plc io module is divided into several modules by function

plc IO module is divided into several modules according to function, such as CPU modules, input modules, output modules, power modules, and so on. The module features a single mainframe digital output module is more some kind of modules and therefore relatively more. This can also be said to be the trend. At present, some medium-sized plc digital input output io module machine, the module features also tend to single species also increases Township. If the same OMRON Corporation C20 series PLC, H machine CPU unit to contain the power, and put the power ceded Ha machine, a separate power supply module.
