About the Manufacturer

6ES7221-1BH32-0XB0 is from the Simatic S7 family of programmable controllers which was first debuted by Siemens in 1995. There are three ranges within this family - the S7-200, S7-300 and S7-400, which are all suitable for different types of applications and environments. So which range is the best for which applications? As a basic outline, S7-200 are the smallest of the three and are most suited to basic tasks, S7-300 are for the mid range tasks in industries such as packaging and automotive, and S7-400 is the most powerful of the bunch making it suited to the most demanding applications. With a modular design, all S7 PLCs enable you to add or remove modules based on what you need from the controller. At Northern Industrial, we have loads of Siemens kit on the shelf including modules from the S7 range and can provide technical advice if you require.
