S08AO2

SeriesAnalog Module
AI/AO points8AO
COM PortBuilt-in 1*RS485
Remote I/O moduleSupported
8 channels analog output, A/D hardware conversion accuracy: 12 bits; Support 6 types of signals:[4,20]mA、[0,20]mA、[1,5]V、[0,5]V、[0,10]V、[-10,10]V; It can be used as the extended module for any types of PLC host; With the RS485 communication port, it can also be used as remote IO; When a extended module hanging at the back of the host though the parallel bus, it can be powered by the inner 24VDC on the host; It must be powered by external 220VAC when capacity of the inner 24VDC power supply is insufficient; When the module was used as remote I/O through serial bus, it must be powered by external 220VAC supply.
