• Dual input voltage capability: 115/230V AC
• Output configuration: 30V DC / 4A for AS-i bus power
• Auxiliary output: 24V DC / 5A for peripheral device support
• Robust industrial design for reliable performance in control cabinets

Applications

This power supply is utilized in industrial automation systems where AS-Interface is employed for field-level communication. It is commonly found in manufacturing lines, material handling systems, and machine building applications where decentralized I/O, sensors, and actuators are connected via the AS-i bus.

Technical Specifications

Installation Guidelines

• Ensure the power supply is mounted in a vertical position to allow for proper convection cooling.
• Maintain adequate clearance around the unit to prevent overheating.
• Verify that the input voltage matches the selected range (115V or 230V) before applying power.
• Use appropriate wire gauges for the load requirements and ensure all terminal connections are tightened to the specified torque.
• Always disconnect the main power supply before performing any wiring, maintenance, or module replacement.
• Ensure the unit is properly grounded to the cabinet chassis to minimize electromagnetic interference (EMI).

FAQ

Is this power supply suitable for standard 24V control circuits?

The 3RX9306-1AA00 provides both a 30V output specifically for the AS-Interface bus and a 24V auxiliary output. The 24V output can be used for secondary control devices, but the 30V output must be reserved for the AS-i network components.

What is the primary function of this module?

Its primary function is to provide the regulated 30V DC power required for AS-Interface communication and to power connected field devices, ensuring the network operates within the required voltage tolerances.
