Siemens 6ES7222-1BF32-0XB0 SM 1222 8-Point Transistor Output Module
An eight-channel S7-1200 transistor-output module for documented 24 V DC load circuits.
Key Information
6ES7222-1BF32-0XB0 is the SIMATIC S7-1200 SM 1222 module with eight 24 V DC transistor outputs rated at 0.5 A per channel.
The solid-state output execution is electrically and operationally different from the eight-relay 1HF32 module. Load voltage, inrush current, suppression and output grouping must be reviewed against the actual machine circuit.
Siemens publishes a 0.155 kg net weight and a 9.00 × 10.90 × 5.70 cm package for this exact MLFB.
Functions
Solid-state load switching
Commands eight 24 V DC field loads through transistor output stages.
Fast discrete control
Supports switching duties suited to transistor outputs rather than mechanical relay contacts.
Point-level output mapping
Maintains a defined relationship between PLC tags, terminals and connected actuators.
Protected engineering boundary
Keeps current, grouping and external suppression within the documented load design.

FAQ
Is 6ES7222-1BF32-0XB0 the relay version of SM 1222?
No. It provides eight 24 V DC transistor outputs rated at 0.5 A; the 1HF32 article uses relays.
What load evidence should accompany a 6ES7222-1BF32-0XB0 order?
Send the output schedule, load voltage, steady and inrush currents, suppression method, slot and CPU identity.
Can 6ES7222-1BF32-0XB0 switch any 24 V DC actuator below 0.5 A?
The complete duty still needs review for inrush, inductance, switching frequency, grouping and external protection.
What must be isolated before replacing 6ES7222-1BF32-0XB0?
Follow the approved procedure for controller power, load supply and stored energy in every connected actuator circuit.
What confirms 6ES7222-1BF32-0XB0 is ready for production?
Verify each command, off-state, interlock, diagnostic indication and required safe response under supervised conditions.
