Digital Input Module - SM1221 16XDI - (6ES7221-1BH32-0XB0) for PLC S7-1200

Siemens SIMATIC S7-1200 PLCdigital input module, (W x H x D) 45 x 100 x 75 mm, 16 digital inputs, electrical connection type screw terminal connection.

At DamenCNC we often use these modules when we need to expand to extra input on the S7-1200 CPU.

This expansion card is placed to the right of the main CPU on the DIN Rail. Its a relativly compact unit that takes up 45mm of DIN Rail width.
