Siemens 6ES7288-2DR32-0AA0 SIMATIC S7-200 SMART SM DR32 Digital I/O Module
Sixteen 24 V DC inputs and sixteen 2 A relay outputs in a 32-point SMART expansion module.
Module Profile
Siemens 6ES7288-2DR32-0AA0 is a SIMATIC S7-200 SMART SM DR32 Digital I/O Module identified by the complete submitted catalog string. The suffix and revision characters remain part of the supply identity.
Selection of 6ES7288-2DR32-0AA0 should follow the installed label, rack or controller record, field wiring and the verified technical details below; a neighboring family number is not treated as interchangeable.
Published Data
System Role
The module combines sixteen digital inputs and sixteen relay outputs in one expansion position.
Relay contacts can interface approved AC or DC load circuits when wired within the published ratings.
The higher point density requires complete terminal and group documentation before replacement.
The DR32 identity must not be confused with the transistor-output DT32 module.
Integration Checks
- Archive the project and photograph every connector before removing the module.
- Record input commons, relay feed groups, load voltages, currents, inrush and suppression.
- Check conductor segregation and branch protection for every voltage domain.
- Commission the sixteen inputs and sixteen relay outputs in controlled groups, then prove the entire process sequence.
Use Cases
- High-density S7-200 SMART panels with mixed input monitoring and relay-switched loads.
- Applications needing contact isolation and multiple load-voltage domains under approved segregation.
- Like-for-like replacement where the complete 32-point assignment is controlled.
FAQ
Q01How is 6ES7288-2DR32-0AA0 different from 6ES7288-2DT32-0AA0?+
DR32 uses sixteen relay outputs; DT32 uses sixteen sourcing transistor outputs. Their supply, load and switching characteristics differ.
Q02Does 6ES7288-2DR32-0AA0 provide thirty-two relay outputs?+
No. It has sixteen digital inputs and sixteen relay outputs, for thirty-two mixed points.
Q03Which field records are essential for 6ES7288-2DR32-0AA0?+
Retain the full point map, input commons, relay feed groups, load voltages, currents, protection and connector photographs.
Q04Can different load voltages be moved between 6ES7288-2DR32-0AA0 relay groups freely?+
No. Preserve the approved group wiring, segregation, protection and terminal ratings from the panel design.
Q05What should the final 6ES7288-2DR32-0AA0 test include?+
Test every input, every relay contact and real load feedback, then verify alarms, interlocks and safe shutdown behavior.
