SIMATIC S7-1200 controllers are the ideal choice when it comes to flexible and efficient execution of automation tasks in the low to medium power range. They are characterized by a comprehensive range of technological functions and integrated communication, as well as a particularly compact and space-saving design. The SIMATIC S7-1200 can be tailored to almost any industrial application thanks to wide expansion options. The integrated PROFINET interface ensures a perfect interplay of other elements of automation technology in the unified TIA Portal engineering environment. The modular concept of the control system facilitates its expansion, moreover, without changing its physical dimensions

Simatic S71200-modules

CPU - High speed I/O

On the SIMATIC S7-1200 you will find up to 6 high-speed inputs and 2 high-speed outputs. Three high-speed inputs, which are integrated on the base unit - CPU, can be used for frequencies up to 100 kHz. The high-speed outputs can be used for controlling stepper motors or for PWM pulse width modulation with a maximum frequency of 100 kHz. By inserting signal modules, we get high-speed inputs/outputs that allow us to work with frequencies up to 200 kHz!

CPU - Signal modules

One signal module can be inserted into all types of SIMATIC S7-1200 CPUs and thus expand the number of digital and analog inputs/outputs without increasing the space occupied in the cabinet. It serves as a supplement to the integrated I/O on the base unit. These are modules that can be inserted directly into the basic units of the S7-1200 series. Siemens currently offers analog, digital input and output signal modules, modules for connecting thermocouples and resistance sensors, RS485 communication module

Signal cards

Signal cards can be used to expand the number of digital and analog inputs/outputs on the base unit. Signal cards are connected from the right side of the CPU and their number depends on the type of CPU. The CPU 1211 allows no signal card to be connected, the CPU 1212 two and the CPU 1214 up to eight signal cards.
