The NCi-5 #A-5259-2000 provides an interface between a laser tool setting probe and a CNC machine controller. It is a direct replacement for the now obsolete NCi-4 and is 100% backward compatible. It also offers additional functionality. The NCi-5 interface is used with the NC1, NC3 and NC4 non-contact tool setting systems. It processes signals from the non-contact tool setter and converts them into a voltage-free solid state relay (SSR) output, for transmission to the CNC machine control.
