Siemens 6ES7307-1EA01-0AA0 SIMATIC S7-300 PS 307 Power Supply

Description

This is the Siemens 6ES7307-1EA01-0AA0, a stabilized PS 307 power supply module engineered specifically for the SIMATIC S7-300 PLC system. It reliably converts a standard 120/230V AC line voltage into a regulated 24V DC output, providing the essential power backbone for the entire S7-300 rack. With a robust output current capacity of 5 A, this module ensures stable operation for the CPU and multiple I/O modules, even in fully expanded configurations, preventing voltage dips that could lead to system faults.

• ■5 A rated output current capacity
• ■Wide-range AC input for global compatibility
• ■Automatic input voltage range selection (120/230V AC)
• ■Designed for seamless integration into the SIMATIC S7-300 rack
• ■Provides electrical isolation to protect sensitive control electronics

Applications

• ■Manufacturing and Assembly Lines
• ■Process Control Systems
• ■Material Handling and Conveying
• ■Building Automation Systems
• ■Water and Wastewater Treatment Facilities

Installation Guidelines

1. 1 Verify that all power to the S7-300 rack is de-energized and locked out according to safety procedures.
2. 2 Mount the module onto the SIMATIC S7-300 mounting rail, typically on the far left side of the rack assembly. Ensure it is securely seated.
3. 3 Connect the 120/230V AC line, neutral, and protective earth (PE) conductors to the corresponding input terminals on the front of the module. Verify correct polarity and secure connections.
4. 4 Slide the module to the right to engage its backplane connector with the adjacent CPU or interface module, establishing the 24V DC power link to the system bus.
5. 5 After all modules are installed and wiring is double-checked, remove the lockout/tagout and restore power to the system. Verify the "24V DC" indicator LED on the front of the module is illuminated.
