The Siemens 6ES7221-1BH32-0XB0 is a SM 1221 Digital Input Signal Module that converts the level of the external digital signals from the process into the internal signal level of the S7-1200. The signals can be mixed as desired, and users can then adapt their controllers exactly to the relevant task. This signal module is supplied with 16 input channels.
