Siemens S7-1200 and S7-1500 PLCs

Siemens S7-1200 and S7-1500 PLCs are the "brain" of the system. In an extraction and air filtration system, the PLC autonomously manages the entire process to ensure that the air remains clean while keeping energy consumption under control. In an air treatment and purification system, efficiency does not depend only on the power of the extraction units, but also on the system's ability to "think" and respond to changing environmental conditions. For this reason, our electrical control panels use Siemens SIMATIC PLCs, the global benchmark for excellence in industrial automation.

In addition to operational management, both Siemens PLCs (S7-1200 and S7-1500) are available in F versions (Fail-safe). In an extraction and filtration system, this means that the same PLC controlling the motors also manages all critical safety functions.

With Siemens Safety PLCs, everything is integrated into a single intelligent system:

• Emergency management: if an operator presses the emergency stop button, the PLC itself ensures the immediate and safe shutdown of the fan or discharge screw conveyor, in compliance with the highest international safety standards (SIL 3/PLe).
• Access monitoring: if a filter inspection door is opened during operation, the Safety PLC detects it instantly and stops moving components before they can cause injury.
• Total reliability: unlike a standard PLC, the Fail-safe version continuously performs internal circuit tests. If an internal fault is detected, the system automatically switches to a "safe state", preventing unexpected start-ups or dangerous malfunctions.
• Complete automation: the system detects when more or less extraction capacity is required and automatically adjusts operation without constant human intervention. It allows the plant cycle to be managed automatically or manually, including all operating functions.

• Production synchronization: the PLC communicates with machine tools or workstations. The extraction system starts automatically when production begins and switches off (or reduces speed) during downtime, providing immediate energy savings.
• Safety and diagnostics: it monitors the condition of motors and sensors. In the event of a fault (such as overheating or pressure loss), the PLC immediately places the system in a safe condition and displays the exact cause of the problem, reducing troubleshooting time to a minimum.
• Industry 4.0: both models are ready for digital integration. Companies can monitor the system from their office and access incentives related to technological innovation and digital transformation.
• Siemens reliability: choosing Siemens means ensuring long-term availability of spare parts and technical support for decades, protecting the customer's investment.

The Siemens S7-1200 is the ideal solution for medium-sized extraction systems.
Compact design: requires minimal space inside the control panel while providing high performance.
Connectivity: features an integrated communication port for easy connection to the company network or touchscreen operator panels.

The Siemens S7-1500 is the most powerful controller, selected for complex systems or applications where precision is critical.
Integrated display: allows system status to be viewed directly on the PLC without the need for external PCs.
Superior performance: manages large amounts of data and sensors, making it ideal for applications requiring detailed reports on emissions and energy consumption.
Advanced safety: integrates Fail-safe functions that ensure the highest protection standards for operators and the environment.
