Product Overview
The Siemens 6AG1433-2BA20-7AA0 is a SIPLUS PS PSU300S power supply used to provide electrical power for compatible automation equipment. It belongs to the SIPLUS range and is suited to industrial installations where the power supply forms part of a distributed control or automation cabinet.
In an automation system, the power supply establishes the required supply path for connected control equipment and associated system components. Stable power availability is essential for maintaining controller operation, I/O communication, and the correct response of connected automation devices.
The PSU300S is particularly relevant to control cabinets where power distribution needs to be organized around the automation hardware. It can be used alongside PLC components, I/O assemblies, communication equipment, and other cabinet-mounted devices according to the applicable system configuration.
The SIPLUS designation makes this type of power supply relevant to industrial environments with more demanding environmental requirements. Selection should always take into account the specific system configuration and applicable Siemens installation requirements.

Working Principle
The 6AG1433-2BA20-7AA0 operates as the power conversion and distribution point between the available electrical supply and connected automation equipment. Input power is processed by the power-supply circuitry and delivered to the connected system within the operating requirements of the installation.
Electrical Supply → 6AG1433-2BA20-7AA0 → Automation Power Distribution → PLC / I/O / Communication Equipment
During normal operation, the power supply supports the electrical requirements of the connected automation hardware. The downstream devices then use this supply for their own processing, signal acquisition, communication, or control functions.
A power-supply fault can affect multiple devices simultaneously. For this reason, troubleshooting should distinguish between an issue originating at the PSU, an interruption in downstream wiring, and a fault within the connected automation equipment.
Role in a Siemens SIPLUS Automation Power Architecture
The 6AG1433-2BA20-7AA0 forms part of the power layer supporting compatible Siemens automation equipment. It does not execute PLC logic or process field signals; instead, it maintains the electrical supply required by the control-system components connected downstream.
Incoming Power → PSU300S Power Supply → Automation Power Distribution → PLC / I/O / Communication Devices
| System Element | Function |
|---|---|
| Incoming Electrical Supply | Provides the source power |
| 6AG1433-2BA20-7AA0 | Supplies power to compatible automation equipment |
| Power Distribution | Routes supply power to connected devices |
| PLC / CPU | Executes automation and control logic |
| I/O Modules | Exchanges signals with field equipment |
| Communication Modules | Transfers system and process data |
| Field Equipment | Performs sensing and control functions |
The power supply therefore serves as a foundation for the electrical operation of the associated automation hardware.
Industrial Applications
| Application | Typical Use |
|---|---|
| Industrial Control Panels | Powering automation and control-system equipment |
| PLC Systems | Supplying compatible controller components |
| Process Automation | Supporting distributed control equipment |
| Manufacturing Machinery | Power source for cabinet-mounted automation |
| Production Lines | Supporting PLC, I/O, and communication hardware |
| Utility Systems | Automation power distribution |
| Machine Control Cabinets | Supplying control-system components |
| Industrial Retrofit | Replacement of compatible automation PSUs |
Installation and Maintenance
- Confirm that the 6AG1433-2BA20-7AA0 is suitable for the intended automation configuration before installation.
- Isolate the electrical supply according to the approved maintenance procedure before working on the power circuit.
- Verify the mounting position and available cabinet space before installing the unit.
- Check the incoming and outgoing wiring against the approved electrical drawings.
- Confirm terminal identification before connecting the power supply.
- Ensure that downstream equipment is compatible with the supply provided by the installed PSU.
- Keep power wiring properly routed and secured within the control cabinet.
- Inspect terminals for looseness, overheating, corrosion, or signs of mechanical damage.
- Energize the power supply under controlled commissioning conditions.
- Verify that connected automation equipment starts and operates normally after power is applied.
- Investigate repeated power interruptions by checking the PSU, incoming supply, wiring, and downstream load separately.
- After replacement, perform a complete power-distribution and automation-system functional test before returning the equipment to normal operation.

Technical FAQs
What is the function of the PSU300S in an automation cabinet?
The PSU300S serves as a power-supply component for compatible automation equipment. It converts and supplies electrical power required by downstream control-system components according to the applicable installation configuration.
What symptoms can indicate a power-supply problem?
A complete loss of several connected devices, unexpected controller shutdowns, repeated resets, or unstable system operation can indicate a problem in the power path. Incoming power, PSU operation, terminals, and downstream wiring should be checked systematically.
Can a power-supply fault affect multiple PLC modules?
Yes. When several PLC, I/O, or communication components depend on the same power path, an interruption or abnormal condition at the power supply can affect multiple devices at the same time.
What should be checked after replacing the 6AG1433-2BA20-7AA0?
Verify the wiring, terminal assignments, power input, downstream connections, and system startup behavior. The connected PLC, I/O, and communication equipment should be checked to confirm that all affected components return to normal operation.
