The PLC power supply is 50Hz,220V±10%alternating current.

FX series programmable controllers have DC 24V output terminals.This terminal can provide DC 24V power supply for input sensing(such as photoelectric switch or proximity switch).

If the power supply fails and the interruption time is less than 10ms,the PLC operation will not be affected.If the power supply is interrupted for more than 10ms or the power drop exceeds the allowable value,the PLC will stop working and all output points will be disconnected at the same time.When the power is restored,if the RUN input is turned on,the operation is performed automatically.

For the interference from the power line,the PLC itself has enough resistance.If the power supply interference is particularly serious,an isolation transformer with a ratio of 1:1 can be installed to reduce the interference between the equipment and the ground.

PLC供电电源为50Hz、220V±10%的交流电。

FX系列可编程控制器有直流24V输出接线端。该接线端可为输入传感（如光电开关或接近开关）提供直流24V电源。

如果电源发生故障，中断时间少于10ms，PLC工作不受影响。若电源中断超过10ms或电源下降超过允许值，则PLC停止工作，所有的输出点均同时断开。当电源恢复时，若RUN输入接通，则操作自动进行。

对于电源线来的干扰，PLC本身具有足够的抵制能力。如果电源干扰特别严重，可以安装一个变比为1:1的隔离变压器，以减少设备与地之间的干扰。
