Compact Terminals SCTSi IO-Link

Flexible, Fully Networked Vacuum Generation

Variety, optimization of production processes, and continuous energy and process control are the challenges of the future. In order to meet these demands, powerful, flexible and energy-efficient vacuum systems are required. The answer is our Compact Terminal SCTSi IO-Link, a compact unit of several vacuum generators for simultaneously and independently handling different parts with a single vacuum system.

Handling of airtight and slightly porous workpieces
Central unit for vacuum generation, control and monitoring
Integration into fully automated handling and production systems
Central compressed air and power supply for up to 16 ejectors
Direct connection to the controller via only one data line
Modular design with different, individually controllable vacuum circuits for handling different workpieces
Easy configurability of process and device parameters via IO-Link or NFC
Reduction of compressed air consumption by up to 80 % thanks to automatic air saving function
  • Lean and central compressed air supply (1)
  • NFC chip (2) for reading and writing process information
  • Central energy supply and IO-Link connection M12, 5-pin, using the control module (3)
  • Vacuum connections (5) using threaded connectors
  • Compact vacuum terminal consisting of up to 16 blocked compact ejectors (4)

You can choose between different nozzle Technologies and sizes,
connections or rest positions for the suction Valve (NO/NC/IMP).
A maximum of 4 different ejector blocks are possible.
From 9 ejectors upwards, a larger hose Diameter is required for compressed air supply.

Near-Field Communication (NFC)
Near-Field Communication (NFC)
  • Reliable communication via an energy-neutral point-to-point connection
  • Visible data – Both statistical data (such as the serial number) and dynamic process data (such as switching points) can be read out
  • Parameterization option – An app can be used to parameterize the SCTSi IO-Link directly from a smartphone
Networking in Industry 4.0 Systems
Networking in Industry 4.0 Systems
  • The IO-Link connection means that recorded data can be viewed and used all the way up to the control level, which allows for bidirectional parameterization and diagnostics in all conventional field-bus systems
  • Condition monitoring increases system availability by providing detailed analyses of the system’s condition and early detection of faults
  • Predictive maintenance improves the performance of gripping systems
  • Energy monitoring optimizes the vacuum system's energy consumption
Automatic Air Saving Function
Automatic Air Saving Function
  • Switches off the suction function once a safe vacuum value has been reached until the next cycle or until the vacuum falls below the safe vacuum value
  • Various configuration values and air saving settings can be programmed separately for each ejector
  • Reduction of compressed air consumption by up to 80 %
Integrated Electronic Sub-Bus System
Integrated Electronic Sub-Bus System
  • Electronic control can be implemented with just a single cable
  • Comprehensive data communication via IO-Link and near-field communication (NFC)
