Main features

  • Fully AF and RF on site programmable without changing any hardware
  • Structural flexibility - easy integration of AF options (NF8, DZ8, TG8, etc.)
  • Modularity - easy on site modifications (expansion or reduction) of the device structure (changes to the number of channels and of the output power)
  • Accessibility of information - status of PLC equipment (alarms, operational parameters, etc.) may be accessed from local and remote PLC terminal
  • Programmability by means of either a personal computer (PC) or integrated MMI console
