Safety control unit (SCU)

Do you own old rolling stock and want to upgrade them, but the control technology was discontinued by the manufacturer or is no longer available?

Do you want to upgrade your vehicles with additional functions and are looking for a certified safety control unit, including software?

Is a suitable fall-back solution or a monitoring system for highly safety-related functions still unavailable?

AAIT has designed a universal safety control unit for recurring tasks in the railway vehicle.
The programmable controller is certified up to SIL 3 in accordance with IEC 61508. Numerous typical railway functions have already been developed and have undergone expert assessment up to SIL 3 in accordance with EN 50128. The controller can be upgraded remotely and provides flexible application options.

Application options

  • Speed detection
  • Speed thresholding (traction enabling, door control, standstill)
  • Safety loops
