/O模块、模块等消耗电流的和，并留有一定的裕量。在选择电源模块时一般应考虑以下几点：
(1)电源模块的输入电压。电源模块可以包括各种各样的输入电压，有220V交流、110V交流和24V直流等。在实际应用中要根据具体情况选择，确定了输入电压后，也就确定了系统供电电源的输出电压。
(2)电源模块的输出功率。在选择电源模块时，其额定输出功率必须大于CPU模块、所有I/O模块等的消耗功率之和，并且要留有30%左右的裕量。当同一电源模块既要为主机单元又要为扩展单元供电时，从主机单元到*远一个扩展单元的线路压降必须小于。
(3)扩展单元中的电源模块。在有的系统中，由于扩展单元中安装有智能模块及一些特殊模块，就要求在扩展单元中安装相应的电源模块。这时相应的电源模块输出功率可按各自的供电范围计算。
(4)电源模块接线。选定了电源模块后，还要确定电源模块的接线端子和连接方式，以便正确地进行系统供电的设计。一般的电源模块的输入电压是通过接线端子与供电电源相连的，而输出信号通过总线插座与可编程控制器CPU的总线相连。
(5)系统的接地。电源模块接地线选择不小于10mm2的铜导线。与交流稳压器、UPS不间断电源、隔离变压器等及系统的接地之连线尽可能短;系统的地线也要和机壳相连。
(6)使用环境条件。在选择PLC时，要考虑使用现场的环境条件是否符合它的规定。一般要考虑的有：环境温度、相对湿度、电源允许波动范围和抗干扰等指标。
