Siemens 6ES7288-2DT16-0AA0 SIMATIC S7-200 SMART SM DT16 Digital I/O Module
Eight 24 V DC inputs and eight 0.75 A transistor outputs in one SMART expansion module.
Product Overview
Siemens 6ES7288-2DT16-0AA0 is a SIMATIC S7-200 SMART SM DT16 Digital I/O Module identified by the complete submitted catalog string. The suffix and revision characters remain part of the supply identity.
Selection of 6ES7288-2DT16-0AA0 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
The mixed module combines eight digital input points and eight transistor output points.
Input circuits accept the documented 24 V DC sink/source field arrangement.
The transistor output section is separate from relay-output SM DR modules and must be matched to DC loads.
The complete 2DT16 ordering number prevents confusion with DT08, DT32 and DR16 variants.
Applications
- Compact machine panels that need equal numbers of 24 V DC inputs and transistor outputs.
- S7-200 SMART expansion where fast solid-state output switching is required.
- Like-for-like service of the exact SM DT16 position in an approved project.
Service Control
- Archive the STEP 7-Micro/WIN SMART project and record the expansion position and point map.
- Identify input commons, the two documented output supply groups and every connected load.
- Confirm load current, inrush and suppression before reconnecting the transistor outputs.
- Test the eight inputs and eight outputs individually, then prove the complete machine sequence.
FAQ
Can 6ES7288-2DT16-0AA0 replace the relay-output DR16 module?
Not without redesign. 6ES7288-2DT16-0AA0 uses 24 V DC transistor outputs, while the DR16 uses relay contacts.
How are the outputs on 6ES7288-2DT16-0AA0 supplied?
The Siemens wiring diagram separates the eight transistor outputs into documented supply/common groups; reproduce the installed 3L+/3M and 4L+/4M wiring.
What should be checked for inductive loads on 6ES7288-2DT16-0AA0?
Record steady and inrush current, switching frequency and the approved suppression for each coil before transfer.
Does 6ES7288-2DT16-0AA0 provide sixteen outputs?
No. DT16 refers to sixteen total mixed points: eight digital inputs and eight transistor outputs.
Which records should be retained after commissioning 6ES7288-2DT16-0AA0?
Keep the project version, module label, point map, supply measurements and individual input/output acceptance results.
