The Siemens 6ES7221-1BF32-0XB0 is a SIMATIC S7-1200 SM 1221 digital input module with 8 inputs. Signal modules of the S7-1200 family mount to the right of the CPU and expand its onboard I/O over the integrated backplane bus connector; no separate rack or interconnect cabling is required.
The 24 V DC inputs are sink/source capable, so they work with both sourcing and sinking field devices such as sensors, pushbuttons, and limit switches.
