S-DIAS Safety System

S-DIAS Safety System

Fully integrated or stand-alone

Thin, flexible and cost-optimized – that is the S-DIAS Safety system. The modular Safety solution for the DIN rail consists of a Safety controller (SCP), which monitors or controls the application and the corresponding Safe I/O modules.

S-DIAS Safety – Hot Facts

S-DIAS Safety is a part of the modular S-DIAS control and I/O system (IP20), which offers the highest performance and package density, high mechanical stability and simple handling.

The TÜV-certified Safety system can also be used as a stand-alone solution. Existing machines and equipment can therefore be gradually equipped with Safety functions.  


  • Modern: designed for the highest Safety requirements – SIL 3/PL e, Cat.4
  • Compact: module dimensions of only 12.5 x 104 x 72 mm (W x H x D) - Safety PLC and I/Os
  • Flexible: individual adaptation to requirements through modular configuration
  • Efficient: minimal wiring and comfortable engineering with the LASAL SAFETYDesigner
