Compact Terminal SCTSi Ethernet

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 Ethernet, a compact unit of several vacuum generators for simultaneously and independently handling different parts with a single vacuum system.

The compact terminal SCTSi is sort of the masterpiece of our engineers, a compact and powerful unit for vacuum generation in automated systems. Now Schmalz has enhanced the Ethernet version of the terminal by adding new modules. Via an IO-Link master that can be integrated into the terminal, field devices can be connected via IO-Link and thus communicate directly with the PLC. Digital field devices such as sensors are integrated via digital input modules – without separate I/O modules. The terminal thus becomes the central control unit for vacuum gripping systems.


  • Central compressed air and power supply for up to 16 ejectors
  • Direct connection to the controller via only one data line
  • Space saving (no additional IO-Link master or I/O modules)


  • Can be integrated in a wide range of field-bus systems
  • Only one station in the network, even if devices are connected to the SCTSi


  • Simple construction of different, individually controllable vacuum circuits
  • Single and multi-stage vacuum generation
  • Ejectors are individually selectable according to nozzle size, NO / NC / impulse or nozzle type


  • All vacuum circuits can be separately controlled
  • Process transparency, energy consumption control and a variety of diagnostic functions for use in intelligent factories


IO-Link master

  • Connection of intelligent field devices (sensors and actuators)
  • Direct connection to the controller via only one data line

Digital input modules

  • Connection of digital field devices (sensors)
  • Up to 4 expansion modules with 4 ports each (M12-5 socket)

Impulse valves (IMP)

  • Ejector discs with bistable suction valve increase process reliability
  • If the actuator voltage fails, the ejector remains in the last active state
  • Valve requires only a short voltage pulse for switching

ETL certified

The SCTSi Ethernet is Schmalz's first product to receive an ETL certification (short for Electrical Testing Laboratories) from Intertek. This certification confirms compliance with industry standards that guarantee certain minimum safety requirements.

The ETL certification of the SCTSi Ethernet includes both the USA and Canada. ETL certification is equivalent to UL or CSA certification.

Configuration Code – Selection and Ordering Aid

The Compact Terminal SCTSi Ethernet was developed to connect multiple ejectors. Use the following code to configure a Compact Terminal SCTSi Ethernet to match your application.

Highlights of the Compact Terminal SCTSi Ethernet

Ideal for use in the Smart Production of the Future

The Compact Terminal SCTSi Ethernet offers an enormous range of innovative, energy-saving technologies and networking options for use in intelligent factories.

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 Ethernet directly from a smartphone

Networking in Industry 4.0 Systems

  • The Ethernet 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

  • 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

  • Electronic control can be implemented with just a single cable
  • Comprehensive data communication via Ethernet and near-field communication (NFC)
  • All ejectors can be separately programmed and controlled

Eco-Nozzle Technology

  • Eco-nozzle technology provides a considerably higher suction rate with minimized compressed air consumption for energy-efficient vacuum generation
