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.


Lean

  • 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)

Networked

  • 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

Modular

  • 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

Intelligent

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

News

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.
