Siemens 6ES7288-2DR16-0AA0 SIMATIC S7-200 SMART SM DR16 Digital I/O Module
Eight 24 V DC inputs and eight 2 A relay outputs for mixed-voltage load interfacing.
Module Profile
Siemens 6ES7288-2DR16-0AA0 is a SIMATIC S7-200 SMART SM DR16 Digital I/O Module identified by the complete submitted catalog string. The suffix and revision characters remain part of the supply identity.
Selection of 6ES7288-2DR16-0AA0 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 eight 24 V DC inputs with eight electromechanical relay outputs.
Relay contacts support approved load circuits that cannot be connected directly to a sourcing transistor output.
The DR16 wiring diagram defines input commons and the relay field-feed arrangement.
The full ordering number keeps the relay module distinct from DT16 and the higher-density DR32.
Integration Checks
- Archive the project and record all input commons, relay feeds, load voltages and point assignments.
- Inspect contact loads for steady current, inrush and approved suppression.
- Keep AC and DC circuit separation and conductor routing consistent with the panel design.
- Test all inputs, relay contacts, feedback signals and machine interlocks after installation.
Use Cases
- S7-200 SMART panels with mixed input monitoring and relay-switched field loads.
- Applications requiring contact isolation between the controller logic and approved load circuits.
- Like-for-like replacement of a documented SM DR16 expansion position.
FAQ
Q01Can 6ES7288-2DR16-0AA0 be replaced by 6ES7288-2DT16-0AA0?+
Not directly. DR16 uses relay contacts, while DT16 uses sourcing transistor outputs with different load and supply requirements.
Q02What should be recorded for each 6ES7288-2DR16-0AA0 relay output?+
Record load voltage, steady and inrush current, switching frequency, suppression and the terminal/feed arrangement.
Q03Does DR16 mean sixteen relay outputs on 6ES7288-2DR16-0AA0?+
No. It identifies sixteen mixed points: eight digital inputs and eight relay outputs.
Q04What panel checks matter before installing 6ES7288-2DR16-0AA0?+
Verify conductor segregation, branch protection, terminal tightness and the documented relay supply feeds.
Q05How should 6ES7288-2DR16-0AA0 be accepted after replacement?+
Exercise every input and relay output under controlled conditions, verify feedback and prove the complete interlock sequence.
