Description

SIEMENS 6ES7621-1AD00-6AE3 Power Supply Module

Product Dimensions：

The SIEMENS 6ES7621-1AD00-6AE3 belongs to the SIMATIC C7 family. This specific unit is a “complete system” that integrates a SIMATIC S7-300 PLC CPU with an Operator Panel (OP) into a single, compact device.

1. Product Detailed Description

The 6ES7621-1AD00-6AE3 is a SIMATIC C7-621 control system. It is designed for applications where space is at a premium and seamless integration between the controller and the human-machine interface (HMI) is required. It features a built-in character-based display and a membrane keyboard for machine operation and monitoring.

2. Technical Parameters

Below are the key technical specifications for this module:

3. Product Advantages

• Space-Saving Design: By combining the PLC and HMI into one housing, it significantly reduces the footprint in the control cabinet.

• Reduced Wiring: Internal communication between the CPU and the operator panel is pre-configured, eliminating the need for external cables between the two.

• Seamless Integration: Programmed using standard SIMATIC STEP 7 software, ensuring a consistent engineering environment.

• Cost-Effective: Often more economical than purchasing a separate S7-300 CPU and a dedicated Operator Panel.

• Durability: The front panel is designed for industrial environments, offering resistance to dust and moisture.

4. Safety & Operating Precautions

• Legacy Status: Please note that the SIMATIC C7 series is largely discontinued (obsolete). Finding new units may be difficult, and they are primarily available as refurbished or spare parts.

• Power Supply: Always ensure a stable 24V DC power source. Polarity reversal or voltage spikes can damage the integrated electronics.

• Backup Battery: Check the status of the internal backup battery regularly to prevent the loss of data or the user program during power outages.

• Mounting: Ensure the gasket is properly seated during installation to maintain the IP65 protection rating against liquids.

5. Product Applications

The C7-621 is ideal for small to medium-sized machines requiring localized control, such as:

• Packaging Machinery: Controlling conveyor speeds and managing basic labeling parameters.

• Textile Machines: Monitoring tension and motor controls.

• Water Treatment: Small-scale pump control and status monitoring.

• Food & Beverage: Temperature control and simple batch processing.
