8 DIGITAL INPUTS · 8 TRANSISTOR OUTPUTS · 24 VDC
Siemens 6ES7223-1BH32-0XB0 SIMATIC S7-1200 SM 1223 Digital I/O Module
An eight-input, eight-output SM 1223 signal module with 0.5 A transistor outputs and selectable input filtering.
Overview
6ES7223-1BH32-0XB0 combines eight 24 VDC digital inputs with eight 24 VDC transistor outputs in one S7-1200 signal module. Its inputs support sink/source field arrangements and its sourcing outputs are rated at 0.5 A per channel.
The input filter is parameterizable from 0.2 to 12.8 ms. Output short-circuit protection is not internal, so the installed project, load-current schedule and external protective devices define the service boundary.
Specifications
Features
Balanced local I/O
Pairs eight sensed states with eight fast DC commands in one module position.
Selectable input response
The project can tune standard-input filtering for the connected field-device behavior.
Fast transistor switching
Microsecond-scale output delays suit DC machine signals that do not need relay isolation.
Channel status diagnostics
Input and output status LEDs support commissioning checks against the PLC process image.

FAQ
How does 6ES7223-1BH32-0XB0 differ from 6ES7223-1PH32-0XB0?
6ES7223-1BH32-0XB0 uses 0.5 A transistor outputs; the 1PH32 variant uses 2 A relay contacts. Their field-voltage and switching behavior are not interchangeable.
Which project settings should be retained for 6ES7223-1BH32-0XB0?
Keep the hardware catalog selection, input filter times, channel addresses, startup values and any diagnostic handling.
Can 6ES7223-1BH32-0XB0 outputs be treated as short-circuit protected?
No. Siemens specifies that short-circuit protection must be provided externally for these outputs.
What wiring evidence is useful for an 6ES7223-1BH32-0XB0 spare?
Provide the terminal map, input polarity, output common arrangement, load currents, field-supply protection and complete label photograph.
How should 6ES7223-1BH32-0XB0 be tested after installation?
Exercise the eight inputs and eight outputs individually, verify address mapping and confirm the field devices reach their safe expected states.
