2. Pneumatic Flow Regulation in Packaging Machinery

The module is ideal for packaging machinery that uses pneumatic actuators for gripping, sealing, or diverting products. It precisely regulates air pressure or flow rates by controlling proportional pneumatic valves, ensuring delicate product handling and optimizing high-speed operations.

Problem Solved

With its two independent channels (1.6A each) and ability to drive proportional pneumatic valves, the 750-632 enables precise and repeatable pneumatic movements. This improves throughput, reduces material damage, and ensures consistent quality in automated packaging processes, with an IP20 rating suitable for typical control cabinet environments.

3. Process Fluid Dosing in Chemical or Pharmaceutical Industries

For process industries requiring accurate dosing of fluids (liquids or gases), the WAGO 750-632 can drive proportional control valves. This application is suitable for maintaining product consistency, quality, and safety in general industrial areas (non-hazardous/explosive zones).

Problem Solved

The module provides current-controlled PWM outputs to precisely operate proportional valves, enabling accurate and repeatable fluid dosing. Features like characteristic curve adaptations and ramp adjustments ensure controlled flow rates, crucial for product consistency, while its 0-55°C operating temperature and IP20 rating fit standard industrial control cabinet installations.
