Siemens 6ES7288-2DT32-0AA0 SIMATIC S7-200 SMART SM DT32 Digital I/O Module
Sixteen 24 V DC inputs and sixteen 0.75 A transistor outputs in a 32-point SMART expansion module.
Product Overview
Siemens 6ES7288-2DT32-0AA0 is a SIMATIC S7-200 SMART SM DT32 Digital I/O Module identified by the complete submitted catalog string. The suffix and revision characters remain part of the supply identity.
Selection of 6ES7288-2DT32-0AA0 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.
Technical Register
Operating Features
Thirty-two mixed points are divided evenly between digital inputs and transistor outputs.
The 24 V DC input circuits comply with the documented sink/source arrangement.
Fast solid-state output switching suits approved DC loads but does not provide relay-contact isolation.
The 2DT32 code must not be shortened to DT32 when ordering or documenting the installed module.
Applications
- S7-200 SMART machines requiring a dense mixed 16-input/16-output expansion block.
- DC solenoid, indicator and interface loads within the transistor-output ratings.
- Controlled replacement where the full 32-point map and supply grouping are available.
Service Control
- Save the project and export the complete 16-input/16-output address map.
- Record every field common, output supply group, load current and suppression device.
- Check 24 V DC supply quality and total load before installing the spare.
- Prove all thirty-two points, output-off behavior and machine interlocks before production.
FAQ
Does 6ES7288-2DT32-0AA0 provide thirty-two transistor outputs?
No. It has sixteen 24 V DC inputs and sixteen transistor outputs, for thirty-two mixed points.
Can 6ES7288-2DT32-0AA0 switch AC loads directly?
No. Its outputs are 24 V DC transistor outputs; use an approved interposing device when the application requires another load type.
What supply range applies to 6ES7288-2DT32-0AA0?
The published 24 V DC supply range is 20.4 to 28.8 V DC.
Why should output suppression be reviewed for 6ES7288-2DT32-0AA0?
Inductive-load energy and switching frequency affect transistor-output stress, so the installed suppression and inrush must be documented.
What acceptance record is appropriate for 6ES7288-2DT32-0AA0?
Record module identity, project checksum, supply voltage, all point tests, load feedback and the final machine safety/interlock check.
