Extended Product Information
FAQs
What is the primary function of the Siemens 3RX9501-0BA00?
Its primary function is to provide a stable 30V DC power supply specifically for AS-Interface (AS-i) networks, along with integrated safety features.
Can I use this power supply for general DC equipment?
No, this unit is specifically designed for AS-Interface networks and is not suitable as a general-purpose DC power supply due to its regulated output voltage and current characteristics.
What is the maximum current this module can supply?
The module can supply a maximum of 3 Amperes (3A) to the AS-i network.
Does this module protect against overloads?
Yes, it features integrated overload detection which will shut down the power supply to prevent damage if the current exceeds safe limits.
What input voltages are supported?
The module supports input voltages of 120V AC or 230V AC at a frequency of 50/60 Hz.
What is AS-i data decoupling?
AS-i data decoupling is a feature that separates the control signals from the power on the AS-i bus, helping to maintain signal integrity and improve network stability.
What does IP20 mean for this device?
IP20 indicates that the device is protected against solid objects larger than 12.5mm (e.g., fingers) but offers no protection against water ingress. It is intended for use in controlled environments.
Troubleshooting
No output voltage on AS-i bus.
Verify input power connection (120V/230V AC) and ensure it is within the specified range. Check that the AS-i bus is correctly connected and that no short circuits are present. Confirm that the overload or ground fault detection has not been triggered.
Module powers down intermittently.
This may indicate an overload condition or a ground fault. Check the total current consumption of connected AS-i devices. Inspect the AS-i wiring for any potential ground leaks or short circuits. Reduce the load if it exceeds the 3A limit.
AS-i devices are not functioning correctly.
Ensure the 30V DC output is stable and within specification. Verify that the AS-i bus is properly terminated and that all connections are secure. Check the compatibility of the AS-i devices with the power supply.
Ground fault detection alarm is active.
Immediately disconnect power and inspect the AS-i network wiring and connected devices for any signs of insulation damage or grounding issues. Repair any faults before restoring power.

Setup, Compatibility & Care
Setup:
Mounting: Securely mount the module onto a standard DIN rail within a control cabinet.
Power Connection: Connect the appropriate input voltage (120V AC or 230V AC at 50/60 Hz) to the designated input terminals. Ensure proper grounding.
AS-Interface Connection: Connect the AS-i output terminals to the AS-i bus. Ensure correct polarity.
Ground Fault Test (Recommended): Perform an initial test of the ground fault detection feature as per local electrical codes and Siemens guidelines.
Compatibility:
This module is specifically designed for AS-Interface (AS-i) networks. It is not a general-purpose DC power supply.
Ensure the total current draw of your AS-i devices does not exceed the 3A output limit.
Verify that your control system and connected AS-i devices are compatible with the 30V DC output.
Care:
Keep the module clean and free from dust and debris. Use a dry or slightly damp cloth for cleaning; avoid solvents.
Ensure adequate ventilation around the module within the control cabinet.
Periodically inspect wiring connections for signs of wear or damage.
