Safety controllers enable flexible
configuration
Configurable safety controllers allow multiple safety functions to be implemented simultaneously with a single module.
Approved for SIL3 applications in line with IEC61508, and Category 4 applications in line with EN954-1, the new Preventa XPS MC configurable safety controllers from Telemecanique, a brand of Schneider Electric, cut cabling time, simplify system design and save money by allowing multiple safety functions to be implemented simultaneously with a single module Preventa XPS MC safety controllers are available with either 16 or 32 safety inputs, and provide eight independent safety outputs

Altivar drives go to the movies!
Bristol cinemagoers are now enjoying improved screenings of classic and archive movies, thanks to an Altivar 18 variable speed drive from Telemecanique.
To ensure maximum versatility and to minimise wiring, the controller is configured via software.
They also support communication with PLCs via Modbus, CANopen or Profibus DP fieldbus, as well as offering facilities for direct connection to other types of automation systems.
A library of 30 certified safety functions, covering applications as diverse as emergency stop monitoring and shaft breakage detection, is incorporated in every Preventa XPS MC controller.
User simply select the functions needed for their specific application with the aid of the Preventa XPS MCWIN software package, which uses convenient drag-and-drop techniques and runs on any modern PC.
This configurability is a particular benefit in applications where full details are not known at the design stage, as the controller can be set up after is received, or even after installation in the control panel.
The Preventa XPS MCWIN software also allows safety configurations to be saved to a CD after validation, for archiving or for easy transfer to other Preventa XPS MC controllers.
LEDs on the front face of Preventa XPS-MC controllers provide instant visual confirmation of status and first-level diagnostic facilities.
Further extensive diagnostic functions are provided, and can be readily accessed via a Magelis HMI terminal, or a fieldbus connection.
For applications requiring fewer safety functions, Preventa XPS MP controllers are available which provide two simultaneous safety functions, selected from a library of 15.
Also available are Preventa XPS single-function safety relays which can be supplied in types to cover all common safety requirements.
