The Siemens 3RX9306-1AA00 is a high‑performance AS‑Interface combi power supply unit designed for industrial automation networks. As a central component of the Siemens SIRIUS AS‑i product family, the 3RX9306-1AA00 provides a stabilized 30 V DC supply for the AS‑i bus while delivering a separate 24 V DC output with integrated data decoupling. Its built‑in short‑circuit protection and high‑efficiency design simplify wiring and enhance system reliability. Ideal for powering up to 62 standard AS‑Interface slaves, this 3RX9306-1AA00 ensures stable, interference‑free operation across the entire actuator‑sensor network.
Industrial automation and control systems (factory automation, logistics systems)
AS‑Interface actuator‑sensor networks
Smart production lines and legacy system retrofitting
Robotic systems, manufacturing lines, and process control environments
Outdoor or extreme‑temperature installations (wide operating range)
Combi Output (AS‑i + Aux 24 V): Provides both a regulated 30 V DC AS‑i bus supply and a separate 24 V DC output with integrated data decoupling, eliminating the need for external components.
Built‑in Short‑Circuit Protection: Electronic current limiting and auto‑recovery short‑circuit protection safeguard the network and connected devices.
Wide Input Voltage Range: Switchable 115 V AC / 230 V AC input with broad tolerances (102‑132 V and 195‑253 V) ensures global compatibility.
High Efficiency & Low Ripple: ≥ 85 % efficiency and very low output ripple/spikes guarantee clean, stable power for reliable AS‑i communication.
Robust Industrial Design: IP20 protection, spring‑loaded terminals for tool‑free wiring, and standard DIN rail mounting simplify installation and maintenance.
Extreme Temperature Resilience: Operates reliably in ambient temperatures from -45 °C to +55 °C, suitable for harsh and outdoor applications.
AS‑i Bus Power Supply: Converts single‑phase AC mains (115/230 V) into a regulated, floating 30 V DC output that powers the AS‑Interface bus, including both actuator and sensor devices.
Auxiliary 24 V DC Supply: Provides an additional isolated 24 V output (4/5 A) with integrated data decoupling for powering peripheral devices such as sensors, encoders, or small actuators.
Data Decoupling: The internal decoupling ensures that AS‑i communication signals (modulated on the power line) remain undisturbed, enabling simultaneous power transmission and data exchange over the same two‑wire cable.
Short‑Circuit & Overload Protection: Continuously monitors output current and automatically limits it in case of overload or short circuit, then recovers once the fault is cleared.
Mains Buffering: Maintains output for at least 20 ms during power dips, preventing brief outages from disrupting the AS‑i network.
Q1: What is the primary purpose of the Siemens 3RX9306-1AA00?
A1: The 3RX9306-1AA00 is an AS‑Interface combi power supply that provides both a regulated 30 V DC supply for the AS‑i bus and a separate 24 V DC output with integrated data decoupling, eliminating external components.
Q2: How many AS‑Interface slaves can the 3RX9306-1AA00 power?
A2: With its 4 A output, the 3RX9306-1AA00 can power up to 62 standard AS‑Interface slaves (including A/B addressing mode), making it suitable for most medium‑sized AS‑i networks.
Q3: Does the 3RX9306-1AA00 have built‑in short‑circuit protection?
A3: Yes, the 3RX9306-1AA00 features electronic short‑circuit protection with auto‑recovery, which limits the output current during a fault and automatically restores normal operation once the fault is cleared.
Q4: What is the efficiency rating of the 3RX9306-1AA00?
A4: The 3RX9306-1AA00 achieves an efficiency of at least 85 % at rated output, reducing heat dissipation and energy costs in the control cabinet.
Q5: Can the 3RX9306-1AA00 be used in outdoor or high‑temperature environments?
A5: Yes, the 3RX9306-1AA00 is designed for extreme conditions, with an operating temperature range of -45 °C to +55 °C, making it suitable for outdoor installations and harsh industrial settings.
