The Siemens 6ES7288-2QR16-0AA0 is a SIMATIC S7-200 SMART SM QR16 Relay Output Module that provides sixteen relay-only outputs in a 45 mm expansion module.
- SM QR16
- 16 relay digital outputs
- 24 V DC nominal; 20.4 to 28.8 V DC permissible
- 45 x 100 x 81 mm
In an S7-200 SMART automation station, it converts sixteen controller output bits into isolated dry-contact relay switching for approved AC or DC field loads. It works with the verified CPU or expansion-bus configuration, terminal blocks, field power, sensors, and actuators defined for the exact article number. The module is used in banked solenoids, contactor groups, alarms, lamps, and multi-actuator machine sections.
Important Notice: Use the complete 6ES7288-2QR16-0AA0 code and verify the physical nameplate, current Siemens documentation, field wiring, project, and accessories before installation or replacement.

Machine and process panels
Supports banked solenoids, contactor groups, alarms, lamps, and multi-actuator machine sections
Read the exact Siemens S7-200 SMART documentation before use. Verify 6ES7288-2QR16-0AA0, SM QR16, power, I/O wiring, terminals, and project from the physical installation.
1
Identity: Match every character of 6ES7288-2QR16-0AA0 and the SM QR16 marking to the physical nameplate and project
2
Power: Verify 24 V DC nominal; 20.4 to 28.8 V DC permissible; isolate all energy sources before wiring, insertion, or removal
3
Signals: Observe every input/output voltage, current, common, group, polarity, isolation, and protective-device limit
4
Panel: Use documented DIN-rail mounting, clearances, protective earth, cable segregation, ventilation, and IP20 enclosure protection
5
Commissioning: Back up the project, verify addresses and terminals, test one circuit group at a time, and record the results
