SeriesDigital Module
DI/DO points16DO, Transistor PNP output
COM PortBuilt-in 1*RS485
Remote I/O moduleSupported
The 16 DO(transistor outputs) can be used as the extension module for any types of PLC host;With the RS485 communication, it can also be used as remote IO; When a extension module hanging at the back of the host through the parallel bus, it can be powered by the inner 24VDC on the host; It must be powered by external 24VDC when capacity of the inner 24VDC supply is insufficient; When the module was used as remote I/O through serial bus, it must be powered by external 24VDC supply.
