Siemens 6ES7222-1BH32-0XB0 SIMATIC S7-1200 SM 1222 16 DO 24V DC 0.5A

The Siemens 6ES7222-1BH32-0XB0 is the SM 1222 Digital Output Module for the SIMATIC S7-1200 controller range, providing 16 transistor sourcing outputs at 24 V DC and 0.5 A per channel. Each channel is individually isolated from the backplane bus at 500 V AC, enabling diagnostics and fault containment in DC switching applications.
