● 动力线、控制线以及PLC的电源线和I/O线应分别配线,隔离变压器与PLC和I/O之间应采用双胶线连接。将PLC的IO线和大功率线分开走线,如必须在同一线槽内,分开捆扎交流线、直流线,若条件允许,分槽走线好,这不仅能使其有尽可能大的空间距离,并能将降到低限度。 ● PLC应远离强源如电焊机、大功率硅整流装置和大型动力设备,不能与高压电器安装在同一个开关柜内。在柜内PLC应远离动力线(二者之间距离应大于200mm)。与PLC装在同一个柜子内的电感性负载,如功率较大的继电器、器的线圈,应并联RC消弧电路。 ● PLC的输入与输出好分开走线,开关量与模拟量也要分开敷设。模拟量的传送应采用屏蔽线,屏蔽层应一端或两端接地,接地电阻应小于屏蔽层电阻的1/10. ● 交流输出线和直流输出线不要用同一根电缆,输出线应尽量远离高压线和动力线,避免并行。
