The Siemens 6ES7222-1BH32-0XB0 is a SIMATIC S7-1200 signal module, SM 1222 (SM 1222, DQ 16×24 V DC/0.5 A). Siemens describes it as: Digital output SM 1222, 16 DO, 24 V DC, 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.
Use it to drive contactor coils, solenoid valves, indicator lamps and relays when the CPU outputs run out. Relay outputs switch AC or DC loads on different voltages; transistor outputs are faster and wear-free for 24 V DC loads. Compatible CPUs include our CPU 1214C DC/DC/DC و CPU 1212C.
