VACON® Functional extensions

VACON® Functional extensions are plug-in option boards that expand the digital and analog I/O, relay outputs, and feedback interfaces of VACON® NXS, NXP, NXL, 100 and 20 series drives. The range covers Safe Torque Off safety modules, encoder and resolver interfaces (TTL, HTL, Sin/Cos, EnDat, SSI, BiSS C), PT100 temperature measurement, and general-purpose I/O expanders. Each board fits a defined drive slot, letting integrators tailor a VACON® drive precisely to the control, safety and feedback needs of the application.
