Siemens 3RX9307-1AA00 – AS-Interface Power Supply Unit | SIRIUS 3RG9 Platform
The Siemens 3RX9307-1AA00 is a dedicated AS-Interface (AS-i) power supply unit engineered for the SIRIUS 3RG9 sensor and actuator platform. Designed to power AS-i networks in demanding industrial environments, this unit delivers stable, conditioned 24 VDC output with integrated AS-i bus decoupling — ensuring reliable slave communication across the full network segment. Procurement engineers sourcing AS-i infrastructure components for Siemens-based control architectures will find this unit a direct, specification-matched solution.
Konmask.com supplies the 3RX9307-1AA00 as a verified OEM component, fully traceable and ready for integration into new installations or field replacement of existing SIRIUS AS-i networks.

System Architecture & Signal Flow
The 3RX9307-1AA00 sits between the 24 VDC plant supply and the AS-Interface bus segment. It converts and conditions the 24 VDC input to the AS-i bus voltage (nominally 30 VDC), while simultaneously decoupling the AS-i data signal from the power supply rail. This decoupling is critical: it prevents the power supply’s switching noise from corrupting the AS-i communication signal, and isolates the bus from external 24 VDC transients.
In a typical SIRIUS 3RG9 topology, the 3RX9307-1AA00 feeds one AS-i segment (up to 31 standard or 62 A/B slaves), with the AS-i master (e.g., CP 343-2 or CM AS-i Master ST) connected upstream. Multiple units can be deployed for multi-segment networks, each independently powered and decoupled.

Technical FAQ
- Q: Can the 3RX9307-1AA00 power a full 31-slave AS-i segment?
- A: Yes. The unit is rated for standard AS-i segment loads. For high-current slave configurations, verify total segment current against the unit’s output rating.
- Q: Is an external decoupling choke required?
- A: No. The 3RX9307-1AA00 integrates the decoupling function internally, simplifying installation.
- Q: Is this unit compatible with AS-i Safety (AS-i Safety at Work)?
- A: Yes. AS-i Safety slaves operate on the same bus segment and are powered by the same supply — the 3RX9307-1AA00 is fully compatible.
- Q: What is the input voltage range?
- A: The unit is designed for 24 VDC input (PELV). Consult the Siemens datasheet for tolerance range.
- Q: Can I use this unit outside a control cabinet?
- A: The unit is rated IP20 and is intended for installation inside an enclosure. For outdoor or wash-down environments, an appropriate IP-rated enclosure is required.
