Product Description:

• The Siemens 6ES7307-1BA01-0AA0 is a single-phase, regulated power supply unit for the SIMATIC S7-300 PLC family and associated ET 200M distributed I/O systems. It converts a wide range of AC input voltages (120 V AC or 230 V AC, with automatic range selection) into a stable and regulated 24 V DC output at 2 Amperes (A). This power supply is essential for powering the CPU, communication modules, digital and analog I/O modules, and various 24 V DC field devices connected to the S7-300 system. Its robust design ensures reliable operation in industrial environments.

  Important Note: As of October 1, 2023, this product has entered the phase-out stage (PM400). While still available for spare parts and service, it’s no longer actively produced for new designs.

  Precautions

  When installing and operating the Siemens 6ES7307-1BA01-0AA0, observe the following critical precautions:

  • Qualified Personnel: All installation, wiring, commissioning, and maintenance must be performed exclusively by qualified and authorized personnel familiar with electrical systems, industrial automation, and relevant safety standards.
  • Power Disconnection: Always ensure all incoming AC power to the power supply unit and the entire S7-300 system is completely disconnected and locked out before performing any wiring or maintenance. Verify zero voltage.
  • Correct Wiring:
    • Connect the AC input correctly according to the provided wiring diagram, observing live (L), neutral (N), and protective earth (PE) connections.
    • Ensure proper wire gauges are used for both AC input and DC output to handle the current load safely.
    • Strictly adhere to local and national electrical codes.
  • Grounding: Proper grounding of the power supply and the entire S7-300 system is essential for safety and to minimize electromagnetic interference (EMI).
  • Ventilation: Install the power supply in a control cabinet with adequate ventilation to ensure proper heat dissipation and prevent overheating. Maintain specified clearance distances.
  • Load Management: Do not exceed the rated 2A output current. Ensure the total current draw of all connected 24 V DC devices (CPU, modules, sensors, etc.) remains within the power supply’s capacity.
  • Environmental Conditions: Operate and store the unit strictly within the specified temperature and humidity ranges. Avoid exposure to direct sunlight, excessive vibration, shock, or corrosive atmospheres.
  • Mounting: Securely mount the power supply onto the designated S7-300 mounting rail.
  • Documentation: Always refer to the official Siemens SIMATIC S7-300 system manuals and the specific datasheet for the 6ES7307-1BA01-0AA0 for detailed installation, wiring, and safety instructions.
