The F-8028CH is a 16-bit, 8-channel analog output module. It provides digital to analog converter 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. In addition to current output, F-8028CH is also built-in HART master interface to remotely maintain devices via HART. Besides, the F-8028CH provides 3000 VDC 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.
