Innovative digital inputs
All the digital inputs present in the stepper motor drives of the xS10, DS30 and DS5x series are optoisolated.
Each optocoupler has an innovative current limiting circuit that allows to supply each input singularly, and independently one from the other, with voltage from 3Vdc to 28Vdc without having to add limiting external resistors.
The innovative solution adopted allows to easily interface to control systems with CMOS/TTL output, Line Driver or voltage levels of 0/12Vdc or 0/24Vdc.
Each input can then be individually configured to operate in NPN or PNP logic.
