NEW 6ES7901-3DB30-0XA0

Key Features & Specifications:

• Length: Measures 530 mm (approximately 20.9 inches), providing extended space compared to shorter rails in the series. This longer profile accommodates larger configurations of S7-300 modules, such as multiple CPUs, power supplies, signal modules, or special function modules.
• Mechanical Design: Constructed from robust metal with a standardized profile, it is compatible with 35 mm DIN rails—an industry standard for mounting components in control cabinets. Its rigid structure ensures modules remain firmly secured, even in environments with vibration or mechanical stress, common in industrial settings.
• Electrical Integration: Integrates a built-in backplane bus that establishes automatic electrical connections between mounted S7-300 modules. This eliminates the need for external wiring between modules (e.g., CPU to I/O modules or power supply), simplifying system assembly, reducing installation time, and minimizing connection errors.
• Compatibility: Specifically engineered for SIMATIC S7-300 modules, including:
  • S7-300 CPUs (e.g., 314, 315, 317).
  • Power supply modules (e.g., PS 307).
  • Signal modules (e.g., SM 321 digital inputs, SM 322 digital outputs, SM 331 analog inputs).
  • Communication processors and special function modules.

Installation & Scalability:

• Mounting: Installed onto standard 35 mm DIN rails within control cabinets. S7-300 modules are clipped directly onto the rail, where they mechanically lock in place and electrically engage with the backplane bus—ensuring a secure and reliable connection.
• System Flexibility: The 530 mm length is ideal for medium to large S7-300 configurations requiring more modules than shorter rails (e.g., 350 mm) can accommodate. For even larger systems, it can be complemented with longer rails (e.g., 830 mm) as needed.

Industrial Durability:

Applications:

• Control cabinets for complex machinery (e.g., production lines, robotics, or material handling systems) requiring multiple I/O modules.
• Process control setups with extensive analog/digital signal monitoring and control needs.
• Industrial panels where organized, space-efficient mounting of a larger number of S7-300 components is critical.
