UO-EM-EGS4 / UO-EM-EGS41 SIL 2 (speed switch module)

Universal encoder systems

  • Monitor overspeeds and underspeeds
  • Relay contacts / switching outputs: 2 programmable, 1 diagnostics
  • Switching capacity up to 250 V AC/DC and 0.5 A
  • Options: SIL 2 / PL d certification (UO-EM-EGS41)
Overspeed switches

The speed limiters

The speed switch modules are electronic overspeed switches that monitor the defined speeds for overspeed and underspeed. By design they include a switching delay, an inverse direction of rotation evaluation, a direction of rotation dependent switching function and the option to perform a switch test. They are easily programmed via the decoder interface.
