SIEMENS SIMATIC S7-1200 – 6ES7221-3BD30-0XB0
The SIMATIC S7-1200 controller is modular and compact, versatile, a secure investment, and is powerfully fit for a full range of applications. A scalable and flexible design, a communication interface that fulfills the highest standards of industrial communication and a full range of powerful integrated technology functions make this controller an integral part of a complete and comprehensive automation solution.
Highest efficiency in engineering SIMATIC S7-1200 is programmed via the new and fully integrated engineering-system SIMATIC STEP 7 Basic with SIMATIC WinCC Basic. SIMATIC STEP 7 Basic is designed to be intuitive easy to learn and easy to use. This provides you with highest efficiency in engineering.
Smart functionalities such as intuitive editors, drag and drop functionality as well as “IntelliSense“ tools simply let you engineer faster. This new software architecture comes from a stable source for future innovations – Siemens has many years of experience in software development and has thus made SIMATIC STEP 7 Basic highly future-oriented.
- Digital inputs as a supplement to the integral I/O of SIMATIC S7-1200 CPUs
- Can be plugged directly into the CPU
The SB 1221 digital input signal boards enable connection of the controller to digital process signals.
The Signal Boards are plugged straight into the holder on the front of the S7-1200-CPU.
Signal Boards are plugged direct into the SIMATIC S7-1200-CPU and linked electrically and mechanically with the CPU in this way.
- The installation dimensions of the CPU remain unchanged.
- On all Signal Boards, replacement is facilitated by removable terminals (“permanent wiring”).
The SB 1221 digital input/output signal board converts the level of the external digital signals from the process to the internal signal level of the S7-1200 Controller.
