With the addition of a signal board, you can increase the number of digital or analog I/Os on the controller to custom-fit your needs without increasing the controller‘s footprint.
The SIMATIC S7-1200 system comes in three different models, CPU 1211C,CPU 1212C and CPU 1214C, that may each be expanded to exactly fit your machine requirements.
One signal board can be added inside the front of any CPU to easily expand the digital or analog I/Os without affecting the physical sizeof the controller.
Signal modules can be connected to the right side of the CPU to further expand the digital or analog I/O capacity. CPU 1212C accepts twoand CPU 1214C accepts eight signal modules.Have an Inquiry for Siemens about this article? Click Here >>
