The GRX-TVI provides 0-10V control and ballast switching capabilities in one enclosure. The GRX-TVI gives GRAFIK Eye 3000 series control units the ability to control any 0-10V ballasts powered by 100V-277V (ballast must provide 0-10V sourcing of current) and provides switching relays that can handle the in-rush current for a circuit of ballasts. The GRX-TVI gives a GRAFIK Eye 3000 series control unit the ability to both dim and switch electronic ballasts.
