The External Vacuum Controller VZP is a compact, lightweight device designed specifically for manifold-mounted vacuum control systems. It features bundled wiring that simplifies installation and ensures reliable connectivity to manifold stations, reducing the need for additional cabling. This dedicated controller enables precise management of vacuum operations in industrial environments where consistent pressure regulation is essential.
The VZP is constructed with durable materials suitable for demanding conditions. Its body uses PVF (Polyvinyl formal) as the primary element material, providing excellent resistance to chemical exposure and environmental degradation. The device is built for long-term reliability in air and vacuum applications compliant with JIS B 8392-1: Class 1.2.1 to 2.4.3 standards.
The controller supports flexible connection options through a push-in fitting or female thread interface, allowing users to select the mounting type that best matches their piping requirements. It is specifically designed for use with manifold systems and includes bundled wiring dedicated to manifold mount applications, streamlining setup and reducing installation time.
The VZP operates within a vacuum range of -100 to 0 kPa and an air pressure range of 0.3 to 0.7 MPa. It is rated for operating temperatures from 5 to 50 ℃ (no freezing) or 0 to 60 ℃ (no freezing), with humidity tolerance between 35% and 85% RH (no dew condensation). The device uses a diffused semiconductor pressure switch/sensor for accurate pressure detection, with a setting range of -99 to 0 kPa. Power consumption is as low as 0.55W, and the maximum current draw is 40 mA.
The VZP offers two output configurations: one with a single switch output (NPN open collector, 30 V 80 mA max., residual voltage ≤ 0.8 V) and another with dual outputs. The controller supports a wide range of vacuum sensor variations, enabling adaptation to diverse industrial applications. The number of manifold stations can be adjusted as needed, allowing for rapid response to changing operational specifications.
The VZP integrates directly into existing vacuum systems via its multi-pin connector, which powers both the supply valve and blow-off valve using a single connection. This centralized wiring design reduces complexity and saves time during installation. The device is rated for proof pressure of 1.05 MPa in the air supply circuit and 0.2 MPa in the vacuum circuit, ensuring robust performance under operational stress.
