C7-635
Do you lack sufficient space in your machine for a control and operating panel? The solution:
SIMATIC® C7. The compact control system consists of a standard S7-300 controller and an operator
panel both accommodated in a space-saving housing. The I/Os are even on-board. This enables
complete machine controls to be installed in the smallest of spaces and reduces the expenditure
required for assembly, installation, wiring and engineering. SIMATIC C7 offers integrated
technological functions such as counting, controlling, positioning and frequency measurement.
And if you decide to purchase the innovated SIMATIC C7-635 unit, you will enjoy improved
communication, processing and technological functions.
