Siemens 6ES7222-1BD30-0XB0 SIMATIC S7-1200 SB 1222 4DQ 24V DC 200kHz Signal Board PLC I/O Module

The Siemens 6ES7222-1BD30-0XB0 SB 1222 is a signal board for the SIMATIC S7-1200 that adds 4 MOSFET digital outputs rated 24 V DC, switching up to 200 kHz for pulse-train motion control. Output current is 0.1 A per channel, and the board mounts directly on the CPU faceplate without consuming a backplane slot.

Selection Notes

200 kHz switching frequency makes this board suitable for pulse-train (PTO) step/direction outputs to small stepper or servo drives, where the standard 100 Hz transistor outputs on a full signal module fall well short. Because it plugs into the CPU's signal-board slot rather than the backplane bus, adding it does not use up one of the CPU's limited signal-module positions - reserve that slot for higher-current I/O instead. The 0.1 A output rating means it drives drive-input opto-couplers directly but not solenoids or relay coils without an interposing driver.

Applications

High-speed pulse output for stepper/servo drive step-and-direction control, and general low-current 24 V DC digital output expansion on space-constrained SIMATIC S7-1200 CPUs.
