The F-8028CV is a 16-bit, 8-channel analog output module that features programmable output range on
all channels. It provides digital to analog conveter controlled by the system module to convert the digital
data into output signals. Users can specify the start up and safety value through configuration software.
Moreover, this module has ±0.05% accuracy for highly accurate application. Besides, the F-8028CV
provides 3000V
DC
optical isolation between channels and backplane bus. If any high voltage or current
damages these channels, this module won’t affect other component in iDCS-8000 system.
