Siemens 6ES7221-3BD30-0XB0 S7-1200 SB 1221 Digital Input Module

The Siemens 6ES7221-3BD30-0XB0 is a SB 1221 Digital Input/ Output Signal Module that converts the level of the external digital signals from the process to the internal signal level of the S7-1200. The 24V Signal Board is 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.
