Monitoring and protection overspeed system with SIL2

  • high safety and protection system from Braun
  • SIL2 - compliant
  • provides protection agains ovespeed and reverse direction

  • TMR (Triple Modular Redundancy) incorporating 2oo3 evaluation
  • additional 6 criteria for trip (emergency stop, boielr protection...)
  • 2oo3 architecture - one signal of 3 can be faulty, only two signals will send a trip signal
  • system E16 consists of three monitors E1667, which evaluate speed and addiational trip signals
  • < 15 ms total response time to trip
  • 1 PROFIBUS interface
  • remote test of solenoid trip block by test signals from DCS possible
