The rotational speed monitor rotas takes on an important role in complex systems. Working independently, it takes the load off the higher level control system. If problems occur, it triggers an alarm function via its relay outputs.

In shipping applications, the rotas  acts as a secondary safety circuit to shut down the engines in emergencies.

The rotas is approved as an emergency stop system by DNV GL.
