Core Specifications of the Digital Output Module
The 6ES5415-7AA11 belongs to the Siemens SIMATIC S5 family of digital output modules. This card drives relays, valves, and indicator lamps in industrial control cabinets. Moreover, it suits legacy S5-115U and S5-135U racks that remain in active service.
Each module occupies a single slot in the central rack. Additionally, the unit weighs roughly 0.45 kg with its front connector installed. The front panel measures 20 mm in width and 130 mm in height, while the 7AA11 suffix defines the channel count and output rating.

Interface and Mounting Details
The 6ES5415-7AA11 slides into the S5 rack and connects to the backplane bus. Consequently, technicians complete replacement without rewiring field terminations. This module drives loads through a front screw terminal strip. Therefore, it simplifies wiring for high-density output points.
Optocoupler isolation separates field circuits from the internal logic. Meanwhile, the compact housing fits standard S5 rack clearances.
Performance and Application Notes
Plant operators keep the 6ES5415-7AA11 in service for continuous process control. Furthermore, the module switches 16 independent loads at 24 V DC. Each channel delivers up to 0.5 A for solenoids and pilot lamps. Meanwhile, the optocoupler barrier protects the backplane from field transients.
The module stores no energy internally, since it draws power from the backplane. As a result, it adds minimal load to the S5 power budget.
