SIEMENS 6ES7305-1BA80-0AA0 PLC Power Supply Module

Product Dimensions：

The Siemens 6ES7305-1BA80-0AA0 is an industrial DC/DC power supply module from the SIMATIC S7-300 product family (often designated as PS 305 2A outdoor / wide-range model). It converts a wide DC input voltage range into a stabilized 24V DC output power supply to feed S7-300 CPUs, I/O modules, and peripheral sensors/actuators.

Product Detailed Description

Designed for environments where standard AC utility power is unavailable or where battery/DC bus power is utilized (such as solar systems, mobile equipment, or substations), the 6ES7305-1BA80-0AA0 accepts an ultra-wide input voltage range of 24V DC to 110V DC. It mounts directly onto standard SIMATIC S7-300 DIN rails and connects seamlessly to the CPU or adjacent I/O modules using standard bus connectors and front-panel wiring.

Technical Parameters

Product Advantages

• Ultra-Wide Input Voltage Range: Handles inputs from 16.8V to 138V DC without requiring jumper switches or manual tap selection, making it extremely versatile for fluctuating DC grids.
• S7-300 Form Factor: Features the exact physical profile and mounting system of standard S7-300 modules, maintaining panel aesthetic and compact layout integrity.
• Robust Industrial Design: Provides short-circuit and open-circuit protection with automatic restart, ensuring high system uptime without replacing fuses after minor external faults.
• Galvanic Isolation: Offers safe electrical isolation between the primary DC power source and the sensitive 24V DC secondary control circuits.

Important Considerations (Precautions)

• Current Limitation (2A Output): Rated for 2 Amps maximum. Calculate total system current draw (CPU + I/O backplane + field sensors) to ensure it stays below 2A. If your load exceeds 2A, an external supplementary power supply or a higher-rated unit is required.
• Heat Dissipation: Ensure proper vertical clearance (at least 40 mm top and bottom) on the DIN rail to allow natural convection cooling.
• Polarity Check: Double-check input wiring polarity before applying power to avoid blowing internal protective components.
• Input Voltage Dips: During heavy battery discharge or cold-engine cranking in vehicle applications, ensure input voltage does not drop below 16.8V DC to avoid module shutdown.

Product Applications

• Substations & Energy Utilities: Powered directly from 110V DC station battery banks to run automation controllers.
• Railway & Transportation: Used in rolling stock, wayside control cabinets, and signaling equipment powered by 24V, 48V, 72V, or 110V DC onboard supplies.
• Solar & Off-Grid Automation: Ideal for remote telemetry units (RTUs) or water monitoring stations operating on 24V/48V battery systems.
• Mobile Heavy Machinery: Installed on mining trucks, cranes, and marine vessels where generator/battery power fluctuates heavily.
