The Europa 3508/04 combines with an input/output extender to provide a powerful small control system 

for heat treatment furnaces by customization. There are two I/O expanders available, 10-bit and 20-bit 

digital I/O. This remote input/output, combined with a graphical wiring editor, can be used as part of 

the furnace strategy to connect to other control components as well as drives and sensors of the

 furnace and quenching systems.
