Guidelines easily and safely implemented!

The SMX Pessral offers an optimal solution for the strict requirements in the field of elevator technology. With the compact, programmable basic control units SMX10P / 11P , they can be implemented easily and flexibly.

The safety modules are EU-type tested as PESSRAL component up to SIL 3 applications. The integrated secure logic control in combination with a variety of safety functions for speed, ramp and position monitoring leaves every scope for specific solutions and use of proven components. With the easy-to-configure data interface, you can adapt to your elevator control quickly and safely!
