Compact CPUs Siemens

Область применения

Two compact CPUs with differing performance ranges are available for SIMATIC S7-1500:

CPU 1511C-1 PN:
with integrated I/Os and technological functions for applications with medium requirements on the program scope and processing speed, for distributed setup via PROFINET IO.
CPU 1512C-1 PN:
with integrated I/Os and technological functions for applications with medium requirements on the program scope and processing speed, for distributed setup via PROFINET IO.

Two compact CPUs with different performance levels and with integrated technological functions and integrated I/Os:
- CPU 1511C-1 PN
- CPU 1512C-1 PN
