Product Summary
Siemens 6ES7223-1BH32-0XB0 is a SIMATIC S7-1200 SM 1223 mixed digital I/O module combining eight 24 V DC sink/source inputs with eight 0.5 A transistor outputs. It supports compact expansion where a machine requires both field-state acquisition and output switching in one module position. The unit is suited to planned I/O expansion, maintenance replacement and control-panel refurbishment. Before ordering, compare the complete suffix, CPU and STEP 7 project, input sensor wiring, output load current, protective devices, connector arrangement, mounting space and original product label.
INPUT BANK
8 DI / 24 V DC
Sink/source digital inputs for acquiring verified field states. Input filtering is parameterizable in the engineering project.
OUTPUT BANK
8 DQ / 0.5 A
Transistor outputs for switching compatible 24 V DC loads after current, wiring and protection checks.

Installation Decision Path
01
Match
Confirm the complete number, suffix and SM 1223 configuration.
02
Map
Compare the eight input and eight output addresses in the STEP 7 project.
03
Load
Check sensor type, 24 V DC wiring, output current and protective devices.
04
Fit
Verify connector, panel clearance, mounting orientation and station order.
05
Commission
Test channels under controlled conditions using approved procedures.
Applications
- Compact S7-1200 machine I/O expansion.
- Maintenance replacement of the same SM 1223 configuration.
- Panel refurbishment requiring both input acquisition and output switching.
- Verified 24 V DC sensor and actuator control circuits.
Compatibility Gate
Confirm the full suffix, CPU, station length, voltage and interface, hardware revision, firmware or software version, installation dimensions, field device type and original label photographs.
Revision notice: Please contact us to confirm the exact revision, firmware version, condition and availability before ordering.
Model-Specific FAQ
Is 6ES7223-1BH32-0XB0 currently available?
Availability is checked against the requested quantity and NEW condition. Send the complete part number for written confirmation.
What makes 6ES7223-1BH32-0XB0 different from an input-only module?
This SM 1223 combines eight digital inputs and eight transistor digital outputs in one module rather than providing only one signal direction.
How should compatibility be checked?
Verify the CPU, STEP 7 hardware catalog entry, station layout, 24 V DC input wiring, output loads, connector and full suffix.
Are the output loads protected internally?
Protection requirements must be checked against Siemens documentation and the actual load circuit. Confirm external protective devices before installation.
Can product and label photographs be supplied?
Photographs can be requested during quotation review so the complete number, labeling and physical configuration can be compared.
What warranty applies?
The requested supply condition includes 1 year warranty subject to the written quotation and return authorization terms.
