SIEMENS Logo S7-200 Series EM 221 PLC Controller 6ES7 221-1BH22-0XA8 for Equipment Use

The Micro PLC SIMATIC S7-200 is truly in a class of its own: it’s both compact and highly powerful – especially considering its real-time response – it’s fast, features great communication options and comes with easy-to-operate software and hard- ware.
But there’s more; the Micro PLC SIMATIC S7-200 has a compact modular design – for customized solutions which aren’t too large, but flexible enough to be expand- ed anytime in the future.
All this makes the SIMATIC S7-200 a great choice for open-loop control in the
lower performance range. Become one of the thousands of S7-200 customers that constantly benefit from Siemens PLC in- novation and lower cost of ownership.

SIMATIC S7-200 delivers consistently economical solutions. The entire system family features
powerful performance,
optimum modularity and
open communications.
In addition, the SIMATIC S7-200 program- ming tools make your job even easier: this Micro PLC is easy to program allow- ing fast and easy realization of applica- tions – and the add-on software libraries accelerate special function configuration even more.
This Micro PLC has been in successful use in millions of applications around the world – in both stand-alone and net- worked solutions.
