The Siemens 6ES7223-1BH32-0XB0 is a SIMATIC S7-1200 signal module, SM 1223 (SM 1223, DI 8×24 V DC, DQ 8×24 V DC). Siemens describes it as: Digital I/O SM 1223, 8 DI/8 DO, 8 DI 24 V DC, Sink/Source, 8 DO, transistor 0.5 A.
It clips onto the right-hand side of an S7-1200 CPU on the same DIN rail and connects through the integrated bus connector, so no separate wiring is needed between CPU and module. Per the Siemens CPU data, a CPU 1212C takes up to 2 signal modules and CPU 1214C and 1215C up to 8.
It adds inputs and outputs in one module, which saves rail space on small machines. Compatible CPUs include our CPU 1214C DC/DC/DC و CPU 1212C.
