The MODULbus interface is the playground to adapt the SCS and SCS 3 base units to the numerous electrical devices in the automation world. Whether a special counter is needed or a serial interface, a high resolution analogue input or a PT100 interface, a MODULbus module does all the interfacing not built already in the base unit. IO modules can be plugged in SCS or SCS 3 base units or MODULbus extension units.
