Dedicated Voltage Supply for S5 Peripherals
The Siemens 6ES5956-0AA11 15V module provides a dedicated voltage supply for S5-135U and S5-155U peripheral devices. This module delivers a regulated 15 V DC output to power sensors, encoders, and other field devices. Industrial control systems require stable auxiliary voltages, and this unit provides that capability reliably.
Input and Output Electrical Specifications
This 15V module accepts the backplane voltage and converts it to a stable 15 V DC output. The unit delivers a maximum output current of 2 A, sufficient for multiple peripheral devices. Total output power reaches 30 watts, supporting small to medium sensor networks. Furthermore, the module includes short-circuit and overcurrent protection for safe operation.

Protection Features and Reliability
The Siemens 6ES5956-0AA11 incorporates comprehensive protection mechanisms for safe operation. Short-circuit protection limits the output current to a safe level. Overcurrent protection automatically resets after fault removal. Additionally, the module includes thermal shutdown at 80°C to prevent damage. A front-panel LED indicates the output voltage status.
Physical Design and Installation
This 15V module features a 50 mm housing that fits standard S5-135U and S5-155U rack slots. The unit weighs approximately 0.35 kilograms, allowing straightforward installation. A 20-pin front connector provides access to the output terminals. The module uses screw-type terminals that accept wires from 0.5 mm² to 2.5 mm².
System Integration and Application Areas
You can install this voltage supply module in any standard S5-135U or S5-155U rack slot. The module provides a clean 15 V supply for encoders, position sensors, and analogue signal conditioners. For applications requiring higher current, you can parallel multiple modules with isolation diodes. The unit operates reliably from 0°C to 55°C with proper cabinet ventilation.
Compatibility and Ordering Information
This voltage supply module works with all S5-135U and S5-155U systems that require auxiliary 15 V power. Always verify the total current draw of your peripheral devices before installation. The package includes the module only; field wiring terminals are separate. Ensure proper wiring polarity to avoid damage to connected devices.
