Switches eight independent field loads through relay dry contacts.
01
Product Overview
6ES7288-2DR08-0AA0 is the SIMATIC S7-200 SMART SM DR08 digital output module.
It provides eight isolated relay dry-contact outputs rated up to 2 A and requires a 24 V DC module supply.
Each output has a status LED for commissioning and maintenance.
02
Performance
Provides channel-to-channel isolation with a published 1500 V AC, one-minute isolation test.
Draws approximately 80 mA from the 24 V DC supply.
Uses approximately 90 mA from the 5 V DC backplane bus.

About IndustryParts
https://www.industryparts.com/Relay duty is reviewed point by point
IndustryParts keeps the 6ES7288-2DR08-0AA0 identity tied to the eight-load schedule and electrical protection record.
Dry contacts confirmed
Inrush duty reviewed
Eight outputs proved
04
System Integration
Document load voltage, steady current, inrush current and suppression for all eight outputs.
Isolate field power and the module supply before changing wiring.
Use separate protection appropriate to the connected load and conductor.
After configuration, prove every output under controlled conditions and confirm de-energized behavior.
05
Applications
Solenoid, contactor or indicator circuits within the relay ratings.
Mixed-voltage output groups that require isolated dry contacts.
Small machine panels needing eight additional relay outputs.
Replacement of an identical DR08 module with the original hardware configuration retained.

FAQ
Q01What load information should accompany a 6ES7288-2DR08-0AA0 request?
Provide voltage type, steady and inrush current, switching frequency, suppression and the protective device for each output.
Q02Are 6ES7288-2DR08-0AA0 outputs transistor outputs?
No. DR08 provides relay dry contacts; do not apply transistor-output wiring assumptions.
Q03Why should inductive loads be reviewed before installing 6ES7288-2DR08-0AA0?
Coils can produce high inrush and switching transients that require approved suppression and contact-duty checks.
Q04What should be tested after replacing 6ES7288-2DR08-0AA0?
Prove each commanded output, its load response, the OFF state, status indication and the relevant interlocks.
Q05Can 6ES7288-2DR08-0AA0 be selected from the eight-point count alone?
No. Output technology, contact rating, supply, isolation, hardware configuration and field wiring must match.
